A balanced diet.
Plants can use a whole list of elements that positively influence their growth, the generation of chlorophyll and other important processes. In the growth phase, a plant needs these elements in other ratios than during bloom. Luckily you don’t need to worry about this if you have good basic nutrients. Plagron’s Alga Grow is a good example: it’s tuned to the requirements of a plant in it’s growth phase. Basic nutrition is available in all kinds of forms and content sizes. Plagron’s products are liquid and pretty concentrated. In other words: you need to mix it with water before giving it to your plants.
Alga Grow has a concentration of 1:250. This means you need to add 1 ml of nutrients to 250 ml of water. If you translate this to a litre of water you need to add a maximum of 4 ml of Alga Grow. With every additional litre of water you add another 4 ml.
- Start with the amount of water you need. Most buckets or watering cans have an indicator of how much water is in them.
- Measure out the correct amount of Alga Grow and add it to the water. (For example: 12 ml to 3 litres of water.) Stir the mixture with a wooden stirring tool.
- Once you’ve mixed the nutrition and water well, you can give the nutrient solution to your plants.
On prefertilised substrates.
Of course, if you are using a prefertilised substrate in a pot, like Batmix, you don’t need to add grow nutrients for the first six weeks. After this period you might notice a color change in the leaves. If these start to yellow a little bit, you need to start with the basic nutrition.
