Hi Steve –

Exhale CO2 bags come pre-activated and are already producing CO2 when you receive them. They produce CO2 24 hours a day for up to 6 months. It is designed for small to medium grow spaces , or more specifically 1 ExHale Cultivator will provide 4-6 plants with the CO2 they need. ExHale can be used for both vegetative plant growth as well as for fruit and flower production.

Hope it helps!
