Go get a cfl for now. This can last you a while and in the meantime, do some homework on how to care for this great plant you've brought into the world
Bigger trees in the ground, but pots can be moved around. Depends on your set up.
Chongsbuddy hit it on the head too about pots getting hot in the sun and rootbound.
BUT like I said, pots can be moved.
meaning what will be the difference between the two groups during and after flowering?
Will the 5 hours of differing bulbs make any difference given the 7 hours of direct sun?
you have to be very careful here in calif because the market is stll unregulated and the rules are not fully formulated yet.
you can still get busted for supplying to clubs. you can still get busted for transporting. you can still get busted for cultivation.
and even if you are "legal", you...
Better not be relying on just the winter sun to grow your babies.
no way, this is considered an indoor grow, however, half the days since dec have been 6 hours sun!!!
