Another great update CO

I've asked this question before but it was overlooked. Why do you like to grow under negative pressure, is it to control odour or is it beneficial to your plants?

Main reason is it is not letting any hot air sit in tent. Two is all odor is going threw filter and not being pushed out tent vents. Three is it clears out co2 and not push it in rooms when timer turns e vac fans on. Forth reason is I have fans up high blowing over lights to mover hot air right to the filter and with neg pressure it does not allow hot air form the top fans to get pushed down on plants.
