grow styles
Which grow style suits you best is completely up to your own wishes and needs. On the grow style list we have mentioned the benefits of each grow style. Perhaps this makes choosing easier for you? Do you still need help? Then use the handy Plagron Product Selector. Based on the selection of three choices you can decide which substrate suits your needs the best.
Our advice is to stick to products from one grow style. The combination of these products ensures an optimum yield. You can combine all UNIVERSAL products with products from all other grow styles. UNIVERSAL products are universally applicable.
You can combine all additives from the UNIVERSAL category with every grow style. However, not all combinations are useful. If you combine the recommended additives and grow styles, we guarantee you an optimal yield.
If you want to grow outdoors in pots, we recommend our 100% NATURAL grow style. These products are ideal when you prefer a quick end-result with the best smell and taste. If you want to grow outdoors in open soil, we recommend you use Mega Worm or Supermix together with Bat Guano to upgrade the soil.
Water requirement depends on the plant itself, the type, the size, age and general health of the plant. These factors all have an influence on the water requirements of the plant. If you want to know when to give your plants water, you should stick a finger into the potting soil. By doing so you can feel how moist the soil is. The top layer will dry out the fastest because of the contact with the air. If you look several centimeters below the surface you will have a better indication of the moisture in the soil. You can learn more about this in our grow topic on the subject.
Unopened products have a shelf life of 4 years. To determine when your product was manufactured, you can e-mail the batchnumber of your product to our servicedesk. An opened product has a guaranteed shelf life of 6 months.
100% NATURAL
Because of its fertilisation through Bat Guano, Batmix gives your plants a strong taste and smell. You should choose Batmix when quality is the most important to you. Royalmix contains a selection of natural solid fertilisers that release the nutrients when the plant needs them. Because of this you can expect a higher development and thus a higher yield. Choose for Royalmix when you want to grow organically and when you want to go for the highest yield with a natural fruity taste. Plagron Allmix has a finer texture than Batmix and Royalmix. Because of this it can better hold more water. This makes Plagron Allmix the right choice if you want to grow organically, in high temperatures, small pots or with high light intensity. Furthermore Plagron Allmix is very well suited for upgrading normal garden soil. Are you an experienced 100% NATURAL grower and do you want as much control over the nutrient? Choose Promix with which you have to feed your plants yourself from day one.
When you choose products from our 100% NATURAL Grow Style you are growing organically and you don't have to measure the pH and EC values of nutrient solutions. An EC meter can't measure all organic nutrients. The biological life in the substrates from the 100% NATURAL grow style will ensure that the nutrients remain available for your plants and will help to stabilise the pH value. That’s why you don’t have to measure pH values.
Products from the 100% NATURAL grow style are Control Union certified and can be used for organic growing. Thanks to abundant soil life in the substrates it's an easy grow style that can balance out it's own pH and EC values.
batmix
Batmix is fertilised for about six weeks. When you need to start giving nutrients depends on conditions such as the amount of light per square meter, the type of plant and other factors. It takes about two weeks for organic nutrients to become available to the plant. If you start fertilising from the fourth week, the nutrients will be available in week six, right at the point were the pre-fertilisation of the Batmix runs out. Check the grow schedule to find out if you need Alga Grow or Alga Bloom and in what dosage.
No, combined with our 100% NATURAL Grow Style you don't have to regulate the pH and EC value.
Batmix is maximally fertilised. For young plants that are not yet accustomed to high EC-values, it may be difficult when they are suddenly planted into a maximum fertilised soil. Therefore we recommend to flush the Batmix before putting the plant into the Batmix. This is done by filling the pot (eg 10 liters) with Batmix and  rinsing it with 5 to 10 liters of water. After this, the plant can be planted directly. The fertilisers that are absorbed directly will be flushed out with the water. Within the following days, the EC value in Batmix will rise again and gradually the non absorbable fertilisers will be released.
