Do you think the majority of commercial hydroponic green house growers are wrong. They use chlorine at 4 ppm or higher added into the pipesfeeding the irrigation spray heads so as to m not waster chlorine in the reservoirs through dissipation. I recommend 2.5 ppm as an initail 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 containiing up to 4 ppm of chlorine. Plants can tolerate extremely high anounts of chlorine. they ac 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 chlorox 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 chloroamine or hobby grade made with chlorine.

the MSDS for hobby grade:

When your wrong your wrong. This time your very wrong. Consider your self corrected.
Yes, commercial grows, but this is a hobby user. I don't see anyone corrected, this is as much an art as a science. Try not to be so rigid. :)

The star beneath a peeps post is for giving rep, and as long as your nutes are not organic bleach is good to go

If you are worried then only use 4 drops, though the amounts we are talking even with the tap is very small
bleach disipates after about 24 hours, so what I do is every 2 or 3 days add back to the amount of gals in your res, you could even go 4 or 5 days cause the bleach wipes shit out completely and takes a fair while for any bad shit to get back in your h20. It is so easy and so cheap and totally effective.
Your tap ppm is very good also

it says flora nova is a mix of organic and chemical what you think
The chlorine will kill the bacteria needed to break down the organic molecules into N-P-K for the plant to use. So by using chlorine you are neutralizing both the chlorine and the bacteria...

Best thing to do is get the resevoir temps below 70 degrees if at all possible.

absolutely worst comes to worst it will just not break down the organic parts right?? on the bottle it says it has .01% CL already in it so im curious.
 
Hypochlorous Acid is The same thing as Bleach. Hypochlorous Acid is in Bob's Brew and Clonex Cleaning Solution. Both at the same rates.Check out any label of Bob's Brew and I'm sure you can find what your looking for

Bleach is a bit cheaper

How is the bleach working out? I'm using a flood and drain system in rockwool pots (al b fuct style) and had my roots turn brown the other day. Is bleach going to help me 6-8 drops per gallon.
