Ventilation problems, indoor gardening?
I am trying to grow a small vegetable garden indoors where i am. It is very cold here I have no room in the house but the small shed was ideal sized. i insulated it well, it stays warm with a small space heater.
I cant be spending a lot a month to keep it warm. so its sealed very good.
But i have a problem. the plants dont get enough of the Co2's they need because it is sealed so well
If i run a vent into the shed it will be very cold air.
HOW can i keep the small room warm and get the co2 the plants need.?
