co2

Want to add co2 to my grow room. Wanted to know do you use the co2 for the hole grow or just for the flowering. also do you stop using before u harvest or do you stop it a couple of wk before harvest? using homemade co2 (yeast, sugar, and warm water).

It won't do much during veg. It's recommended you use it during flowering. I dunno if you have to stop before harvest or not.

For using CO2 in your growroom, use it only during the flowering phase. Yes it helps with plant growth during the vegetative stage, but nothing substantial I have seen so far from multiple grow room operations. Also you can use it the entire time, from once you begin flowering till harvest. ^.^

making it with yeast, sugar, and water. any suggestions on how much of each product to use. I am using 2 packs of yeast to 1 liter of water and 1 1/2 oz of sugar. Am I way off with this.
