rainwater would be better..its clean and free
tap water has chemicals in it

I'd imagine rain water would probably be better suited due to the lower pH and lack of chlorine and such that they put into tap. I'm interested to know what others have to say on the matter though. Subscribed.

Cool, thanks..
Im doing my first transplant out of 16oz party cups into 3gal pots.

tap water doesnt really hurt the plant as long as you let it sit for a while. if your getting low on the r-water then just fill a small container up with tap water and let it sit for about 48 hours, make sure its inside. this will allow most of the chloring evap out making it more healthy that reg tap water for the plant. this is what i do, its kinda like distilling water.

yeah thats not like distilling water at all.
but good tip on leaving it out for the chlorine to evaporate.
ive used tap water on my soil grow and almost immediately problems started..i cant be sure it was the tap water but the problems stopped once i stopped giving them tap water.
mystery..cover your bucket with some sort of cloth or something so leaves and things dont end up in your water

In most populated areas, rainwater contains pollutants and may be slightly acidic. Regardless of where you get your water, you need to balance it so it has a PH of between 6.2-6.8. You should also be checking the electrical conductivity with a meter that measures PPM. The closer to 0 the better. I use purified water that has an initial PH of 8 and measures 130ppm. I add my nutes, bringing it up to 800ppm then balance it down to a PH of 6.3.

I was thinking about getting a ppm meter even though I dont grow hydro (next grow) and I bet it can aid in my soil grow right?
They're just so damn expensive.. I found my ph meter for 30 on ebay
Jollygreen - Yeah i covered it with a towel outside so there should be no leaves..
Can I transplant before 12pm (my plants off period) tonight with the water that is slightly chlorinated without effecting my plants?

A PPM meter is not just for hydro setups. Regardless of your grow medium, it is important to know the specs of your water. I got a nice Hanna multi-meter that does PH and PPM for about $200 from HTG.

Your right...I know how they work..Just seems like alot of work but i'll need one to measure my nutes anyway
Will using tap water that has been sitting out for 5 hours mess my plants up though when I transplant them?
Lol I already know im hardheaded
but these roots are coming out of the fucking party cup holes bro

I've never had any problems using tap water even strait from the faucet, but my city has one of the top rated water treatment plants in the country so that could have something to do with it. Also it probably depends a lot on what strain it is some strains may be more sensitive to such things. I usually fill up a few gallon jugs and let them sit for atleast 24 hours, but letting them sit wont do anyhting if your city uses chloramine instead of chlorine because it doesn't evaporate.

So if people arent using tap water for their plants what are you guys using?

I had always used tap water but I used a tds meter. The water was about 380ppm but the pH was almost at 7.0. I mostly used Fox Farms products so the pH was just right after getting the ppm correct. I used 800-900ppm for plants in soil and about 1200ppm for the hydro. Then again I raised or lowered the ppm for the hydro depending on what they were at before adding more water in order to keep it stable. I may have to recheck my facts because this was over 2 years ago and I could have my numbers backwards.

My water company uses CHLORAMINE instead of clorine in tap water and it does NOT evaporate and causes big problems for water grows.
Lots of municipalities are using it now. Know whats in your water.

both are kinda whack, tap water and rain water varies ALOT depending on the area with you live...
for $5 at my local store i can get a 24 of 1litre water bottles, perfect ph and 0ppm this way i can easily standardize my feeding regiment
also u can get PH strips which are mad cheap...ph readers are way cheaper at home depot and nurseries...
head shops jack up the prices on "specialty items" which a ph reader definitely is not.
