So the plants are in a closet with closed doors and every thing separated from the room, but still attached. the room is small and has a cage with 2 guinea pigs in it. Could this affect the plants at all? thanks you Fro$tee
It could if they have a dirty cage or some diseases. Otherwise they're making CO2 for you, so thats good.
yeah it should not be a problem. But keep the little guys safe from your nutes and chemicals and heat. No exhausting on the little guys
