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.

My plants have a short growth phase. When using Growmix, should I give them basic nutrients during this phase?

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.
