The ExHale COworks 24/7 for 6 months guaranteed.

ExHale is beneficial for vegetative as well as for fruit and flower production. Use one bag for the complete cycle of growing your plants.

When plants are grown indoors they can’t get enough CO2 to efficiently photosynthesize. When plants are able to maximize the process of photosynthesis, the results are larger plants and larger yields.

100% natural, ExHale CO2 bags are the safest way to get CO2 to your plants. No bottles to refill, no timers to set up, no gasses escaping into the atmosphere.

Uses a special Mycelium culture that has been developed for its slow release over time, the vented bag will produce CO2 for at least 6 months, raising the CO2 levels inside your tent by 500 ppm over existing air levels.

When you 1st get the ExHale CO2 bag it will be brown, but in a few weeks, the color of the bag changes to a whitish color. When the bag turns white the Mycelium culture is fully active and you are getting optimum CO2 levels.

ExHale CO2 bags are designed for small to medium-sized grow spaces.
