dribbzzyanswered grow question 4 years ago Thanks for the info. Im actually not using soil just yet, for about a month they will be in rockwool cubes so hence why i want to use root enhancers as quick and safely as possible, i will be using a light compost tea if they show signs that they need anything, the soil is taken from the area i will grow them at and i will be adding amendmants to it, but for now mineral water will do for the seedling phase but really am just curious about how quick i can start applying root enhancers?
