200w CFL vs 150w HPS

Thanks, great info.
Check out the link to my grow log below, it has just a few pictures where you can see the lights. All bulbs have reflectors and all bulbs are 1 to 3 inches above the tops. Also, the walls are lined with reflective insulation material and are very close to the plants so the light doesn't have to travel very far when reflected. Not sure what else I can do, I guess I feel pretty good about it, especially with the continued LST that keeps all main tops very close to the lights.
Still, if I could really get 25-50% more by using a 150w HPS which actually uses slightly less power then that sounds like a bargain and I will probably do that eventually.
Anyway, in a month or so I guess we'll know exactly how much I got. At least pretty close though I don't own/need a scale.

Lastly, I'm planning for my next grow to be in a Hempy Bucket (passive hydro). I wonder how that would do with the 150w HPS / Hydro combination!
If you don't know what a Hempy grow is check this out or just Google "Hempy Grow".

Hempy Bucket eh, thanks for the great link...ima give that a try also

peace

You really need at least 2500 lumens a sq. ft. to grow decently; over 4000 is a lot better. A 150w HPS, like I said, will produce about 15,000 lumens. You could get a marginal 6 sq. ft. grow with it, or a pretty good 4 sq. ft. grow with it. 200w of CFLs will probably give you about the same amount of lumens. The CFLs will be cooler so you will have less problem with heat; they are less efficient, so you won't get the light depth into your plant.

Hey Bro, Great information and i am new to the site. I just want to get your opinion on a grow system i have (first time grower). I have a bubbleponic system in a 32X64X24 grow hut i am running two 6" fans with 455 led lights rated at 54 watts and 2 23 watt cfls. (100watt replacments). i am running about 80 degrees and about 60% humidity. I havent planted yet due to i want everthing perfect and running smoothly.(i have 6 5 inch plants outdoors right now) im going to transplant soon and was wondering if my lighting if enough to produce good plants. Any info would be greatly appericiated. thanks alot

Just a quick question for you are those 6" fans inline duct fans, venting out of the tent or just oscilating fans circulationg the air?if they are vented out and your geting 80 degree temp with nothing growing or running. you can expect your temps will definately rise once you do get the grow going.
