Hi everyone im just starting my second grow and it's been about a year and a half since my first. Im modifying my setup from the first time around and need some advice on co2. I bought a hydrofarm inline fan and a carbon filter for ventilation without realizing the room should be sealed to use co2. Is there any way i can get around that? I would love to still be able to use co2 and any advice would be much appreciated