Yes, we advise you to mix Batmix with full ground when your soil outside is very clayey. If your soil is very airy we would recommend you use Bat Guano.
royalmix
When you need to start giving nutrients depends on conditions such as the amount of light per square meter, the type of plant and other factors. It takes about two weeks for organic nutrients to become available to the plant. If you start fertilising from the fourth week, the nutrients will be available in week six, right at the point were the pre-fertilisation of the Royalmix runs out. Check the grow schedule to find out if you need Alga Grow or Alga Bloom and in what dosage.
No, combined with our 100% NATURAL Grow Style you don't have to regulate the pH and EC values of nutrient solutions.
Our Royalmix is maximally fertilised. For young plants that are not yet accustomed to high EC-values, it may be difficult when they are suddenly planted into a maximum fertilised soil. Therefore we recommend to flush the Batmix before putting the plant into the Royalmix. This is done by filling the pot (eg 10 liters) with Royalmix and  rinsing it with 5 to 10 liters of water. After this, the plant can be planted directly. The fertilisers that are absorbed directly will be flushed out with the water. Within the following days, the EC value in Royalmix will rise again and gradually the non absorbable fertilisers will be released.
plagron allmix
When you need to start giving nutrients depends on conditions such as the amount of light per square meter, the type of plant and other factors. It takes about two weeks for organic nutrients to become available to the plant. If you start fertilising from the fourth week, the nutrients will be available in week six, right at the point were the pre-fertilisation of the Plagron Allmix runs out. Check the grow schedule to find out if you need Alga Grow or Alga Bloom and in what dosage.
No, combined with our 100% NATURAL Grow Style you don't have to regulate the pH and EC value of nutrient solutions.
Plagron Allmix is fully fertilised. Young plants that are not yet accustomed to high EC-values may struggle when they are suddenly planted into a maximally fertilised soil. Therefore we recommend that you flush the Plagron Allmix before putting the plant into the Plagron Allmix. This is done by filling the pot (eg 10 liters) with Plagron Allmix and  rinsing it with 5 to 10 liters of water. After this, the plant can be planted directly. The directly available nutrients will be flushed out with the water. Within the following days, the EC value in Plagron Allmix will rise again and gradually the non absorbable fertilisers will be released.
promix
You should start adding nutrition from the first day. Start off with Alga Grow and switch to Alga Bloom later. More information about dosage and type of basic nutrient can be found in our Grow Schedule.
According to the 100% NATURAL Grow Style you don't have to regulate the pH and EC value of nutrient solutions when you combine Promix with Alga Grow and Alga Bloom.
Yes, technically this is possible. However, the airiness of Promix will make it difficult for the seeds or cutlings to absorb moisture. Therefore they will not develop as well and less quickly. The fibers in Promix also may hinder the seeds when they are growing out of the soil. Therefore you should rather use our Seeding & Cutting soil.
If you are an experienced 100% NATURAL grower and you want control over the amount of nutrients, then choose Promix. It will allow you to feed your own plants from day one. Plagron Allmix, Batmix and Royalmix are all soil mixtures that are prefertilised for 6 weeks. They are specifically created to combine with 100% NATURAL products. Choose Plagron Allmix if you grow in high temperatures, with high light intensity or in small pots. Choose Batmix if you want to go for the best quality and Royalmix if you want to go for the highest yields and a natural fruity flavour.
Yes, you can. Keep in mind that mineral basic nutrients aren't organic, though. The mineral nutrients won't cooperate as effectively with the soil life in the Promix. This means that you will have to monitor pH and EC values of the nutrient water when working with Promix.
alga grow
Yes. Although Batmix, Royalmix and Plagron Allmix are all pre-fertilised for six weeks, chances are that you'll notice yellowing after about four weeks. You'll have to fertilise with grow nutrients for a few more weeks. With Promix you'll start with Alga Grow from day one.
No, combined with our 100% NATURAL soils you don't have to regulate the pH and EC value of nutrient solutions.
Alga Grow can be stored in a solution for up to 48 hours. After this, Alga Grow may spoil. This is not bad for your plants, by the way. The Alga Grow will just begin to look unpleasant.
