The grow room is a tent that is 8x8. 4 (1000watt Hps) 2 (250 cfls) n 2 (125 cfls) the cfls are for under growth. The total wattage is 4000 on the Hps. The 250cfls convert to around 1000watts per bulb in incandescent watts and the 125cfls convert to around 300watts per bulb. For a grand total of around 6-6500 watts of light!!!! That is around 90-101 watts per ft!! I have three mothers in 10 gal smart pots n 14 clones off the three mothers in 5 gal smart pots for a total of 17 plants. Mothers are coming in around 3'5"-4' tall and 5' around. All the clones are around 3' tall and 4'+ around. Mothers were veged for three months n clones for two months. Just wondering on a rough estimate of how much i should expect. It is my first time trying this high of wattage. Only problem I am having is with keeping the temp where I want it.

Those cfls don't convert to that much watt. I have 300w cfl bulbs in my clone/seedling box and they only use actually 68w. The 250w is the incandescent conversion. But you still have a lot of light and depending on your genetics you should get at least a few pounds. Keep them ladies happy and they'll reward you

So that's only 750 watts..you don't use conversion watts but actual watts when growing with CFL's which is 750 actual watts !

which is why the post says 5k watts.. But if you convert it into incandescent it would equal around 2600 watts in incandescent between all four of the cfls. For my watts per ft.

Okay I'll just do it in lumens so there is no conversion needed. That would be over 8000 lumens per sq ft. 120k lumens per Hps 10k lumens per 250cfl n 7k lumens per 125cfl... So 480k + 20k + 14k = 514k / 64sq ft = 8k lumens per sq ft. I was just trying to give a perspective so people would understand how much light I'm feeding these girls. For a better estimate. I'm just trying to prepare for the harvest. Hours, supplies needed n help I will need to trim ect...

NOW you're cooking with gas...always figure by lumens and not watts...8000 watts per square foot is pretty decent !

I'll take a guess on this one, because it think its gonna be an eye opener for the OP. I'm gonna guess about 900 grams.

No matter what type of lights those are, they seem really far away from your plants, and like there is a ton of light hitting the floor. Just my 2 cents. Also did you defoliate these plants, there doesn't seem to be very many larger fan leaves?
