ExHale 365 Self-Activated CO2 Bag for a 4x4 ft Tent

The ExHale 365 CO2 Bag Runs for Nine Months CO2 supplementation usually means a tank, a regulator and a controller. This is none of those. Living mycelium growing on organic matter produces the gas as a by-product of its own metabolism. The bag feeds a 4x4 ft footprint, which is about 128 cubic feet of tent. Output runs for up to nine months, with the first six at peak production. There is no power draw, no heat and nothing to refill. A separation seal on the bag doubles as the hanger. Activation happens once, by breaking that seal, and then it is left alone. It is suitable for certified organic production. ExHale make it in the USA. Where a Self Activated Mycelium Bag Belongs in a Tent Placement decides whether this works or not. Carbon dioxide is heavier than air, so the bag hangs just above the canopy and lets the gas fall onto the leaves. Too high and it disperses before it reaches anything. If a fan is running, put the bag near the fresh-air intake so the gas gets distributed. Heavy exhaust works against you, because it pulls the gas straight out of the room. Sealed or lightly vented spaces get far more from it than a hard-exhausted one. Keep it out of direct water. Supplementing carbon dioxide only pays when light and nutrition are already dialled in. In a room limited by something else, this will not be the fix.