Our organic products will remain stable for 6 months after opening the product. Before opening, you can determine the shelf life by looking on the bottle for the black printed batch number. Mail this number to the Plagron service desk (servicedesk@plagron.com). They can tell you the best before date to use the product safely.
If a slimy sludge comes out of the bottle and or if you notice a smell of ammonia, the product has gone bad. Please note that this isn't bad for the plant! It's just a nasty sight and smell.
Yes, you can, once the mineral fertiliser is out of the substrate. With Lightmix that will take about a week, while with Growmix it will take about three weeks. As long as there are nutrients in the substrate, you'll have to monitor pH and EC values. You won't need to add nutrients. Once the pre-fertilisation is gone, you can start adding Alga Grow or Bloom and you won't need to monitor anything anymore. In the period between the two you'll only have to mind the pH. Alga Grow and Alga Bloom work perfectly well on 100% TERRA substrates. But Growmix and Lightmix are not organic and do not contain soil life.
alga bloom
No, combined with our 100% NATURAL soils you don't have to regulate the pH and EC value of nutrient solutions.
Alga Bloom can be stored in a solution for up to 48 hours. After this, Alga Grow may spoil. This is not bad for your plants, by the way. The Alga Bloom will just begin to look unpleasant.
Our organic products will remain stable for 6 months after opening the product. Before opening, you can determine the shelf life by looking for the black batch number. Mail this number to the Plagron service desk (servicedesk@plagron.com). They can tell you the best before date to use the product safely.

Alga Grow and Bloom work perfectly well on 100% TERRA substrates. But Growmix and Lightmix are not organic and do not contain soil life.
top grow box 100% NATURAL
This depens heavily on the type of plant. One Top Grow Box is suitable for 1m2. This can be five bigger plants or thirty smaller plants.
Combined with the mineral nutrition of the grow style 100% TERRA you need enzymes. Since the substrates in the 100% NATURAL grow style contain microbiological life that creates enzymes you don't need to add them. That's why the Top Grow Box 100% NATURAL includes Vita Race instead of Pure Zym.
Plagron Allmix, Batmix, Royalmix and Promix are specifically designed to combine with the Top Grow Box 100% NATURAL.
starter set 100% NATURAL
That depends on the length of the growth and flowering phase of your plants. It's possible you may have Alga Grow left, since the growth phase of plants is usually shorter than the flowering phase.
If you're looking for an even healthier plant, a more tasteful end product or a larger yield, you can combine the Starter Set 100% NATURAL with all additives from our UNIVERSAL range.
If you want to know more about our products or growing, you can always contact our servicedesk. This can be reached at servicedesk@plagron.com or through social media. As a starting grower, it might also be handy to order our free Startersguide. This can be done quick and easy on our website.
100% TERRA
Yes, you should regulate the pH value and EC values when growing with 100% TERRA. Terra Grow and Terra Bloom already adjust these values in your nutrient solution. However, tap water doesn’t have the same pH and EC value everywhere. We recommend a pH value between 5.5 and 6.5. You can adjust this with pH Plus, pH Min, Calcium Kick or Lemon Kick. The correct EC value differs for each plant species and its growth or bloom phase. Use our 100% TERRA Grow Schedule to find out which EC value best fits your plant.
We recommend using our 100% TERRA nutrients in combination with the specially developed substrates
Lightmix and Growmix. However, you can use these nutrients with all our substrates. Use our Product Selector
to find our which product best fits your situation.
growmix
A substrate with perlite holds water for a little longer. This can be an advantage when you're growing at a high temperature of high light intensity.
Growmix contains nutrients for the first three weeks of your growth. If your plants start flowering within this period you don't need Terra Grow. However, your plant needs Terra Bloom after the first three weeks.
lightmix
Lightmix is already pre-fertilised for one week. Start giving nutrients after one week.
Yes, Lightmix is made to be used with mineral nutrients. This means that the pH value and EC value affect the absorption of the nutrients. Therefore, it's important that you keep a close eye on it.
