Nice I always wondered how the higher you go up the less oxygen there is, and how the plants would do. I was up at the top of Mauna Kea a few days ago to see the snow, and I wondered if in one of the telescopes someone has ever grown marijuana, with tanks of co2. How would the plants react to the lake of oxygen, since they dont use oxygen? how high is your elevation, the plants look great ,,,,chris
