Thanks Don, I'll have to read up on that but I read a few places that it wasn't bad for them.
This is part of a post that I read up on:
Do you think the majority of commercial hydroponic green house growers are wrong. They use chlorine at 4 ppm or higher added into the pipes feeding the irrigation spray heads so as to m not waster chlorine in the reservoirs through dissipation. I recommend 2.5 ppm as an initial treatment reduced to 0.5 ppm as a residual level of chlorine. Tap water is allowed to contain up to 4 ppm at customers faucets. Thousands of growers of mj use tap water without any removal of chlorine. 10's of thousands of people water their houseplants, flowers and lawns with water containing up to 4 ppm of chlorine. Plants can tolerate extremely high amounts of chlorine. They can not tolerate chloride. Fish can tolerate high levels of chloride but not chlorine. Salt is sodium chloride. Plants can not tolerate high levels of chloride Caphese.
Hydrogen peroxide is a much stronger oxidizer than chlorine. It is much easier to cause problems using hydrogen peroxide than to use clorox bleach.
Too many myths in forums and on the web. Have you heard of Pythoff. It is sold in two versions. Professional/commercial made with chloromine or hobby grade made with chlorine.
I gave mixing directions based upon known strengths of Clorox bleach and flairform Pythoff, the largest seller of a chlorine treatment of root rot. It is the same strength used by most commercial greenhouse growers.
H2O2 can be used to kill the bacterium causing root rot and it will oxidize the rotten roots. However, it is an extremely strong oxidizer it is much easier to screw up with H2O2. It also provides so residual oxidation/disinfection effect. It is also not readily testable in a home as is chlorine. They even sell cheap swimming pool chlorine test kits that can measure chlorine levels in the water. There is no cheap test for whatever you used enough, to little or too much H2O2.
The pythoff bacterium is a common anerobic bacteria. Any where there is a moist warm environment without oxygen you'll find the bacterium. The bacterium however is easily killed by chlorine, a relatively weak oxidizer.
I think I will try it out and stick with the bleach for now. I have not heard any bad affects on using the bleach plus it's alot cheaper than the other stuff. There is chlorine in the water we drink everyday. About 8 drops per gallon or about 4 PPM is what they recommend for whiter roots and less algae.