A substrate with perlite holds water for a little longer. This can be an advantage when you're growing at a high temperature of high light intensity.
Yes, this is possible. However, these substrates are very airy. This may complicate germination. We recommend using our Seeding & Cutting Soil to germinatio your seeds.
A seedling of 1-2 weeks old is ready to be planted in Lightmix.
terra grow
Yes, you should regulate the pH value and EC values when growing with 100% TERRA. Terra Grow already adjusts these values in your nutrient solution. However, tap water doesn’t have the same pH and EC value everywhere. We recommend a pH value between 5.5 and 6.5. You can adjust this with pH Plus, pH Min, Calcium Kick or Lemon Kick. The correct EC value differs for each plant species and its growth or bloom phase. Use our 100% TERRA Grow Schedule to find out which EC value best fits your plant.
Yes, this is possible. Terra Grow is a mineral fertiliser. This means its nutrients are directly absorbed by the plant. You can therefore quickly solve a nutrient deficiency in the growth phase by giving your plant Terra Grow as a foliar fertiliser. In this case, use a maximum of 2 ml Terra Grow for every litre of water.
Terra Grow can be stored for four days after it has been mixed with water. Do monitor the pH value, as this will probably start to slowly increase. Make sure that no organic products have been mixed into the solution, as they can start to spoil after just 48 hours. Also ensure the solution is kept moving (circulation pump) and that the tank is clean before you mix the solution.
terra bloom
Yes, you should regulate the pH value and EC values when growing with 100% TERRA. Terra Bloom already adjusts these values in your nutrient solution. However, tap water doesn’t have the same pH and EC value everywhere. We recommend a pH value between 5.5 and 6.5. You can adjust this with pH Plus, pH Min, Calcium Kick or Lemon Kick. The correct EC value differs for each plant species and its growth or bloom phase. Use our 100% TERRA Grow Schedule to find out which EC value best fits your plant.
Under normal circumstances, you use Terra Bloom from the start of the flowering phase. However, when using a prefertilised substrate it might be all right to start later. Use our Grow Schedule Calculator to find out when to start giving your plants Terra Bloom.
Terra Bloom can be stored for at least a week after it has been mixed with water. Make sure you monitor the pH value, as this will probably start to slowly increase. Also ensure that no organic products have been mixed into the solution. These can start soiling after just 48 hours. Keep the solution moving and make sure that the tank is clean before you mix the solution.
top grow box 100% TERRA
This depens heavily on the type of plant. One Top Grow Box is suitable for 1m2. This can be five bigger plants or thirty smaller plants.
When growing with 100% TERRA your plants need extra enzymes. If you're growing with 100% NATURAL these aren't required. To ensure your plants receive enough enzymes the Top Grow Box 100% TERRA comes with Pure Zym instead of Vita Race. Using Vita Race with our 100% TERRA grow style is fine.
We recommend combining Lightmix or Growmix when using the Top Grow Box 100% TERRA. These substrates
have been specially developed to be used with all 100% TERRA nutrients.
starter set 100% TERRA
That depends on the length of the growth and flowering phase of your plants. It's possible you may have Terra Grow left, since the growth phase of plants is usually shorter than the flowering phase.
If you're looking for an even healthier plant, a more tasteful end product or a larger yield, you can combine the Starter Set 100% TERRA with all additives from our UNIVERSAL range.
If you want to know more about our products or growing, you can always contact our servicedesk. This can be reached at servicedesk@plagron.com or through social media. As a starting grower, it might also be handy to order our free Startersguide. This can be done quick and easy on our website.
100% COCO
Yes. If you use 100% COCO grow style you should adjust the pH and EC value of your nutrient water to somewhere between 5.5 and 6.5 after the products have been mixed.
Drainage is essential for the best results and the fewest problems. If you prefer to grow without drainage, it is better to use potting soil instead of 100% COCO substrates.
plagron hydro cocos 60/40
The mixture of coconut fibre and clay pebbles combines the best of two substrates. The coconut is completely rinsed and buffered, which results in a forgiving substrate that will balance out problems with the pH value. The clay pebbles make the substrate more airy and give it improved drainage. Seperate coconut or clay pebble substrates would not combine these qualities.
