Meters are OK, just make shure you get calibration solution to check them from time to time.. Plants looking good just get the lights as close as you can. Fluro's will not burn them and it keeps the streching down.

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
