is there a product you can buy where it takes in the air from your grow room and traps it, freshes it up and then releases it. I dont have an opening to my window so ventalation is slight problem. thanks
Hey HeavyBUD. It is important to provide fresh air to your grow. For the CO2 and for heat venting. Carbon filters can cycle air in the room. if the room is Enclosed I have read people use CO2.
Theyres something that takes all the stale air and blows it out of your grow room. Exaust fans, theres differnt CFMs so check how much lighting you got and/or a carbon filter could work but for the exhaust i would suggest 265 Cfm per 400w
