The ExHale 365 is designed to allow CO2 to be available where you need it and when you want it. With the same award winning genetics, you can be guaranteed your garden will have the CO2 it needs. This multi patent-pending design utilizes a separation seam that allows the spawn pod to remain active and also allows for specific timing for CO2 production. With a guaranteed 3 months of distribution and shelf life, the ExHale 365 will be ready when you are. Once CO2 initiation has occurred, CO2 production will begin in earnest with peak CO2 production beginning after 30-45 days. CO2 will continue to be released for the remainder of 9 months. With 3 months of shelf life and 9 months of CO2, you’ve got yourself a year.
