400watt cfl on 3 auto plants?

Does this sound good to you guys?

Are you talking 400watt or 400watt "equivalent"? The first is good, the second is, what, 70-80 real watts, not enough.

What's the benefit of running 400 real watts of CFLs vs a 250w HID? At that point the lumen output is probably pretty close right? I wanna assume that at 400w the CFLs start putting out some serious heat. 400w is definitely enough though.

Lumens will be clos but u will get harder nugs from the 250 hps

I am growing 3 (seedling at 3 weeks old) and 1 just under 2 months auto flowering plants, under 400watt. I think this is fine for the autos mainly cause they stay short. You need to keep the lights on a minimum of 18 hours a day or as much as 24. Its recommended 20. My first grow tent was kinda of small and came with all the equipment Jardin90. But got some free auto's from Attitude and gave it a try in my extra tent. I also have a Jardin120 where I am growing normal female seeds. I planted them and the auto's aprox the same time. Harvested the some other auto's that planted at the same time. And half way though another crop growing (autos) Have put my plants back in the grow tent so the bottom have can grow some more.

My point being auto's are good, for a fast turnaround.

400 watts of cfls will run much much hotter than i think you are anticipating. Take it from me, i just recently switched to HID

it depends on the temperature outisde of his grow space to I would think. or what kind of intake and exhaust system he has running.
