400w HID question

Hey everyone,

Just wondering if I would need a cooltube for a 400w HID set up in a room with the following dimensions 9x7x9?
Also there is a small AC unit built in and ceiling fan that works great for keeping comfortable temps in the hot summer days of Brazil.

Appreciate anyone that can chime in.
Peace

No, the ac and fan should suffice, imo

you don't need cooltube, it's just up to you if you want it, but you'll have to vent the room regardless

Thanks for the reply guys. I didn't think I'd need one either as I feel the room has plenty of space for heat to be dispersed. Will run ac and ceiling fan for sure.
