How bad is chloramine for my plants? If I am not growing organic and dont have to worry about killing anything in the soil, will chloramine kill my plants?
Nope.
Actually It's helpful, for plants grown in hydro, or coco, (solid state, hydro, bro'), .
(It can kill tropical fish though.)
Letting the water stand is worse than a waste of time unless it is treated with Chlorine gas.
Chlorine will "outgas", Chloramine will not.
Nowadays though, gaseous disinfection is very rare.
They switched to Chloramine for several reasons.
So. letting water sit for ? hours is counterproductive.
The Chloramine stays, the air leaves!
Flat, stagnant, water is not good for flora or fauna!
I recently did a side by side test.
Tried to get cuttings to root in rainwater vs. tap water.
The tap water, w/Chloramine was the clear winner.
It protected the cuttings from several fungal pathogens.
Just like it protects us from bacterial pathogens.
And there's nothing wrong with H2SO4 to lower PH.
Sulphur is a useful trace element.
I have used lemon juice, Phosphoric acid, and vinegar at various times.
If worried about skewing your nute mix, I'd advise Nitric acid only for vegging, and Phosphoric acid for flowering.
Sulphuric and Acetic acid, (vinegar), are suitable for both.
And taste, is subjective.
I have had superior scent, and taste from pure hydro. I have also tasted nasty crap that was organically grown.
Taste is affected by strain, harvest time, and growing
skills.
Unless it is totally hosed, the nutrient type, and the PH agent used are undetectable in the end product.
(Not talkin' foilar feed, or Neem, or Suphur burn, or Serenade, or anything that gets spritzed on the surface of the plant.
Just talkin' 'bout what enters the roots.
Ya'll can jump on me for that statement if ya wish.
But bring some kind of proof if ya don't want to get dismissed.
The "purists" that I have given unmarked samples of both kinds,
(pure hydro, and fanatically, organically, grown buds), were unable to tell them apart.
They did no better than a random guess, when pressed to test.
So, let the flaming begin.
