It's a must .
You gotta get rid of the old depleted co2 before replenishing it w/ new .

I agree... You wouldn't want to breathe old stale air all the time, would ya? Neither do your plants :)

Hell ya it works. Its actually ideal, its called a sealed grow and its been perfected. I have personally seen it done very successfully.

Not only for keeping the plants cool and getting fresh air, your going to appriciate the ventilation when things start smelling. That dank is gonna stink up the whole place!:stoned:

Check the thread by Tranoble called 'sealed room 3 lbs a light'. That explains the technique.

Yep- done it.

If you can strip water vapor, and replenish CO2, yer all good.

You will still need circulation fans.
