Many dudes say you got to have plenty oxygen (DO). They say in order to get more oxygen, pump more air, add 2-3 more air bubblers, taller waterfalls, buy a water chiller and chill the res water, use H2O2, and always keep hoping there will be plenty oxygen. Many say if your DO is low your roots will get sick, die and decay and you catch the a dose of the root rot like the root rot is some sort of disease. Most growers claim they never have the rot, but I see there are many post about how to cure the root rot with teas, brews, chemicals and most often just total failures and try again. It’s clearly far more popular to catch the root rot and then treat the root rot disease than prevent the rot. Preventing the rot is a problem for many dudes and always lurking in the mind every day. Keep checking those root, always watching and smelling for the rot. A few forum experts claim that low DO in res rater actually suffocates roots and that root suffocation the primary origin of the root rot disease. It’s seems logical that if you can insure and maintain optimum DO (Dissolved Oxygen Saturation) for DWC, RDWC and Benny’s then the roots will not suffocate. How de-do-dat? Do any of you dudes have any idea exactly what is the optimum DO Sat (Dissolved Oxygen Saturation) for DWC, RDWC and Benny’s require to prevent root mass suffocation?
