You would be surprised skint what you can grow under cfls, here is a photo of a round of clones I have had waiting to go into flower room, they are about 2 months old now and have been trimmed back, lst, supercropped, topped etc all in attempts to slow down growth, even running a bare minimum of nutes. CFL can do a good job, although I do flower under HPS so I cant say about flowering for CFLs.
This is 1 80w CFL only (also in an attempt to restrict light as I didn't want fast growth in veg), I am running a water flush now for a week, and then will be harvesting next week at which point I will have a massive clean job for a quick turn around and these girls into flower.
3rd hydro grow seeds are also in cubes now so will be moving them into this veg room in about 1-2 weeks.
CFL are really saving me on power, I was running an 18hour mh cycle for a few weeks but to be honest its not worth the power usage and from the looks of my current 3 plants in hydro it looks like about 5-6oz, not bad for first grow, will have to see dry weight when I harvest, have about 4-5 colas that are about sauce bottle size in height and about 1 1/2 inches across, so some massive colas from those. I am hoping for about 4oz + dry and I have an outdoor grow also that is about a month from harvest, hoping for another 5oz from that.
Good luck and wow on the amount of seeds, that is a lot to germinate. You probably should have just popped double what you expected to grow with that light coverage and ditch the weak ones. Usually its not worth wasting seeds, but I guess as many of yours are bag seed its not such a big issue.
