I had avoided C02 addition because I saw how much of a hassle it was for my grower friend, in fact it was dangerous. Also as you have noted, the regular units add heat to the grow room which is the last thing I need. My 1000W bulbs are hot enough, thank you. But the Cool Flame® is a whole different animal, which allows me to see greener, better-yielding crops without the heat.

This is so much better than dry ice, tanks, and other generators. I like the guarantee and yes this is a very safe and comfortable unit that's built like a tank, but it's also light and portable, so it's a big win for growers like me.

C02 is necessary if you want to get 4-7 harvests per year but it's hard to do it without the heat or without having to go rent tanks all the time. I feel that the CoolFlame® solves the problems of the other generators and allows me to get almost twice as much yield per year as I would without C02.
