Is this water safe for RDWC? Water quality results!!!

Honestly looks like typical tap water.... As all tap water I would recommend letting it sit out for 24-72 hours prior to use... though this method to many is to let chlorine evaporate, some other items actually do break down during this time.

You should be good to go!

Not sure what's good and whats bad in this, kinda need someone who has knowledge in this area. I work for a local water company, but not in the lab. Anyone?

Hobgoblit: why not ask the guys in the lab? If you work there they'll likely be able to tell you. Just don't tell them what you want to grow. Tell them you want to grow culinary herbs hydroponically in an Aerogarden. Worked for me. They told me to use bottled water. HSA

I'll make a trip up to see a buddy of mine, and see if he can get one of the girls in the lab to look at the printout. I'm very sure it didn't leave the plant this way, alot is picked up along the trip to my house.

Those results are definitely just typical tap water. Totally safe for consumption or any hydro. Everything is in ppb (parts per billion) or ugl, with the only exception being the nitrates expressed as ppm or mg/L. Looks good to me (and I also work in the water industry).

These are just the chemical results of your water. I would be much more concerned with TDS and alkalinity, than any chemical or microbiological analytical results.

I just have to chime in the Cl2 issue as well.

If you use tap water yes let it sit out for 24 hours so the chlorine can evaporate.

I completely disagree with having to do this. Cl2, in the amounts applied, is completely harmless to plants and people. If your local utility uses a "free" cl2 type system, then would likely see a free residual at your tap of around 1.00 to 1.50 mg/L. However, if the utility uses Chloramination(which is becoming increasingly popular) it will not dissipate. Just my 2 cents.

I also disagree. I long gave up letting water sit out overnight and noticed absolutely no change in results. If you can drink it you can grow with it, that's how i tend to do it.

Why is there chloroform in your water? I'm doing some reading but it seems only explanation would be algea in th water :/

We use chlorine injection. Dangerous, but effective. TDS from tap is at 035.

Do you mean 350ppm? or EC? Either way, that is almost perfect "starting" water in my books., just the right amount of hardness. I know that DNF nutes uses 300ppm base in all its feed charts.

Looks like you got great H2o my friend!

Nope, 35 PPM, straight out the tap. Think I'll still be buying that R/O system though, something in it is giving me fits, and it always happens when I use this tap.

I live near east bum f**k though, nearest walmart is 30+ minutes away. Nearest home depot is 40+ minutes away. $1.20 for 1 gallon of 0-.5 PPM water is pro x37
