I have two tents one for drying and vegging one for flower.
Both have a carbon filter and an exhaust.
i have both tubes connected with a Y piece before i blow out trough the isolation under the roof tiles.
I noticed when one of the two exhaust is off the other blows a certain amount of air into the tent.
Is it a problem for the carbon filter? I was just thinking now he gets airflow from the other side,could this be a problem
I was thinking about blowing one tent directly into the other but didn’t have enough tube. And wasn’t sure what way around was better veg into flower or flower into veg.??
should I solve the issue with a homemade, one way valve?
Any experiences or suggestions about my best course of action would be appreciated.
