CO2 in Grow Room

[Scooter]

Growing inside. Grow room is not sealed. Open room everyday and circulate fresh air all day. Constant temp here year round.HOT. 85+ all year. My grows have been very successful but am looking to upgrade. I have been reading about CO2. With higher CO2 levels the plants are able to withstand heat better so ive read.Thinking outside of the box compost is a CO2 generator. Has anyone used compost in the grow room. Im thinking a 5 gallon bucket. All input is appreciated. What about other systems that have been used by others? Please keep in mind money is an issue here.
Thanks

I have used yeast in the past - like your starting bread - yeast, warm water and something sweet to bloom the yeast - lasts about a week.

I used bakers yeast and sugar water in a large “Texas micky” bottle when I was into fish keeping. Problem I ran into was the nasty smell that equaled warm skunky beer.

Two questions: Did it help and what exact recipe did you use?

[Canuck147]

I'm not sure if it did anything - only way to tell is have 2 tents and give one CO2 and the other not.

Water, yeast and sugar make CO2, what I read is you breathing around them is enuf. I brew wine/beer in the grow room and see no dif
I gallon water room temp, a pack yeast (pinch of any brand will do) 1/2 cup sugar, stir, do not seal,

Thanks for input. Really the only thing I am trying to combat at this point is HEAT. I get leaf taco inside but goes away outside. Just looking for ways to make the girls happier.
Thanks for reading

What is your lighting? How high above the canopy?

How about dry ice?

costly here,,, can burn your self as well

I know CO2 is good for higher light levels, but I haven’t seen anything regarding heat tolerance.
I worry you might be chasing the wrong solution to your problem. If it’s just heat, you could add an air conditioner or a DIY swamp cooler, but that will cause an increase in humidity.

What is your ambient humidity like?
