So guys I hit good numbers without c02 but wanted try giving it a go. Now I use propane tank with burner. I’ve tried let air out room when lights off and bring air in every 30 min to try exchange air Incase any bad gases. Reason being plants show problems soon I introduce co2. I’m in canna coco , auto feed 55g drum I usually put 150-250 ml cal mag and 550 ml A&b 5.8-6.2 dep on strain. I’m post sum pics of leaves
