Added by: MisterIto Last edited by: MisterIto Viewed: 972 times Rated by 16 users: 7.50/10 There are several economical delivery methods available to indoor growers. Carbon dioxide generators burn natural gas or compressed propane to produce carbon dioxide and water vapor. Carbon dioxide is also available at welding supply stores in compressed 5, 20, 35 and 50 pound tanks for refill. A tank regulator, infrared sensor and/or sequntial timer are necessary to release the carbon dioxide at proper intervals to maintain consistent levels. Recommended carbon dioxide supplementation is between 1000 and 2000ppm, depending on light intensity, from germination or during the rooting of cuttings through final maturation. The leaves will develop larger stomata when undergoing development within a carbon dioxide supplemented atmosphere, increasing their ability to photosynthesize when fully developed. Suplementation delays maturation by keeping the plant's metabolism producing additional growth, instead of ripening. Use it
