ok, that is a hydro system, you need to 1) ph the water in the rez(tank) to 5.6 to 5.8. dont let it go over 6, you'll have bullshiit. 2) change the water every 3 days because its a small tank. 3) use nutes at 1/4 strength for the first 2 weeks, then gradually up the nutes 4) it's hydro, somethings going to fuck up so you're doomed unless you're a pro
drop at a time then test. you can wait till 2 week if you want
they dont have a computer parts store? you could get them cheap there
does the AG have an air pump?
is there any bubbling in the rez? if not you need an air pump... see with hydro youre gonna have to keep buying shit
where r ya? dont let that seedling stretch! how's the english class?
