Actually I am just about to harvest my 1st grow in my Hydro/Cab and never really had any big probs to deal with. No pests what so ever, really the only 2 issues I had was 1) move cabinet away from AC since intake was pulling cool air directly into cabinet and plants didnt like being that cool hehe and 2) a little bit of algae on the top of the rockwool cube but fixed that with a cube cover. just got our 30x magnifier today so get to take our fiest look in about 40 mins!! YEA!!!
