well all i can tell you is that the lights i use are two F40T12 Cool Light Plus, and there on 13h a day. I do this cuz i got 2 plants finishing off and ready for harvest soon. and the other is to slowly increase light over a period of time so it times itself with the outdoor light of april so it can be an outdoor plant in the spring.
thats it....
ohh i water by hand, no hydro no pump nothing. just a shop lamp and a blower.
