That baking soda recipe is what I use on outdoor tomatos. It works.

20 pounds of co2 is 15 bucks, not even worth my time to mess with the backing soda thing.

Line your closet with white plastic film using clear packaging tape. get it as sealed as possible. Fill it up with co2 won’t take much at all to get 1100 ppm. Won’t cost much at all In co2 and get way better growth stick one plant that’s it for that size closet.

I assume you run a commercial operation. If so you must have a lot bigger than 30 pint dehumidifier. How many watts of light do you use and what size dehumidifier? How much has your yield increased using CO2?

You’ll need the 20 lb tank. Regulator and don’t forget most importantly is a co2 sensor so you can figure out how much gas is in the room. Don’t wanna overdose or underdose. And co2 is heavy it will sink to the ground so aim a fan at the ground to swish it around. Bam now you have a faster more entertaining grow to play with

That won't work where I live. I'm already limited to only growing from Sep to May due to heat. If i turn off the exhaust and seal the room it would be too hot even in winter.

i vent my tent/closet back into my room and my levels stay above 1200ppm.. my intakes just cycle it back and it also keeps my humidity in check too.

What size tent do you have? What was your yield without CO2 verse yield with CO2? How do you keep the room cool without losing CO2?

CO will increase yield by 20 percent if you have the environment in order. They will eat more food as well.

If by right enviorment you mean a green house or other less restrictive spaces that might be right. But a small tent can only hold so much. It doesn't sound like it very practical.

I dont have a comparison with vs without, but the difference is significant for sure. My space for flower is 6 long by 8 high by 2.5 wide. My veg is a 3x3x3 tent. I run a line from my co2 tank and to each setup. I cool the tents with 6 inch inline intake fans. I have exhausts on both and as long as I replenish co2 once a day my levels never go under 1200ppm

But how do you keep the room cool without AC.

You need ac

I have central ac in the house. It is winter here still though I can crack a window to bring in fresh cool air.

But if it only turns on when it needs to doesn’t cost that much

What happens to CO2 levels when you crack the window? It sounds like the whole house must be 1200 ppm in the summer.

I mean the temperature and humidity. CO in a small space works well. As mentioned above the stuff is heavy and will fall to the ground if you are not moving a lot of air around.

Yes this is correct if he is running CO2 in the whole room. I have left the door opening for a couple hours before and the lost almost a whole tank. Some of this information is not adding up IMO.

Okay I am a bit confused but thank you all I hope I reach the level of using Co2 and stuff I grow in 80*80 tent and here's a photo of my baby. Love from Africa
