@Schnabeldino, I really respect your curiosity and willingness to test things yourself – that’s the best way to grow as a grower! 🙌
From what I’ve seen and experienced, CO2 works best in environments that already push the limits: very high PPFD, perfect VPD, and dialed-in nutrients.
In a smaller tent, adding CO2 without optimizing everything else might just add complexity – and sometimes even create problems like stretching or heat buildup. And in a small room it is very difficult to maintain the right level of CO2 because there is a lot of air circulation due to, for example, the smell.
So maybe it's not that CO2 doesn't work… it just only shows its value when the rest is maxed out. I have never tried it because in my opinion it just doesn't make sense. If you go for it, I’m curious about your results! 😎
