ExHale cultivates CO2 24 hours a day with no need to refill bottles or use expensive CO2 production units. The power of ExHale lies in the mycelial mass inside the vented cultivator. This mycelial mass cultivates CO2 and the one-way breather patch releases CO2 continually for up to 6 months.
The new XL ExHale CO2 is designed for up to a 6’x 6’ area.
