Available now at the Green Pad Store


When it comes to supplementing your garden w/ CO2, The GREENPAD may be one of the most inexpensive and innovative ways to get the good gas to your plants. CO2 equipment can get expensive and The Green Pads were designed to produce enough CO2 to be of significant benefit to the indoor home garden without the up front expense of equipment but with similar results.

The Green Pad , is a sheet/pad type material that hangs inside your tent or closet and absorbs the rooms humidity(35-50%+) to power its reaction, releasing carbon dioxide. If you add periodic water misting, it will accelerate that activation.

Each full sized Green Pad lasts about 2 weeks, they peak at the end of the first week, and new Green Pad's get rotated in weekly.

To maintain higher PPM's you would want to use 1-2 Green Pads per 250-400 cubic feet of space. Of course adding more The Green Pads will certainly increase your PPM's too. You may add or subtract as many GP's as you need for your specific area.

FOR ALL YOU CURRENT GROWER USING CO2 TANKS: Don't Get Yourself in a Situation Where You've Run Out of CO2!The GreenPad is your back up for those using CO2 tanks that run empty. Keep an extra pack on hand for emergencies or when you can't get out to get a tank refill.

You can open The Green Pads and use them when they need them, in the original package. They will last at least a year. Don't get caught w/ a garden where you've depleted CO2 that your plants have become accustomed to. Drop a few Green Pads in the meantime!
