GreenHaze Grow Overview GreenHaze GROW is a twin pack alternative to IONIC. This solution was initially developed for NFT systems, which is a very demanding application. It has proven its worth over many years and is used now in many different cultivation systems. The GROW solution is properly formulated to support vegetative growth and will deliver vigorous plant growth and strong, healthy roots. GreenHaze performs well in both hard and soft water but, like all twin-packs, it will need regular adjustment of the pH.
