I have just got some today I will start it tomorrow so I will let you no I have heard it is like giving your plant steroids
i get 22-25% more bud using co2. 1lb turns into 1 1/4 lb. 1/4lb=1000 bucks co2 cost <20 bucks = 3 harvests= 3000 bucks for a 20 dollar investment
a 25%increase sounds good to me and dan if ya dont mind I would love to hear and see pics of how your grow looks after adding in your c02
I used this to test the co2 levels HTG Supply - CO2 Tester Kit I then figured out how often i needed to add co2 before it needed more. it ended up being a small 1-2 second burst right before the lights come on and again before i go to sleep. You wont ever see pics from me cause its highly illegal to grow marijuana. In fact ive never grown anything before either. It is "a friend" who does it and I just tell you his results . And Dan isnt my name, but a good guess tho
