CFL vs. HPS

[Opie Yutts]

Is that only in Cali?

I don't know if it's in CA or not, but it's in at least one other place.

is it true that the same amount of light from CFLs will get hotter than the HPS? I thought that was the advantage of CFLs...? maybe it's just conflicting Opinions ... so would i be better off with a 150 or 250 HPS?

I don't know about that, seems not right though. I'm thinking about my 12 CFL in my bud section that are something like 26 watts each, but are supposedly equal to a 1200 watt incandescent. I assume for comparative reasons that's supposed to be the same as a 1200W HID light, not sure. I do know how hot my 400W gets, so I can imagine how hot a 312W would get (12x26W). I'm fairly certain that 312W of CFL runs cooler than 312 of HID, and that's supposed to be worth 1200 watts of other light. I've never tested it though, and wouldn't be too surprised to hear they were close.

I do know that I have much fewer temperature issues when I grow in enclosed places with CFL. Actually, I guess that would be about none. Just throw a fan or two on the grow and that's it. No ducting. No cutting holes to the outdoors. No huge, noisy fans or electricity bills. Just make sure you use the correct spectrums and you'll get a good harvest. True, nothing like the same wattage of HID, but I'm beginning to think that little bit of extra yield is not worth the extra hassle and cost. Man I can't believe I'm saying this.

Opie Yutts Reviewed by Opie Yutts on 02-18-2008. CFL vs. HPS I'm currently planning my grow, which will be in an attic. It's not my house so I can't exactly start drilling holes everywhere, but I think regardless it's a little drafty so it may ventilate itself! Haha. There is a window which I could use though. But my question is: CFL bulbs REALLY are attractive because of how low their watt usage is - but can you really go the whole grow with CFL bulbs? I would like some tips on this, as well as the pros and cons. If an HPS is just simply better, then Rating: 5
