ExHale Homegrown CO2
The ExHale Homegrown CO2 cultivator works 24 hours a day with no need to refill bottles or invest in a complex CO2 system. The vented cultivator unit contains a non-fruiting mycelial mass that produces CO2 continually for up to six months. Because it uses no electricity and generates no heat it doesn't need to be turned on or off; it simply sits and does its job. The ExHale cultivator is designed for small to medium grow spaces providing enough CO2 for four to six plants.