Plagron Hydro Cocos 60/40 is part of the 100% COCO grow style. This means we advise the use of Cocos A&B as your basic nutrient. Hydro A&B will work, but it's not our recommendation.
cocos premium
No. Cocos Premium has already been rinsed and buffered, in accordance with the highest standards. You can start potting your plants immediately.
You should start watering with a nutrient solution of Cocos A&B from day one.
After a bad harvest, you should take into account that part of the nutrition dosed has not been absorbed by the plants. This means that the substrate cannot be re-used. It is best to change the Cocos Premium in any case after six months.
cocos slab
No, the Cocos Slab has already been rinsed and buffered in accordance with the highest standards. You can start potting your plants immediately.
Depending on your tap water quality, the pH buffer in our Cocos Slab will be used up quicker or slower. The Cocos Slab can be used for growing for six months at least without any problems.
You should start watering with a nutrient solution of Cocos A&B from day one.
After a bad harvest, you should take into account that part of the nutrition dosed has not been absorbed by the plants. This means that the substrate cannot be re-used. It is best to change the Cocos Slabs in any case after six months.
cocos brix
We advise adding 4.5 litres of water per Cocos Brix. This creates 7.5 litres of coconut substrate.
Yes, the quality is identical.
Depending on your tap water quality, the pH buffer in our Cocos Brix will be used up quicker or slower. Cocos Brix can be used for growing for six months at least without any problems.
After a bad harvest, you should take into account that part of the nutrition dosed has not been absorbed by the plants. This means that the substrate cannot be re-used. It is best to change the Cocos Brix in any case after six months.
cocos a & cocos b
Yes. If you use 100% COCO grow style you should adjust the pH value to between 5.5 and 6.5 after the products have been mixed.
100% COCO is a hydroponic growing method. With hydrological methods, you give more of all the nutrients than the plants need. What the plants don't use drains away. Cocos A&B contains enough growth nutrients like  nitrogen and enough flowering nutrients such as plenty of phosphorus and potassium. It also contains magnesium and calcium. As the plant only absorbs what it needs, you can provide flowering nutrients in the growth phase which the plant doesn't actually use and vice versa. This is why there is no separate growth and flowering product for hydrological fertilisers.
The nutrient solution can be stored for between four and ten days depending on the hygiene in the growing room and the water tank. Make sure that no organic products have been mixed into the solution, as they can start to spoil after 48 hours. Monitor the pH value daily, as this will probably start to slowly increase.
plagron cocos perlite 70/30
The mixture of coconut fibre and perlite combines the best of two substrates. The coconut is completely rinsed and buffered, which results in a forgiving substrate that will balance out problems with the pH value. The perlite makes the substrate more airy and gives it improved drainage. Seperate coconut or perlite substrates would not combine these qualities.
Plagron Cocos Perlite 70/30 is part of the 100% COCO grow style. This means we advise the use of Cocos A&B as your basic nutrient. Hydro A&B will work, but it's not our recommendation.
100% HYDRO
Yes, our 100% HYDRO products work with all watering systems. Deep Water Culture is no exception.
No, we strongly recommend measuring the pH and EC values when growing with 100% HYDRO. With this grow style, these values can change rapidly. An incorrect value may also lead to a botched harvest. Therefore, always make sure you are aware of the pH and EC values, so you can adjust them if necessary.
There are multiple reasons for this. As a grower, you are responsible for the pH and EC value. You can also compensate an incorrect pH or EC value within an hour by flushing your substrate. Next, bring the pH and EC value in your substrate back to the correct level. This way, you can closely match your chosen plant's needs.
