I'm with Dutch Pimp...I've heard lousy things about digital ballasts. I've never used one, but I've read in several places that there have been problems. My guess is they'll have it figured out in a couple of years...but, still, it's a concern. Like I said, I've never used one...I'd check around this site and google about potential problems.

The electric bill difference between a 250w and a 400w lights won't be huge...but you'll need more ventilation and fans. That will add to both energy and potential stress. A 400w is, to an extent, overkill in a 6 sq. ft. area. But that area is stretching what you can cover with a 250s...if you use the whole area. You say you're only going to grow 2-3 plants? Unless they are seriously huge, you won't use more than 4 or 5 sq. ft. If you go 24? x 30?, a 250w is fine for that. That's more or less my grow space, and I can get four medium sized plants into it.

Btw...you'll still be moving your lights pretty often, at least for a few weeks. The difference between a plant being comfortable and getting some heat stress is pretty small with HPS lights.
Roughrider Reviewed by Roughrider on . 250w Floralux or 400w system? Hey guys. I'm doing my first grow right now with cfls and I hate it. I'm tired of moving the lights around everyday. I swear I move them every single day cause my babies are moving up fast. I decided I'm going to go ahead and get some better light. I saw that HTG had a Floralux 250 watt HPS/MH system for $229. But today when I went to their site they had a 400w hps/Mh system for $165. Now I like the price of that one. My question to you guys, would the 400w system be overkill for a 3'x2' grow Rating: 5
