Should I transplant?

I'm soon going to have a 4ftx4ftx6.5ft (LxWxH) space for my two girls. I'm thinking of transplanting them, each into a 20 or 36gal tub.

Will they get out of control for the space they're going to have?

I also plan on getting somewhere between 12 and 24 23w CFLs for the space.

What are they? Established moms? That's a big tub for 2 flowering females, not that it really matters, probably help cut back a load on daily watering.

Anyways, I don't think they will get too big, especially under 23w CFL's, I would definitely consider grow cfl's if you want to use them, the big 125-250w cfl's actually work pretty darn good and you can usually get a combo from HydroFarm with both a mogul socket, reflector, and a 125w 6500k or 2700k for around 60 or 70 bucks, anymore and you are getting ripped unless it's coming with a 250watt bulb. I would still recommend MH or HPS still.

Cool, thanks for the advice bout transplanting and the tip on lighting. i've already bought all my lights for this grow so i think i'll look into those next time. also i ended up transplanting them into 5gal buckets and they appear to be loving the new space.
