The ExHale CO2 bag with new easy-hanger is great for production of CO2 into the growing area or grow room. There is much talk about this new product, some reviews negative, many positive. We have reviewed and tested this product to find that the bags do indeed produce a high level of CO2 locally to the bag, but users must be realistic about CO2 PPM levels that can be reached when using this product in an enclosed space with ventilation equipment running full time in close proximity to the bag.
Our conclusion is that generally these bags will increase growth and yield potential of your plants, and as an inexpensive alternative to CO2 dosers. We recommend 1 bag per square metre, and replacing the bags every 3months for maximum potential of The CO2 bag.
WHY USE CO2:
The perks of increased CO2 levels within a greenhouse are universally known, and include earlier flowering, greater yields, enhanced stem strength, and weightier flowers. Plants use a process called photosynthesis, which converts water, sunlight and CO2 in to essential materials to aid their growth and overall nutrition.
With more CO2 in the air, plants become more active and efficient at absorbing it and using it. Faster conversion of CO2 in to essential nutrients, results in faster and more vigorous plant growth. Also, plants absorb CO2 through small pores on the underside of the leaves, called stomata. When the levels of CO2 are larger, the plants do not require these pores to open as often or as wide, this results in a smaller water loss and reduced probability of absorbing critically damaging air pollutants.
HOW DOES The ExHale CO2 Bag WORK:
The ExHale CO2 Bag™ contains a mycelial mass (fungus) and enough organic substrate to sustain it for at least 4 months. The mycelial mass works in the opposite way to a normal plant, it breathes in oxygen and breathes out carbon dioxide, 24 hours a day through the breather path on the bag. This creates a natural, self-sustaining, cost effective, odour free CO2 generator. The ExHale CO2 Bag™ produces no heat, and gives off CO2 as soon as you purchase it. You simply hang it up, leave it alone, and it will do the work!
HOW TO USE The ExHale CO2 Bag™:
DO NOT REMOVE THE BREATHER PATCH ON THE BAG OR PUNCTURE THE BAG IN ANY WAY.
Once you have purchased The ExHale CO2 Bag™, hang it in your growing area, just above plant height. We recommend one CO2 bag per 4ft x 4ft area. Because CO2 is heavier than oxygen, it will fall down on to the plants, giving them all the CO2 they need.
Once it is hung at the required height, you do not need to make any adjustments or refill the bag. After around 4 months the CO2 production will slowly decrease, and you will need to replace your CO2 bag.
