do you de-chlorinate Tap water?

who does this? and why?
just wondering if anyone has any pics, side by sides, case studies, experiences or evidence that demonstrates tap water is harmful to plants

it is an oxidizer which will attack organic matter.

edit: in most cases it probably isn't that much of a factor, but every bit counts in a grow.

i have pics that says my tap water is not harmful to plants.

Water is not a static commodity. Check your local water supplier, or a Watersafe test kit.

de chlorination is only necesary if your trying to grow organic...the chlorine will kill benies that are essential to your grow. if your using salt based nutes its not a issue.

I believe tap water is okay in most situations but you need to know what is in "your tap water" to compensate accordingly, if required.

Potential is the source of all disagreements on cultivation. Well, potential of the plant, ego and experience all intertwined.

I think that my tap water makes my weed smell like cat-piss, when i'm using bottled water smell is gone...

I just fill a few Gallon Jugs and leave open for a few day. Just something I practice. Lived in a few places around the USA. Where the water smelled and tasted like Pool water. Better safe than Sorry.

i do it out of habit i think more than anything but never done a side by side or anything just becomes routine to fill a bucket up in the mornings and set it back in the room drop an air stone in it until the next morning.

damn, all reasonable replies
....I guess I'm getting overly cynical...

...yeah, but really my thoughts were I keep seeing all the hub bub over removing chlorine and couldn't figure out whats the deal...but yeah, organic is organic, so I can see where that makes sense (I'm not a big organic believer, but I ain't arguing with it either)

...sometime I wonder if we (myself included) sometimes just copy what works for others w/o questioning it... I think some methodologies in hobbies are kinda junk science and we just repeat the status quo ... doesn't hurt to revisit a few thing we do I think...

There was a study done once about chlorinated water and its impact on beneficials.

The study showed that yes initially beneficials were affected but after 24hours they had restocked their numbers to that before the chlorine water.

Also chlorine is used by plants.

Another thing, depending upon how your water company treats their water you could be leaving tap water out for years trying to remove chloramines as they don't evaporate.


Personally I fill my water container with tap water, add my nutes, wait 1hour and correct my pH. Then I feed the plants.


However I'm not an organic guy.
