the only thing is that you really need to be careful of heat, you pretty much need some sort of ventalation if your growing in a closet or something with any HID lighting. the props to the cfl's is almost no heat off those suckers.

I've used a 250W MH from seedling and always got great results; just make sure you have proper ventilation with a fan oscillating the air helping disperse the heat from the HID and keep at a proper distance and you should be fine.

just checked them there and leaves are dried up put them back under a cfl.....i hope i have not killed it. I think they were 2 young and the 400w MH was 2 strong as I have them in a small space.....nitemare
