After 2 runs of a drip system and having shitty overwatered product. I decided to hand water, not only that but i only water every other day, less chem cost, now the rez. Will last 2 weeks. Also with rockwool it needs to dry out a bit so the roots will go hunting for water, "bigger roots, bigger buds" im using super veg with some additives, b-vit, hygro. Ext....
For bloom sincibloom with all kinds of extras... (depends on the strain...kinda...)
as far as gnats, if its only gnats, i would bomb the room after a 5day 3 feed cycle of "go-nats, or ngnatrol" for root aphids there is only 1 cure, nematodes......!!!!!!!!! And they kill everything...!!!! But the plants.... I aded a bomb to get the lil fuckers as they ran off my tables trying not to be destroyed by the "todes"
