Exhale CO2 Cultivating Bag for Indoor Grow Rooms

ExHale Homegrown CO2 Bags provide a continuous supply of carbon dioxide with no need to refill bottles or use expensive regulators, generators and monitors. The power of the product lies in the mycelial mass, which is growing on organic matter inside the cultivator, and the one-way breather patch located on the bag. Supplies up to 1500 ppm CO2, depending upon room size and ventilation for up to 6 months. Easy to use, just hang slightly above the height of the plants in your grow space. Each bag will provide 4-6 plants with a continuous shower of CO2. No need to turn it on or off -- simply leave it alone to do its job!

Simply hang the bag above your plants (CO2 is heavier than air, so it will fall) and keep the air moving in your grow space with a fan. The moving air will keep the CO2 from staying near the floor where your plants can't reach it. This item works best for your indoor/hydroponic garden when the room is small and/or recirculates the air within it. Also, periodically turning your fan off will help the CO2 ppm increase in your room to give your plants a boost. And remember, plants can be comfortable in higher temperatures when the CO2 ppm is relatively high.

Use one bag per every 3-5 plants in your grow room.

*Exhale bag contents start off a little brown or tan in color, they quickly turn white as the mycelial mass inside grows and matures- there is nothing wrong with your bag if it a variety of browns and whites.

Another awesome product!!! Review by DC
Been using these for about a year or so, and gotta say I really like them! They hang there appearing to do nothing; however, the growth rate increase is amazing! Well worth the small investment! (Posted on 4/8/13)

I couldn't believe the difference at how "happy" my plants got after having these bags in the room in place of the more costly CO2 tanks. The stems got thicker & they just grew like crazy! I'm so glad I bought these, I totally recommend them!! :) (Posted on 8/22/12)
