I am using rockwool cubes for my grow in my hydroponic system and needed some opinions/advice. Once i germinate the seed and place in the rockwool should i leave the rockwool out of light for a couple of days and let the seed natural grow a stem. I would pre soak the rockwool before i put the seed in. Also how effect is rockwool cubes in a hydroponic system. Does it really help root growth?
