These don’t work. I have a CO2 meter in my room. I have 4 of these running in a sealed room for day. CO2 meter reads 0. If I go in the room for 5 minutes my CO2 meter reads 450ppm. These don’t put out CO2 . Spend the money on a different product or system. This is just a mental trick. You think you’re growing better. In reality you haven’t added any CO2 to your grow
I noticed the difference in my grow very quickly. My yield has almost doubled. Need I say more?
