No Activation Needed – Place The Bags & Wait For The CO2 To Begin!

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. ExHale 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.

Plants growing under artificial light indoors often lack enough carbon dioxide to efficiently photosynthesize. Maximizing the process of photosynthesis is imperative for indoor growers and results in larger plants with greater yields. Use in vegetative and flowering stages for increased canopy size, faster growth and prolonged production during budding. Increasing CO2 levels can also help plants tolerate higher temperatures in grow rooms using bright lighting.

ExHale CO2 Bags produce carbon dioxide 24 hours a day with no need to refill bottles or install carbon dioxide production units that tend to be expensive and maintenance heavy. Bags come ready to use and should be placed as soon as possible after delivery. Please call us at 1-800-827-2847 with any questions you have about bag placement, CO2 usage or usage rates.
