Mushroom based CO² bags designed to increase CO² levels naturally for indoor and small area plant growth, they are ideal for growing micro greens and more in indoor green houses and grow tents. 30-40% Yield increases can easily be achieved with supplemented CO² levels!

The bag comes ready to go, simply place the bag in the grow environment with the filter patch stood up to allow the CO2 to come out of the bag into the growing environment. Easy as that!

2-4 Mushroom CO² production bags in a 1200x1200 grow tent will supply good CO² levels, the bag will produce for about 4-6 months as the mycelium breaks down the carbon producing mix in the bag.  More bags can be added if higher CO² levels are desired or servicing larger areas with more plants.

2 Bags in the 2 tier mini green house picture took the CO² levels from ambient (400-420ppm) to 2100-2300ppm in under an hour! 

Increasing CO² levels in commercial green houses is a standard process these days, often done with complex systems burning natural gas, luckily we have nature on our side taking advantage of mushrooms breaking down carbon mix and turning it into CO² gives us a more eco friendly, less dangerous and cheaper option!

As long as no holes are made in the plastic bag no mushrooms will grow.

Contents in the bag have been sterilized so there is no risk of introducing disease or bugs into the growing environment.

Once bag is finished it will be very soft and squishy as the contents have been turned into CO² and dispersed through the filter. The remaining contents of the bag make fantastic compost for the garden!
