Frequently asked questions
Why is CO2 important?
How big of a space can The ExHale cover?
The ExHale Cultivator is designed for small to medium grow spaces, providing 4 to 6 plants with the CO2 they need.
Do I need to turn it on?
The only bag that requires activation is The ExHale 365 bag.
After removing the hanger, move the mycelial mass onto the substrate. In roughly two weeks your bag will be producing its full CO2 capacity.
Where do I place The Exhale bag in my tent or grow room?
Because CO2 is heavier than air we recommend hanging the bag one to two feet directly above your plants. Each bag comes with a hanger but how you attach it is up to you. After hanging your bag, a continuous shower of CO2 will fall directly onto your plants. This is the most efficient way to deliver the CO2 they need 24 hours a day for up to six months.
What is the official flow rate of one of these bags?
Here is our official CO2 Flow Information:
Is this some kind of kit?
We introduced the first retail ready packaged mushroom kit many years ago. ExHale is not a kit in a bag, ExHale is a stand alone product, an all-in-one, all-natural, CO2 production unit.
Will my bag grow mushrooms? It iss a "mushroom bag" afterall
The ExHale bag is a non-fruiting mushroom bag which means its a single mass of mycelium and you will not see classic mushrooms forming.
Where did the idea for ExHale come from?
Some 20 years ago I realized the biological function of mycelium. Before that for 25 years I had lived a life of a seed breeder’s son. My father always had a saying; “First the Seed”, when I was young we would plant thousands of crosses hoping to get 20-30 that showed promise of actually becoming a hybrid worth offering to the public. This process would be years in the making.
Does CO2 help with clones and rooting?
An often overlooked and under studied aspect of plant response to CO2 is on the below ground processes. When exposed to increased CO2, roots have been observed to become more numerous, longer, thicker, and faster growing in many plant species. When cloning plants, root growth appears 3-5 days sooner with CO2 enrichment versus without. Although some things are known about root responses to CO2 enrichment, much remains to be learned. Nevertheless, it is clear that plant roots, like other parts of the plant, typically do better in CO2 enriched air versus ambient air.
What does light have to do with CO2?
Photosynthesis has two parts. The light dependent reactions and the light independent ones. The light dependent part is the use of light to "steal" electrons from water. This is the process that produces oxygen. The light independent part is carbon fixation.
Does CO2 really improve yields or just make for a healthier plant?
The answer is both. The goal of CO2 enrichment is to reduce the time from seedling to harvest and to speed up growth and increase yields. Plants grown with elevated CO2 are more able to resist insects and diseases, which makes for a healthier plant. In a study, lettuce was grown in a greenhouse with ambient air versus lettuce grown in a greenhouse with CO2 enrichment. The test showed the lettuce grown in the greenhouse with ambient air was ready to harvest in 59 days. In the greenhouse with CO2 enrichment the lettuce was harvested in 48 days.
Can you have too much CO2?
Too much CO2 can be detrimental for plants. When CO2 levels rise to high, the plants ability to perform transpiration during photosynthesis is reduced. With lower transpiration rates, fewer nutrients are drawn thru the plant, thus less food enters the plant and growth slows down. High CO2 levels can cause necrosis spots to appear on leaves. These dead tissue spots are an invitation for bacteria and mold to appear. The bacteria and mold feed on the dead tissue and can cause plant damage, lower yields and in some cases cause crop failure. It has been shown that CO2 levels around 1200- 1500 ppm provide for optimal growth. With levels above this you are only wasting CO2 and potentially asking for trouble.
