Water question

So I know I have to leave my water sitting out for 24 hours to get rid of the chlorine. But what if I leave it sitting longer than that say two three days maybe even 4 days. Is that bad? Will the water go bad if I leave it sitting for a few days? I keep the jugs of water underneath my sink inside the cabinet.

Why not put an air stone in it? Loads it with oxygen, expels the chlorine quicker and it can bubble away forever...

Suggested Chloride (Cl) ppm's for cannabis in hydroponics is 110ppms.

Depending on the nutrients you're using, you need not rid them all.

You also might want to check with your water supplier whether they put chlorine or chloramine into the water.
Chloramine does not evaporate...
