@dkim68 Plants use CO2 for photosynthesis just as we use oxygen for respiration. In fact plants rarely get proper levels of CO2 so I don’t know why people would be eliminating it from a growing space.

@dkim68 carbon scrubbers clean the smell not the co2. 🙁

grow nerds!

I’m a n00b about this CO2 stuff. I see some videos where people are running CO2 scrubbers to remove it from their grow rooms. This one is promoting the generation of CO2. It’s left me confused as to what I should do. If the purpose is to increase humidity, why don’t people just run humidiers or vaporizers in their grow rooms? If CO2 is good, why do some people try to remove it from their grow rooms. I don’t get it.

Mix 2 cups warm water, 2 cups sugar, 1 tsp baking soda, 2 cups cold water- mix well. Then add 2 tsp yeast ( the kind in the bread aisle in a little jar) and leave it alone, put in an empty milk jug and change once a week.

what r the co2 candles like i heard there preyy good need more advice

Thanks for that.Peace
