high ppm tap water

i took a bottle of tap water to a hydroponic shop today to have it tested this is what his meters readView attachment 1277534. have any of you used tap water with such high ppm? how did it turn out? the owner of the hydro shop wants me to do a side by side. 1 plant tap water 1 plant spring water to see how they turn out with such high ppm.

Thats not that bad. I have well water and it is over 200.

I would recommend NOT using spring water. no telling how much dissolved minerals are in those. If you want to buy water, by Reverse Osmosis Water. Every grocery store around my area sells it. 80cents for a new jug, 49cents a gallon for refills. But I would just use your tap water. It's a bit high, but shouldn't cause any problems.

Tap water has alot of benificial micro nutrients in it also.

My tap is 600+PPM. It seems fine for me. I also have a RO system but started back on tap to save the cost of Cal-mag type supplements.

I'm currently using plain tap water with a base ppm of 410 +/- 20, and my ladies (atleadt I hope they are ladies as they just enterd the veg stage recently) don't mind one bit, now my ph is around 8.0 so when I use ph down my ppm will obviously jump to like 600ppm or so and all is well, I only have a bit of burn on 1 of them because I'm starting to use nutes and trying to find out what they will tolerate.

you guys really grow your plants with that hard of water? the guy at the hydroponic shop had never seen over 350ppm brought to him for tap water. i wont even drink my tap water because of how hard of water it is and it taste like crap.

@jason morgan,
I can and has been done with hard water for many, and many have been unable to. At times I do switch to RO and then back to tap every other res. change. IMHO, I don't think it is really the high PPM from the tap but what is actually dissolved in the tap water. That will differ from town to town and well to well.
I have heard of people using those cheap camper water filters that go inline with a garden hose to reduce the PPM. They are not RO filters but will catch some of the crap. I use two together to fill my hot tub because unfiltered water will leave a white powder on the bottom after 24-48 hours. We don't drink the tap water either because it is just under the FDA's PPM limit for safe water. I use my RO machine to re-fill my water cooler jugs for drinking water.
Many say not to use water that has went through a water softener due to the amount of salt that gets in it.
I will say between RO and tap water, tap takes a hell of a lot more PH down than RO does to adjust and maintain.

something I haven't seen here. Are you growing hydro or soil?

right now they are is soil in the small plastis cups. but im not sure yet whether im going to transplant to soil or to coco coir yet. my water is more calcium then sulfur by my guess.
