It is essential to provide fresh air exchange for indoor growing environments to maintain healthy plants and achieve maximum yields. Fans allow you to clear the ‘stale’ air from your growroom and replace it with fresh air and when used with a carbon filter can clean the ‘stale’ air before leaving the room itself. Check out our massive range of odour killing products from ONA block’s through to Uvonair’s hugely effective ozone generators.

Exhale Co2 Bag – Medium-2kg

£35.00 £25.00 incl. Vat

The Birth of ExHale

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 actual becoming a hybrid worth offering to the public. This process would be years in the making.

That same philosophy went into creating ExHale. It is well known that mycelium releases CO2 just like humans. When looking into the possibility of utilizing mycelial-cultivated CO2 for plant production it was obvious to me, it has to be a special strain that only wants to produce CO2.

With most cultivated mushrooms, your goal is to get mushrooms. Go figure. After you have harvested your crop what you have left is fairly valuable, mostly for compost, which in itself produces CO2. The gig is a mycelial strain that produces little or no primordia has more vigor and therefore produces more CO2 for a longer period of time. Just like a mother plant, ExHale just keeps cranking as if there is no end to the day.

ExHale came out of a true love of agriculture and out of the need for a less expensive, easier, safer and more harmonious way to provide your plants with CO2.

How It Works

Photosynthesis is the process by which plant leaves make carbohydrates. Sunlight, CO2 and water are converted into carbohydrates and O2 by the action of chlorophyll in the chloroplasts of the plant. Plants growing indoors under artificial light often lack enough CO2 to efficiently photosynthesize. When plants are able to maximize the process of photosynthesis, the result is larger plants with larger yields.

ExHale cultivates CO2 24 hours a day with no need to refill bottles or use expensive CO2 production units. The power of ExHale lies in the mycelial mass inside the vented cultivator. This mycelial mass cultivates CO2 and the microporous breather patch releases CO2 continually for up to 6 months.

The ExHale Cultivator is designed for small to medium grow spaces , or more specifically 1 ExHale Cultivator will provide 4-6 plants with the CO2 they need. ExHale can be used for both vegetative plant growth as well as for fruit and flower production.

How to Use ExHale

ExHale comes complete and is cultivating CO2 even before you get out of the checkout line. No need to turn it on or turn it off, simply place ExHale in your grow space and leave it alone to do its job.

A continuous shower of CO2 directly onto your plants is the most efficient way to deliver CO2. Placing the ExHale Cultivator slightly above the level of your plants will insure they receive the CO2 they need 24 hours a day for up to 6 months.
