new setup advice (grow tent)

[misk]

im setting up and building a new grow tent of my own (growing 6 plants off a 600watt HPS), but i can only run a single exhaust fan.

am i better off pumping fresh air in from a vent that leads outside (with vents in the tent for air to excape), or drawing the hot air out of the tent, with ducting to the vent but no fan for fresh air to be drawn in (with no vents in the tent).

the tent will be around 2 metres tall by 1.5 long by 2 metres wide.

any other advice regarding grow tents would be awsome, cheers.

Place an exhaust fan as high as possible to catch as much hot air as possible. Leave a large opening (2 to 3 times as large as your exhaust) near the bottom to get as much cool air as needed.
