If you guys are saying that the plants need lots of O2 then your wrong(they need Co2), but if your not sayin that then your right.
checkmark9 Reviewed by checkmark9 on . Fans On or Off during Lights Out?? I have not been running my fans during "lights out" and I am growing in a closet where the only airflow is provided by fans. The only air that comes in is through the duct work during that time. Is this ok? I'm not like suffocating my plants for 6 hours or anything right?? I'm trying to figure out what happened to my seedlings and just trying cover all the bases. Rating: 5
