I wish I could agree with your comments, but based on my grow, 0 roots have been able to grow outside of the plastic bag. We are 22 days into the grow(auto plant) with it’s first set of real leaves that are developing which are still tiny babies, the cotyledon leaves started going yellow and then have now dried and died. It’s not a ph problem and and nor nutrient, it’s a igrowcan and if you know of them it has a premix and then one for bloom stage.
