A question from a fellow grower:
I have been forced to use tents because I relocated my residence and don’t have a wide open basement anymore. have circulation fans in the tent to move the air, bought LED lights to keep power and heat issue to a minimum. What I would like to know if how often do I really need to replenish the tent with fresh air?? I understand that the larger the canopy the more this will need to be done. I have a huge carbon filter for obvious reasons hooked to my high CFM exhaust fan. I know its best to keep fresh air in the grow area, but does it have to be constant or can I run it a few times an hour?
