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.

69NovAss Reviewed by 69NovAss on . 1000w MH or 400w HPS My grow box is 3' x 4' and I have both a 400w hps and a 1000w MH. I need to know which one would be best to use or should I use the 1000w just for the veg and the 400HPS to bud. or can I just use the 1000w from start to finish? If I get more air flow I may try to use both but that seems like a lot for a box this size. that would put me to almost 120 watts per square foot. :eek: THANKS :D sorry I think I may have posted this in the wrong spot. :( Rating: 5