In the 100% HYDRO grow style you are responsible for determining key factors such as the pH and EC value. If something goes wrong with this, you might end up with a botched harvest. Make sure you have enough experience measuring the pH value, calibrating  pH meters and adjusting the pH value in your nutrition tank. When growing with 100% HYDRO, irrigation systems are commonly used. These also requires experience, as an incorrectly set timer can cause plants to dehydrate or drown.
euro pebbles
Euro Pebbles have already been rinsed. However, dust is formed during transport, so it is best to rinse Euro Pebbles before use. You will also want to give nutrient feed water with the correct EC and pH value before planting.
It is almost impossible to give too much water on Euro Pebbles, as the gaps between the pebbles are very large. Instead, make sure you give enough water. We recommend watering at least twice an hour, including during the night. Use a timer on your irrigation system for this. 
You can use Euro Pebbles for many years. To do so, first remove any old plant debris. Next, soak the Euro Pebbles for 24 hours in a solution of Pure Zym and water with a pH value of 5.5. Then rinse them with a nutrient solution of 1 ml Hydro A&B per litre water. Make sure this water has a pH value of 5.5.
hydro a & hydro b
Yes, you should regulate the pH value and EC values when growing with 100% HYDRO. Hydro A&B already adjust these values in your nutrient solution. However, tap water doesn’t have the same pH and EC value everywhere. We recommend a pH value between 5.5 and 6.5. You can adjust this with pH Plus or pH Min. The correct EC value differs for each plant species and its growth or bloom phase. Use our 100% HYDRO Grow Schedule to find out which EC value best fits your plant.
Hydro A&B can be stored for four days after they have been mixed with water. Do monitor the pH value, as this will probably start to slowly increase. Make sure that no organic products have been mixed into the solution, as they can start to spoil after just 48 hours. Also ensure the solution is kept moving (circulation pump) and that the tank is clean before you mix the solution.
UNIVERSAL
No, the products from the category UNIVERSAL are additives. The UNIVERSAL product are additions to substrates and basic nutrients from the 4 grow styles.
The UNIVERSAL substrate complements Bat Guano, Mega Worm and Supermix are suitable for organic growing. The same goes for the enhancers Vita Race and Vita Start and the pH controller Calcium Kick. These products all carry the Control Union quality mark. This CU-logo can be found on the product packaging and our website. This logo means that the product is suitable for organic farming according to regulation (EU) 837/2007 .
Yes, you can combine the UNIVERSAL products endlessly with products from the grow styles 100% NATURAL, 100% TERRA, 100% COCO and 100% HYDRO.
power roots
You ideally want the plant to develop enough roots early in the flowering phase, so the plant can utilise its energy to produce flowers. Stop giving Power Roots from the third week of flowering.
A nutrient solution with Power Roots can be stored up to 48 hours after preparation. This is because Power Roots contains many organic ingredients. In a nutrient solution, these can spoil after 48 hours.
pure zym
A nutrient solution with Pure Zym can be stored up to 48 hours after preparation. This is because Pure Zym contains many organic ingredients. In a nutrient solution, these can spoil after 48 hours.
Yes, that's possible. Combining enzymes with Alga Grow and Alga Bloom won't do your plants any harm.
vita race
Yes, Vita Race can be combined with every grow style, provided that you spray Vita Race on the leaves. Vita Race works most efficiently as a spray.
The leaves mainly absorb nutrients during the day. This makes the start of the day the best time to spray Vita Race. Your plant can then absorb nutrients the rest of the day.
A nutrient solution with Vita Race can be stored up to 48 hours after preparation. This is because Vita Race contains many organic ingredients. In a nutrient solution, these can spoil after 48 hours.
Vita Start is an organic vitamin spray for seedlings, cuttings and mother plants. It contains nitrogen and potassium. Nitrogen enhances growth of the plant and potassium ensures activities of stomata. Vita Race is an organic foliar feed for mature plants. It contains phosphorus, potassium and iron which accelerate plant growth and flowering as well as the production of chlorophyll.
start up
No, we advise against using Start Up if you grow hydrologically on coconut or clay pellets. Do you grow with peat substrates from the 100% TERRA and 100% NATURAL grow styles? Then you can use Start Up just fine. If you use Start Up you do not need to use Terra Grow, Alga Grow, Power Roots or Vita Race. The necessary nutrients from these products are combined in Start Up.
