the hygrozyme was originally formulated for use on SURGICAL instruments and the food industry. No, it has nothing to do with the food industry or use on surgical instruments. In the days of the EPA super fund massive spending on environmental clean up college researchers proved that common enzymes and bacteria found in soil will feed on petroleum products such as fuel oil, asplhaltic oils, solvents and just about any products in a liquid form made from petroleum. Several environmental engineers set up a culturing facility to culture the bacteria and enzymes in high concentrations to use for in situ clean ups (remediation). In situ means the contaminated soil or water is not dug up/pumped up and treated, but instead the bacteria and enzymes are added to the area of contamination. They then feed the bacteria and enzymes fertilizers and the enzymes and bacteria break down the petroleum products as a carbon source for building their own bodies. IE oil removal in place. How ever once the republicans (the first Bush) won the presidency the house and senate majority seats the clean up money stopped. This meant the engineers had no sells so their bacteria then became a horticultural product. Most large commercial growers laughed at that and do not buy the products. That left a MJ growing market as their chief market. The bacteria was cultured in chicken compost as it contained naturally all the enzymes, the bacteria and food plus a carbon source Originally they added for the horticultural product a south American obtained enzyme that was heat tolerant as they claimed the other bacteria and enzymes were killed by heat from composting but the special compost was not and that meant it was an effective prevention aid against pythium. They no longer use/add that enzyme or make those claims. Now you just get the leachate from composted chicken manure. Leachate is the drainage of juices and water from the compost. IE concentrate. They specifically state they do not make any claims that it is an effective treatment for root rot but that it is a good method of hopefully preventing root rot from starting. They state the best way to deal with root rot is through cleanliness and other preventive measures such as the use of Grozny. They have stated that some or their customers have made claims of successful treatment of root rot with hygrozyme. Yeah right. Fatman's word for it, but time and time again i have used h'zyme and never failed me. if you have full blown root rot, used properly you will defeat root rot in 5 days. I very, very much doubt that.as for stimulators the only thing i ever used was root66 and my roots exploded, in conjunction with hygrozyme your root system can recover from nuclear holocaust/ along the lines of what Fatman said, hygrozyme is an enzyme product, i am no scientist but dont we in our bodies use enzymes in our intestines to break down waste? i totally agree with FM again on depending what kinds of nutrients you use should dicatate what kind of protection, if using chemmy salty nutes run peroxide, if useing nutrients with microbials in them like guanos and kelps h202 isnt friendly with these, use enzymes or innoculate with beneficials
