my bubbler skills are low too, like 10% I've tried a couple batches n they rot easily its because i was giving them a touch of nutes i feel like just plain water would be easier on them. i use boomerang comeback usually, i have 1 with roots out of 3 right now from a week ago and even then the roots are coming out of a somewhat rotting stem. I'm gonna try just phed water n letchu know on next attempt