A nutrient solution with Start Up can be stored up to 48 hours after preparation. This is because Start Up contains many organic ingredients. In a nutrient solution, these can spoil after 48 hours.
sugar royal
Yes, this is possible. Sugar Royal does not work the same as the flowering stimulator in Green Sensation.
Yes, you can spray the leaves with Sugar Royal. Combining Sugar Royal and Vita Race us possible. However, we advise not spraying the leaves and flowers with these products after the third week of the flowering phase. Otherwise, these products may influence the taste of the end product.
A nutrient solution with Sugar Royal can be stored up to 48 hours after preparation. This is because Sugar Royal contains many organic ingredients. In a nutrient solution, these can spoil after 48 hours.
No, there is no sugar in Sugar Royal. Sugar Royal contains a high concentration of amino acids.
Due to the accelerated and increasing uptake of nutrients, the sugar percentage in the fruits will also increase. This results in a sweeter tasting fruit. The sugar percentage is expressed in the Brix value. You can read more about this in our Grow Topics.
vita start
Yes, but only if you grow on a peat substrate. Keep in mind that the nutrients in Vita Start are absorbed less quickly through the roots than through the leaves.
Vita Start stimulates the plant to branch out. This quickly creates extra cuttings on the mother plant. Vita Start also boost the plant's resistance and creates extra vigour.
A nutrient solution with Vita Start can be stored up to 48 hours after preparation. This is because Vita Start contains many organic ingredients. In a nutrient solution, these can spoil after 48 hours.
Vita Start is an organic vitamin spray for seedlings, cuttings and mother plants. It contains nitrogen and potassium. Nitrogen enhances growth of the plant and potassium ensures activities of stomata. Vita Race is an organic foliar feed for mature plants. It contains phosphorus, potassium and iron which accelerate plant growth and flowering as well as the production of chlorophyll.
fish force
Yes, but only in the growth phase. Be aware of a pungent smell of fish.
We recommend using Fish Force in the growth phase. This is because Fish Force is rich in the vitamins, amino acids and nitrogen a plant needs in this phase.
Yes, if used as a foliar feed. Adding it to your nutrient solution is only possible when growing on our peat substrates.
A nutrient solution with Fish Force can be stored up to 48 hours after preparation. This is because Fish Force contains many organic ingredients. In a nutrient solution, these can spoil after 48 hours.
pk 13-14
Yes, you should regulate the pH and EC value when growing with PK13-14. In mineral fertilisers, the pH value determines the absorption of nutrients by the plant. However, tap water may differ in pH and EC values per region. We recommend a nutrient solution with a pH value between 5.5 and 6.5. You can adjust this pH value with pH Plus, pH Min or Lemon Kick. The correct EC value differs for each plant species and its growth or flowering phase.
Yes that's correct. PK 13-14 is transparent.
ph plus
Yes, this works. However, this will alter the NPK value of your fertilisers. We therefore don't recommend doing so.
The amount of PH Plus in your solution depends on the water quality and how much nutrient is used. This constantly changes the amount of PH Plus required. Use a pH meter or pH strips when using PH Plus.
ph min
Yes, this works. However, this will alter the NPK value of your fertilisers. We therefore don't recommend doing so.
The amount of PH Min in your solution depends on the water quality and how much nutrient is used. This constantly changes the amount of PH Plus required. Use a pH meter or pH strips when using PH Min.
lemon kick
If you grow organically, you don't want to use phosphoric acid or nitric aci. This kills your important soil life. Furthermore, Lemon Kick doesn't change your NPK value, while phosphoric or nitric acid does. Lemon Kick also doesn't affect your soil life.
Yes, with Lemon Kick you decrease the pH value of the nutrient water without affecting the soil life.
