Replacement Steam Canister with O-ring for low conductive waterAnden Steam Humidifiers are a grow room solution that helps you achieve ideal conditions through humidity control. As water in the canister boils and turns into steam, minerals are left behind. Minerals remaining in solution increase the conductivity of the water. Minerals also deposit onto the submerged portions of the electrodes rendering those areas ineffective. As this occurs, the level of water in the canister rises to expose more uncoated
