I would start in rockwool but you will be alright. We all must give it a try and see what works for you. Sounds good, you been reading that's a good start.

Remember no nutes for 2 weeks at least and then bring it up slow.

GH 3 part is good . I used the lucus formula. Don't forget the Cal-mag plus. It's a must for hydro no mater what nutes you use. Superthrive is good too, it's a B1 complex.

First Grow - when should jiffy pellet seedlings be transported to rockwool I have recently germenated several seeds and planted them in jiffy pellets. Once I see a sprout should I immediately put the pellet in a 4" rockwool cube? I'm also realizing the small ready to grow hydro system I've had for a while but never tried to use until now will really only fit jiffy pellets/1" cubes, so I'm going to build my own 3'x2'x4" tray/resivour system soon. If my seeds sprout before I can have it ready, can I water them manually 3 times a day with a ph balanced half strength Rating: 5
