The developed ExHale strain is now kept secure in a number of strain vaults at the ExHale farm and at some off-site locations. Using his trained eye, the threads of mycelium that showed the most desirable characteristics were selectively transferred and sub-cultured in petri dishes to ensure that the desirable characteristics were preserved. After this tedious process, Babcock focused on one strain in particular that held the most promise. In order to find the strain used in ExHale products, Babcock and his team looked closely at each strain’s speed of colonization, its straight of mycelial threads, its inability to fruit, and the amount of CO 2 produced. This is because after a strain produces a fruiting body, the CO 2 production decreases. A non-fruiting strain will produce more CO 2 for a longer period of time. However, if you are looking for a strain that produces CO 2, the opposite is true. Babcock’s expertise in mushroom cultivation taught him that if your goal is to produce a lot of mushrooms, you want a strain that produces fruit easily and consistently. One of those 200 strains ended up being the CO 2 producing giant that is now used in ExHale CO 2 products. The birth of the ExHale Company happened during a trip to China in 2002 when Babcock collected more than 200 fungus strains. Founder Glen Babcock spent years researching and searching for the perfect fungus strain to use for CO 2 production. The ExHale – Homegrown CO 2ĮxHale CO 2 bags are mycelium-based products that use a special strain of fungus to produce CO 2. One of the easiest and most cost effective ways a grower can add CO 2 to his or her growing environment is to use an ExHale CO 2 bag. Plants grown in a CO 2 enriched environment are generally more robust and can produce larger fruits and flowers. Enriching the growing space with CO 2 can boost the rate of photosynthesis and, in turn, boost growth rates.



The ability to increase CO 2 levels within the growing space is one of the biggest advantages of the heightened control provided by indoor horticulture. However, indoor gardeners and greenhouse growers have the unique opportunity to raise the CO 2 level in the garden to levels above that of the ambient air. Sufficient air flow is the key to maintaining ambient CO 2 levels within an indoor garden or greenhouse.

Without an adequate amount of CO 2, the plants will never perform up to their full potential. It can be a challenge for gardeners to provide enough CO 2 for photosynthesis to an indoor garden or greenhouse that is packed wall to wall with plants. Oscillating and intake fans are used to bring fresh air (which contains CO 2) into the garden space. Just as plants grown outdoors need CO 2 for photosynthesis so do plants grown in an indoor garden or greenhouse.
