There's only one way to find out. Give it a try on a plant or 2 keep track of your results somewhat and you should be good. If this water is standing in pools it may have stuff you don't want in your garden though. I personally would stay away from using water from outdoors unless you are doing an outdoor grow. Bringing things from the outside into your growroon is not usually a good idea IMO.

Thank you. I've been wanting to do a decent "Water" thread for a while. I just finally got off my ass and did it.

Thank you. Most people don't give their water a second thought yet plants are made up of mostly water as are we. I know that my horrible tapwater gave me fits until I figured out that it was around 600ppm! I see a lot of people that focus so much on their nutes, pH, soil,lights, etc. and they don't even think that their water could be the problem. Fortunately most people's tapwater will work just fine for growing. Some less fortunate ones, like myself, have to seek out other sources of water for our plants. I can't even give my tapwater to my dog!

Thanks for the info thats what ive thought all along alot of people say tap water is good enough but most is crap. i use an RO system with a carbon pre-filter its for aquariums and produces water at about 14 to 20 PPM and the girls love it i grow hydro DWC and it makes all the difference in the world solves a lot of problems i was having in the old day with tap water. It is nice to see someone put it out there with the science to back it up you number one doc.

Thanks. I seldom saw any threads about water on here and figured since I had firsthand experience with crappy tapwater that I would do a thread to help answer peoples questions about water and the different purification methods commonly used by growers. It always surprises me to see how many people have no idea what hard water is.

What about rain water..? also if you rain a air pump in the container.. would this be better..?

Rain water is usually ok to use but it depends on where you live. In some areas with a lot of industry and factories you can have acid rain which has dissolved sulfates, heavy metals and other junk. Normally though, the pH of rainwater is ideal and it has a bit of dissolved Nitrogen in it. That being said, I don't bring anything from outside into the growroon. Rainwater or anything brought in from the outside can have bugs, spores and many other things you may not want in your growroom. I would personally stick with something that I know is clean but if you are short on money or whatever then just be careful. You can boil your rainwater which would kill anything that might be in it. Also, make sure you check your pH and watch out for problems. Best of luck to you my friend.

Edit: An airstone is a good idea but it only helps chlorine dissipate a little quicker and oxygenates your water. It won't change your water quality though.
