need help with my set up (venting?)

hello, i am getting a grow tent that is 2'8" x 2'8" x 6'
i wanted to get a 250w mh/hps light system WITHOUT a aircooled hood, just a batwing
it is a soil grow. would i be fine with just putting an oscilating fan inside, and leaving the top 2 access points open for heat to escape?

No you will need a vented hood.

so just an aircooled hood with a duct leading out? or i need to get a fan?

You'll need a fan too.

Cool tube:



Fan:



The above would allow you to run just about any light you want. Up to 400w you could use 4" hood and fan (160CFM +).
