Growing without problems on pre-fertilised soil

Plagron Growmix is a mix of the finest, carefully selected types of peat. The addition of various types of fibre and perlite results in a lightness and oxygen level found only in Plagron quality substrates. The abundant presence of unique Plagron worm castings ensures vigorous plant growth and increased water retention. The nutrients that have been added to the Growmix consist of a carefully selected combination of fertilisers which meet all the needs of the plant during the first three weeks. Growmix is the perfect base for optimum growth and blooming and delivers the quality Plagron has been supplying for years. Growmix produces the highest yields when used with Plagron Terra Grow, Terra Bloom and the additives from Plagron. Growmix: also available without perlite.

  • Growmix is prefertilised for 3 weeks.
  • Frequently asked questions about Growmix
    Yes, you can. Growmix has been specifically developed to be combined with 100% TERRA and 100% NATURAL grow styles. However, Growmix is not 100% organic in it's own right. Our Alga Grow and Alga Bloom products work very well on Growmix. If you use Alga Grow and Alga Bloom on Growmix, you do not have to adjust the pH value. However, if you use 100% TERRA grow style, you should adjust the pH value.
    No. Growmix contains nutrition for the first three weeks, so if your plants start flowering within this period you do not need to use Terra Grow.
