Coming to the end of my cfl grow and wondering if I can get away with hps...
My space in short, 90cm height and 22cm is taken up by the pots. Doing 2 at a time.
Looking at charts they can be as close as 4 inches in the optimal range. I'm wondering if 1 (or 2) of these 150hps lights would be better than 2 200w duel cfls?
Temps may rise but winters coming and tents going into a garden cabin so I imagine it'll get pretty cool in there (I plan on insulating the hidden space with celotex to try and lower temp swings).
