I tried baking soda and vinegar in the past and it made a merry mess. :( Still, when growing with LED's you need : more heat more Co2 less water less nutes My current cabinet is much smaller- 2' X 1' X 4' 8". and has an active air intake (camouflaged by a kitty litter box) so...what's a clean, safe way to increase Co2 levels? Does it really matter for such a small grow (2 plants in a small cabinet)? Rating: 5
