ExHale can be used for both vegetative plant growth as well as for fruit and flower production. 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 microporous breather patch releases CO2 continually for up to 6 months. ExHale®-Homegrown CO2 is a revolution in indoor CO2 production systems.
Maintenance Free, no heat, no electricity, just CO2.
