Whats going on bender .
I would recomend the 400 watt
hps in your box. That would still give you
well over 50watts per square
foot.
So, what type of ventilation do
you have set up in your box?
thats a big factor when it comes
grow boxes, I've recently found
out with my C13 running a 250watt
hps. Good Luck and happy growing.
