How does the ExHale CO2 Bag work?
It's a self-activated, passive CO2 source that you hang in the grow space -- no tank, regulator, or controller required.
What's the difference between the ExHale Original, 365, and XL?
They're sized differently for different room volumes and how long you want the bag to remain active before replacement.
