Hygrozyme is a naturally derived organic solution, specifically intended to facilitate the removal and expulsion of dead organic matter that may have built up on media or medium surfaces – without altering the normal course of decomposition. Hygrozyme is the only known natural cleaner that can be used in conjunction with other standard cleaning chemicals (i.e. hydrogen peroxide). It can be used alone, where the use of chemicals is prohibited or not welcome. Hygrozyme provides the ideal natural cleaning solution. Buy Hygrozyme at Plant Lighting Hydroponics and save!
