Is it practical to attempt CO2 supplementation in a grow tent?

@airedog If you like mushrooms You can grow a mushroom variety that likes warm weather, Pink oyster is the First one that comes to mind. inside of a grow tent w/plants. mushrooms take in oxygen and exhale carbon dioxide. That’s what those exhale bags are.
Plenty of cheap Hassle free mushroom grown kits online basically “set and forget”. Plus you can eat the mushrooms.:mushroom:
