at what point can i administer co2? i found an inexpensive way of making homemade co2 with sugar and yeast, just like somone had posted on this site, says its good for 2 weeks, as apposed to the baking soda vinegar method which last a few days, i am most likely going to upgrade to a good setup, but at what point does the plant use it? veg/flower?
