No ones municipal tap water is this low. So many bs ers on this site it is not even funny. The question is if you are worried about the sterilizing agent from your water authority. Call them and ask them what they use. Simple and then u will know one thing. That one thing is if the agent will dissipate and well most use good old regular Chlorine. I could not care less if it is sat out or not. I can drink it and not die and I assure u a weed won't die or even feel it either way. As for hard water or not, I have 220ppm straight from the tap and I just add my regular nutes to the level I am shooting for with the tap water as a total. Do not remove the ppm # from your nute formula. In other words the total is the total after u put in your nutes. Tap water works great and if u think I am wrong and you want to be one of the veggie tarian food organic only types and waste tons of money, time, and effort for perfect clean cloud water then waste your money on an ro filter. or bottled water or whatever. It makes almost no difference and I have grown over 16 strains and over 3 years of every 2 months harvests. But I am most likely wrong. Sure.... My colas are the size of my forearm and I am big. and of 4 plants I grow to flower each cycle I get over 20 zips and that is under one 1k hps with 1k more added at day 35 of flower and they finish in right at 55 days. I use a mover for the one light then I put up the other and stop the mover for the finish. IF you think u can do better then u are smokin my stuff. LOL.:hump::joint:


Here we have very clean tap water. Right now it is coming out at 30 ppm which is essentially RO water. I have never let the water sit out. Chlorine in the amounts used in municipal water will not harm your plants. It is beneficial in DWC systems because it sterilizes.

If you have municipal well water watch for nutrient deficiencies down the road. A lot of deep well water contains exotic minerals that can lock out trace elements. You might have to run an RO filter on well water, even if it comes out at low PPM.

Not sure you want to go weeks between change outs running DWC. I wouldn't go longer than ten days between change outs.

I will check out your recipe as i just picked up some pure blend pro.

Also, the tap water probably does contain more ppm than 30ppm. I forget the process I was going through when i was going over my water quality.
It can't be in the 200ppm's because my ppm reader says 0ppm at a 700 conversion rate.

Tap is perfectly fine to use. I got suckered into running R/O water in the beginning. It starts to get a little costly so I went to tap. I figured if you can water house plants, as well as any other plant in the world with tap water and have no ill effect then it's not going to hurt the ones you are growing. I even started letting the water sit for 24 hrs to let the chlorine evaporate out, but now I don't even do that. I just hook the hose up to the faucet, put the other end in the res, turn it on and fill the res up. Haven't had any problems with it, and it saves me a ton of money and time. The very small amounts of chlorine that's in the water won't hurt the plants or roots. If anything it may, and I do say MAY, help keep any nasties away from your roots, but I haven't seen any scientific proof that it does, but I just like to believe it can help a little bit. Sure, they say no to use beneficials if you don't let the chlorine evaporate out. I'm sure that is true though, that's why I wait about 2 days before putting any beneficials in the res, just in case the chlorine does kill them off, and those benies sure aren't cheap.

Don't buy the hype of R/O water. The only thing that is good about R/O water, to me, is that it's a clean slate, and you know exactly what is going into your res. That part is nice though. Using R/O water they say you need to add Cal/Mag, that's another thing that you have to buy and waste money on since tap water typically has enough of both for your plants. So you don't waste money on buying cal/mag all the time.

I use well water that is around 250 [email protected] and yes it does take a bit of down due to buffers but once i figured that out no issues. Lots of people on many sites led me to believe i could never grow in that "hard" water. 2 grows in and 600 grams later doin ok lol.
