The Green Pad CO2 Generators, with their innovative activated-by-humidity technology, is proud to announce that HydroFarm will add the full Green Pad product line to its suite of quality indoor grow supplies. The Green Pad CO2 Generators offer CO2 options never seen before. Options include the Original Green Pad for the hobbyist’s small garden and the innovation in propagation, the highly successful Green Pad Jr. There is also an option for larger gardens now available—The Grand Daddy Green Pad. The Green Pad CO2 Generators offer CO2 on demand for greater flexibility, giving growers control of how much CO2 is needed, and when. Without expiration issues, and with a slow or fast CO2 release, The Green Pads offer growers a back-up for existing systems or supplementation for those systems to avoid heat buildup and tank refills.
