All systems, All substrates
The application of Dutsch Formula goes beyond hydroponic systems as it can be used for all substrates. All growers, including coco and earth* growers, have seen a substantial increase in their harvest by using Dutsch Formula.
(*Earth growers should decrease the concentration by almost a half)

GROW
The recommended combination of Dutch Formula 1, 2 & 3 (fig. 1) during the 18 hour vegetative stage is the best guarantee for high quality results and strong, healthy plants with lush green leaves. 
 
Dutch Formula GROW creates the ultimate conditions for crop production during the 12 hour stage. The application of GROW should be stopped between 21 and 30 days after your plants have entered the 12 hour flower phase.
