ExHale XL CO2 Bag for Medium Rooms
This larger cultivator covers up to 6x6 ft (288 cu ft) and supplies up to 1500 ppm of CO2 for up to 6 months. A living mycelial mass makes the gas and a one-way breather patch meters it out steadily. There is no generator, monitor, or refill to manage. Hang it and leave it alone.
Running an ExHale XL Bag in a Grow Room
Hang the bag above plant height so the heavier CO2 drifts down onto the canopy. A fan keeps the gas moving instead of pooling on the floor. Short fan-off stretches let ppm build in a recirculated room. Watch the bag shift from tan to white as the mycelium matures. That color change is normal and shows healthy growth.
