High Pressure Sodium, though I suggest buying a multi-spectrum bulb when your MH burns out.
haha thanks i just got my light set up and for $60 off cL
Yeah the blue ones would be 6500k those are for veg, you need the big 68 watt 2700k for flowering, a few of them actually and you should be good.i grow medical so i was wondering about light what. I have 55 clones right now and i can have 24 in flowering so what wattage would be suitable for those plants or would i need like 2 lights ??
I have 2 100w cfl's and 3 60w cfl's from lowes in there too
the blue spectrum..... are those available at depot stores???
super blue goes into regular hps ballastHps all day! if your going for a dual bulb mh & hps make sure your ballast complies! BOOOOOM
You realize he has a 400w M/H a foot above those CFL's? And in reality those cfls are creating more shade than helping... lolI would suggest sticking another CFL on each of those boxes, but this is optional.
