Growing plants is a little like making a fire: light, from the sun or from grow bulbs is the spark, but CO2 is the fuel that actually burns to make healthy plant tissue, blooms and blossoms. More CO2 means your plants can take advantage of more light.

The Green Pad CO2 Generator is a dead-simple and convenient way to boost CO2 levels in your grow room, without the expense and hassle of a gas burner or a CO2 tank and regulator. Just unfold the towel-sized pad, spritz it with water to activate, and hang it in your tent or growing area. It will gently release CO2 for ten days, and one or two pads can keep an 800 sf grow room above 1000 PMM of CO2!

Pro-tip: Stagger your Green Pad CO2 Generator use by starting another pad after one week. Then, as the first pad winds down, the second will be cranking CO2 out to keep your plants healthy and growing.
