Are supplemental cfls worth it?

I currently have 30 plants in a 4x8 homemade box with 2 1000w mh bulbs. 12 of them are feminized big buddha cheese, and 18 of them are mr nice critical mass and they were not feminized so at a 50% female ratio, I should end up with approx 21 plants growing in the 4x8 area. I was wondering if I add twenty 40 watt cfl lights @ 2600 lumens to my under growth, if it would considerably add to my yield? or maybe just add another 1000w or something? all input is greatly appreciated, thanks.

by the way ive been vegging for 6 weeks so far, the tallest of them is about 17-18 inches tall. i started the cheese about 2 weeks after the CM though so they are a little smaller. havent started flowering yet because i was thinking of getting this supplemental lighting before i make the switch to 12/12. room temp stays at about 76, i use foxfarm ocean forest soil, foxfarm nutes. 3 gal pots filled about half way up then folded down, should i also transplant to 3 gals that are full?
 
Yessirrr.. i added clf's to my hps room to mix up the color spectrum and increase lumens. Not to mention they use very little power and no heat.

If you have 20 cfl's x 2,600 = 52,000 lumens. I would think that should increase your production!

But, if you are already over 8-10,000 lumens per sq. ft.... it may be a waste

Yeah but if you were to put them under the plants or in spots that aren't getting alot of light I think that would increase yield for sure. CFL's can get super close to plants. I have mine inches away. I like the horticulture grade ones better BTW. 125 watts and up.

I agree, put them below the canopy if possible... thats how mine are :)
