Has anyone ever tried using C02 to help enhance plant growth? I was thinking of trying one of these to hang in my greenhouse and see if it helps the plants health. It's not that my plants are unhealthy but I have heard that added C02 enhances the health and growth of plants.

While I understand CO2 generators, I don't see how this would help in a greenhouse. CO2 is heavier than air and would sink to the floor. Think about the way dry ice vapor (CO2) flows over the sides of a container. In a terrarium or enclosed space It might make sense. I used a CO2 generator for a planted aquarium that I had. In that case, the gas was dissolved in the water and stayed around longer.

So my greenhouse is only 2'x3'x7'. I was thinking of hanging it above the plants as they say to do.

That makes sense.
