i am new to indoor growing and have jumped in with both feet. i have a question regarding vent my basement room due to co2. i have two 4x8 and a 4x4 tent, all in the same room. i am using news control units, spider farm 1000w lights. each tent is vented into the same room using carbon filters. each tent will also have its own 20lb co2 tank w/regulators. my question is, should i vent the excess co2 in the room outdoors?
