You don't need CO2 at this point anyway, and where is your lighting? What kind of lighting?I see no bugs...I'm 100% positive... maybe heat stress or light stress... but they are perfectly fine in the dome the leaves will open back up... I'm not at my usual location... could it be from lack of air flow around the dome... maybe no con because co2 is heavier than the air and it's up high by the sealing .... idk... I'm stumped
