Bleach to nutrient solution.

[floriangrower]

Hey,

soon I want to start my first DWC grow. I have read that people lr use bleach to keep their nutrient solution sterile and I find that a cool way. My only worry is that if I add the diluted bleach water mixture to the nutrient solution, the bleach might react with the fertilizer in the rez and forms a toxic gas called chlorine gas which is verx harmful to humas. Am I overreacting or are there some dangers and precautions I should look for?

regards

Depends on nutes you use.but yes you can create that.small quantity but it will remove bleach from your res

Overreacting. The effective dosage of 3-5ppm residual chlorine doesn't do anything in terms of causing bad reactions and/or precipitations.

Here's the dilution calculator:

So, as far as you guys tell me, there should be no problem to make a bleach batch with like 500ppm and add 1 liter of it my 100 liter nutrient solution to achieve 5ppm. my base chloride ppm is almost 0 btw. No worries of gas right? Is there a right order to add the nutrients/bleach? I am using GHE (T. A.) TriPart for hardwater, GHE CalMg, GHE Silicate and GHE PH-.

Sodium hypochlorite and chloride aren’t going to interact to form chlorine or especially chlorine gas.

really, i thought they do with ammonia?

Are you using bleach (sodium hypochlorite) or ammonia? 2 very different things.

I am using normal bleach with 2.8g sodium hypochlorite at 100gramm. Ammonia is in the GHE FloraGrow (Ammoniacal Nitrogen).

There’s so little ammonia in that product that any reaction probably is immeasurable. Don’t sweat it.

Yea I thought about that too, it's about 2%. I have no chemistry knowledge tho, I am an engineer so I am very careful about things I dont know. Thanks for the reply!

One time I added pool shock to a res with h2o2 in it. The reaction was this gray smoke like color rolling building in the res and I thought "oh fuck, it's about to explode" and then I ran away and googled until I was calm again.

i'd be careful running at 5ppm. that's the upper threshold for safe level

because of the plants or because of my health?

yea i'd start with 5ppm like 2 days before i plant them into the netpots and then add 3 ppm weekly to keep the bacteria away

btw is there a list of the optimal amounts of nutrients cannabis needs with R/O water in hydro?

 

[rkymtnman]

because of the plants or because of my health?

either

 

[floriangrower]

either

ok i will make sure to keep it under 5 ppm

The h2o2 and cal hypo mixed and it basically just broke down into hypochloric acid and oxygen.

I am not a chemist and this was about 2 weeks ago, so don't quote me on that.
