sound good, but make a profit? Sorry, but i dont see that happening, no offense, its just the truth and I dont think counting on it is gonna help you upgrade and then finding out it really isnt would be a sort of buzzkill or downer or whatever when you realize it later. another $20-30 in cfls will make a big diffrence, but not so much these plants,they've suffered from stretching and weak lighting so i dont see them getting that much from them so i understand your not wanting to do anything till next grow, but why not start next grow now? by the time the ones u have now are done flowering they will be nice and big and ready to flower. have u considered a seperate clone/veg box yet? perpetual grows are awesome, nice pretty much so evenly spaced harvests, its really easy too. lol. heres how i'd do it in your situation. 1.get your veg area set up, keep the lights close enough so they dont stretch. early on you wont need quite as much light so till they get a lil bigger keep the extra lighting in the flowering area, just dont let them outgrow the lighting. when you toss the *new plants* into veg however take almost all the lighting w/them into the flowering area.
2. when the plants in flower are about 2 weeks from being done go ahead and cut 3-4 clones(till u master cloning, then 2 is alright, the extras are in case you kill some of them. lol.) from your female veg plants. just let them chill and root w/their mothers for now.
3. when your flower are done go and switch your mothers to flowering and position the by then rooted and totally ready to grow clones where they get as much light as possible.
4. repeat the cycle.
After a few harvest youll be able to upgrade the flowering area to a 400w hps or so and then when you get that far you can devote all the cfls to your veg box.
