help wanted

i have 8 plants unknow of there sex yet, all soil grown in a 2x2 space it has 4ft of hight for it to grow vertically and very good utes and ventaltion, im 4 days in to flowering and want to know if i can use the 2- 26 watt soft white cfls and 1- 250 watt mh for my flowering stage. by the way whats a guess on about how big of a yield ill get and potency from this set up

That's allot of plants for such a small space. My space is lik 2.5 by 6 and I have only three plants bringin around 2 zips a piece. You can do the MH + the CFL's. Won't hurt nothin.