A nutrient solution with Lemon Kick can be stored up to 48 hours after preparation. This is because Lemon Kick contains many organic ingredients. In a nutrient solution, these can spoil after 48 hours.
calcium kick
No, Plagron peat substrates already contain enough calcium for at least one cycle. You can use Calcium Kick to upgrade soil after a grow or to create a stable pH value in a coco substrate.
Yes, especially if you want to re-use your soil after growing. Tp upgrade your soil, use 2.5 to 5 kg Calcium kick per 1000 litres of potting soil. Calcium Kick increases the pH level of the soil after growing, so the plants can absorb all the necessary nutrients.
mega worm
The effect worms have in your soil has already taken place in Mega Worm.
No, Mega Worm contains little directly absorbable nutrients. Mega Worm does contain a high level of soil life. This soil life converts organic components in your soil into nutrients that the plant can absorb.
Yes, you can use Mega Worm to stimulate soil life. You can combine it with Supermix to optimise the development of the plant. We recommend also using Calcium Kick to adjusting the pH level and  Bat Guano to bring enough nutrients into your soil.
Yes, if you want to improve the quality of the outdoor soil you can use Mega Worm.
supermix
Yes, you can use Supermix to upgrade your peat substrates. Unused, these substrates are prefertilised. This means you don't need to use Supermix for your first grow on any of these substrates.
No, Supermix can only be added to peat substrates..

bat guano
Yes, you can use Bat Guano to bring enough nutrients into your soil. Use Mega Worm to stimulate soil life. You can combine this with Supermix to optimise the development of the plant. Also use Calcium Kick for adjusting your pH level.
This depends on many factors, such as plant health, size and species as well as environmental factors. Our grow experts are more than happy to give you a fitting answer. You can reach them on social media or at servicedesk@plagron.com.
Yes, this is possible. Bat Guano is a high quality, organic fertiliser for your all plants.
perlite
Yes, Perlite is a fully hydrological substrate in its own right.
Yes, Perlite is an excellent product if you want to make your substrate airier or increase the drainage.
No, this won't hurt. Perlite is a volcanic rock and will not pollute your soil.
Yes this is possible. However, we do not advise it. Seeding and Cutting Soil does not contain enough nutrients for a whole grow cycle. The fine structure is also best suited to the development of young plants.
seedbooster plus
Dissolve 7 drops Seedbooster Plus in 1 liter of water. Then put your plant's seeds in this solution.
A good method is to first soak the seeds for 12 hours. Use water that's 23 degrees Celsius and add Seedbooster Plus to it.
Give Seedbooster Plus up to one week after rooting to protect your young plants.
seeding & cutting soil
Seeding and Cutting Soil has a low EC value. This promotes the germination and rooting of young plants. The fine structure of Seeding and Cutting Soil ensures that roots can develop optimally.
Yes, this is possible. However, we do not advise it. Seeding and Cutting Soil does not contain enough nutrients for a whole grow cycle. The fine structure is also best suited to the development of young plants.
After two weeks, seedlings or cuttings are well-rooted and ready to be transferred to another substrate.
seedbox
If you follow the instructions of the Seedbox and the seeds are of good quality, the seeds will germinate within one week.
Our coco plugs are buffered. Nevertheless we advise regulating the pH value when growing on coco. This way you ensure optimal uptake of nutrients.
green sensation
Yes, this is no problem at all.
Green Sensation is a 4-in-1 product. With Plagron Green Sensation, you do not need to buy separate PK fertilisers, enzymes, enhancers or boosters. This is because Green Sensation contains all these products in one bottle.
We do not believe in over-fertilisation with phosphorus and potassium. This won't benefit the quality of the plant.
Green Sensation is not an organic product, but also won't disturb your soil life. You can safely use it when growing organic.
grow schedules
Every grow style requires specific products and dosages. For example if you choose 100% NATURAL you need to follow the instructions in the 100% NATURAL Grow Schedule.
The development of seed to seedling takes approximately one to two weeks. It is important that the plant is well rooted and has a healthy leaf. From this moment the growth phase begins and you can consult our Plagron Grow Schedules. Download the Grow Schedules here.
