for my most recent grow i started using yeast and sugar mixed with water in a 5 gallong bucket for a co2 boost...its workin great besides the fact that it runs out in about 2 days n im pretty sure most of it is getting wasted and i dont have an air lock or some kind of vaulve system...besides that the plants are growing much more rapidly but i was wondering of how to make my methods more effcetive...any suggestions?
Space must be completely sealed, exhaust fans need to have off time for Co2 to be effective, it will pull Co2 straight out. Co2 is heavier than o2 and will fall to the bottom of the space. Temps should be around 80f. I would place it above your plants or behind an oscillating fan blowing over the canopy.
