Its very difficult for me to keep the res temp below 20C as Im growing in a cab. Min 22C/Max 24C so I have no choice but to use an additive to kill pathogens.If you keep your nutrient solution below 68ºf
you will never need to use H2o2.
The max amount you should ever use in dwc is 2ml/gl
of 35% H2o2.
Avoid using H2o2 if at all possible.
A cool rez is the best way to avoid the need for H2o2.

I dont have money for a chiller & even if I did I have no extra space in the cab.
