Co2 generator with active dry yeast, sugar and warm water

That would actually interest me too 🤔 Theoretically, I think it's possible, but practically, I honestly have doubts about the effect 😅 It's just a question of whether this method can consistently produce enough CO² to actually have an impact on the plants 🤔 Especially since there is usually a continuous air exchange in most grow boxes 😅 Particularly during flowering. Well, I even doubt the expensive CO² bags from grow shops. Even with a professional setup, it's associated with very large challenges to effectively supply the plants with CO². So I don't want to dismiss the idea; I'm definitely interested in the project 😁👌 These are just some thoughts on the topic. Since making such a bag isn't associated with significant financial or time investment, it might be worth a try 🤔🤩
