ExHale CO2 Bags

ExHale Homegrown CO2 Bags  are revolutionary carbon dioxide production systems designed to be maintenance-free. Simply place the  ExHale CO2 Bags  slightly above the plants in your grow room to allow carbon dioxide to precipitate down onto the cultivated plants.  Ex Hale Bags  utilize natural processes of beneficial fungal mycelia to cultivate carbon dioxide for up to 6 months! Increase CO2 levels to stimulate photosynthesis and increase vegetative growth and crop yields.
