can you still flower with 8500 lumens or do you need the 10000 to even start the flower period?
small question on lumen's.

just like he said the more the better. i used 28 on my first grow and this one i am doing now i am going with 40 to 60 26 watt cfls. good luck with your grow...

Yah get a hps man much more efficent, cfls alright for proximity but dude thats a mess with all that.
LOLOL....
Got you beat with 150,000 for 5 plants
But lumens are a horrifically shit measurement of lamp output when it comes to plants; it's almost meaningless.

i really like the cfls with the small space grows. im sure with the money ive spent i could of bought a hps or mh system. but when you are on budget and dont want a huge power bill cfls are great. i have had alot of fun with my two grows with cfls. i just want to see what i can do with 35 or 40 of them. i think each grower has their prefrence on what they think works and what they like to grow with and i really like what i have done with cfls.
Wow, just did the math on mine - two 600w hps on my 11 plant scrog - 180,000 Lumen. No wonder the widow is a chest high hedge of buds !

i would say that he needs to get some more light forsure!!!!
That is so true!!! Lumens don't mean diddely except as a rough guide to how many square feet you can light up! A "plant" can be as small as a Daisey, or as big as a Christmas tree! A square foot is always 144 sq. inches!
More importantly, lumens are a measurement that was designed to rate how bright something looks to human eyes, which are most sensitive to green light; exactly the opposite of plants. So you can design a lamp with a huge lumen rating that is effectively useless for growing plants. One that gave out pure green light would be an example. It could score a massive lumen rating and be worthless for plants.
Hydroponic guys use the same trick. If they get a bulb to output more energy closer to the green spike, so around the yellow region also, the lamp will score a higher lumen rating per watt that goes into it. It'll also be worse for growing with.
PAR watts are better, which measure the amount of watts emitted through the visible band without any weighting of one color over the other. They're still easy to manipulate to make one bulb seem much better than another when they're just about the same thing.
