As I put my ferments in the grow tent I asked my chemist degree owning dad about carbon dioxide production from fermentation. To work this out is surprisingly simple. Pretty much half the sugar you ferment via yeast turns to CO2 and the other half turns to alcohol. So put 30g of sugar in and get 15g CO2 produced.

How does that relate to ppm not sure at the moment but it's a start....perhaps someone else can help with that part.

Maybe a more measured approach is required in the grow tent, but I would probably just put the ferments in there and see what happens.

Yeah that's the way I view it if there is space in there it goes in, it's going to provide some benefit. Be nice to quantify it though to see if it's worth connecting an IBC or two sat outside to the grow space

ppm is a measure of concentration, so to get that number we need the mass of air (we can figure this out from the volume more or less) inside the grow tent. Then it's grams CO2 per million grams of air.

Thought it was going to be fairly simple, thank you.

No lol you cannot supplement co2 with fungus growth lol its way too small to make a difference. Your house heater does enough

I had read that too that why I am trying to work it out. I used to work at a place that fermented 100s of IBCs of cider a year so I am curious as to what kind of scale it takes to change things.

Use a ppm meter theb
