ExHale CO2 Bag cultivates CO2 all day with no need to refill bottles or use expensive CO2 production units. The entire power of ExHale lies in the patent-pending mass inside the vented cultivator. This mycelial mass cultivates the CO2 and the microporous breather patch releases all the CO2 continuously for up to six months!
Hang the bag above your plants as a continuous shower of CO2 directly onto your plants is the most efficient way to deliver CO2. Each bag includes a hanger!
Best suited for 4′ x 4′ grow space or 128 cubic foot space!
