ExHale CO2 Bag for Small Grow Rooms

A living mycelial mass on organic matter makes CO2 inside the bag, released through a one-way breather patch. It supplies up to 1500 ppm depending on room size and ventilation, for up to 6 months. There are no bottles to refill and no regulators, generators, or monitors to run. One bag covers roughly 3 to 5 plants.

Getting the Most CO2 From a Homegrown Bag

Hang it a little above the plants, since CO2 is heavier than air and settles downward. Keep a fan moving so the gas does not pool on the floor out of reach. In a small, recirculated room it works best. Cutting the fan for short stretches lets ppm climb. The bag starts tan and turns white as the mycelium matures, which is normal.
