Exhale Homegrown CO2 Bag

Exhale Homegrown CO₂ bags offer a simple and effective way of introducing CO₂ into your grow room. Containing a fungus which reacts with light to produce carbon dioxide, these bags will work when your lights are on – meaning that your plants receive additional CO₂ only when they need it.

Each Regular Exhale bag will produce enough CO₂ for a 1m x 1m (4’ x 4’) area for up to six months. Each Extra Large Exhale bag will produce enough CO₂ for a 1.8m x 1.8m.
