Setting up A DWC: Deciding which Water source to use
I am still deciding which water source I should use for my DWC. I have access to Tap water and Distilled water. It would be difficult to set up an RO water system. But it is a possibility

Setup: 5 Gal DWC Single
Nute Forluma: Lucas Formula

Water Sources:
Tap Water Test Results: (700 PPM scale)
PPM: 98
PH: 7.2
Temp: 70

Is my Tap water good enough to use along the Lucas Formula and a DWC?

Thanks

98 ppm ain't bad. But why is it difficult for you to set up an RO? Just buy one and hook it up to your kitchen faucet. It requires no special installation, and you will grow with much greater success and confidence.

I've noticed that many of the beginners who encounter problems early say things like, "I don't have a ph meter" or "I don't measure my ppm" or "I'm just using tap water."

It might be okay to use.. if you lower that ph almost a full point. Maybe more..

Better than ROing is knowing what's in that tap water! Hook up with your water people and ask for an analysis, they probably have it online somewhere.

You're lucky. You live in a pretty good water area wherever you are.

Edit: Oh, Netherlands. Sorry. Wait a minute? Netherlands? Yeah!

Edit 2: But watch out master breeders and growers in the Netherlands, California is coming for you! And that goes double for you, Canada. Lol.

thanks for the input everyone.

Well, I am still deciding, I am still trying to figure out if I need RO if my PPM is 98...
It's a difficult decision. It obviously would be the best thing to do.
Can I get away with 98 and have a successful run?

Hey, man. I'm an RO freak. I'll just say RO to anyone. Some of these other guys sound like they know what they're talking about, so I don't think it would hurt to listen to them, either. Again, from what I understand, under 100ppm tap is on the cleaner side of things. But like someone else said, it would be wise to find out just what that 98ppm is if you can. If not, just filter it out and forget about it.

The thing is you do not know what that 98ppm comprises of. It could and prob will work fine but then again it might screw with shit. I agree using r/o just allows you full control of what is in the water giving you one less thing to question when shit hits the fan. I got r/o at the very start of my growing career. I bought it for ~$100 and used a saddle value to hook it to the standard 1/2inch copper running in the basement.

edit: one more thing to note is if the r/o comes with a pressure tank it must be hooked up to it. The r/o machine will not shut off properly using a float valve without the tank.

you should be able to successfully grow with anything less than 150, my ppms now are higher than yours and i do fine, the problem lies in what makes up that 98 ppm. water impurites are area specific, and some additives could kill your bud, find out whats in that 98 ppm and you should be good. but if i were you id try it with a single plant first and see how it fairs

Yes, it could be 98ppm of mercury. No, just kidding of course.

But it looks like it comes down to obtaining detailed water analysis info or spending 100-200 (US dollars) for RO and growing with a 'blank canvas.' I say if you have money to buy the filter, buy the filter.

I think you have pretty good water but like VoidObject said it would be best to know what was in it. I live in North Texas. The water here smells bad and has crazy high PPMs out of the tap. The water turns off for several hours at a time every few days, its a tiny town in the middle of nowhere. I was not drinking nor giving this water to my plants or dogs and I was spending $20 a week @ $.25/gal on water. So I bought a 100 gal/day RO from the hydro store and its already saved me money. best investment I've made in a while.

Exactly. Los Angeles water isn't the best either. I get like 200-300ppm. Yuck, what is that? It smells bad and tastes like pipe, too. You should just see the crud my sediment filter collects... a rusty, metallic, mineral buildup. And when I finally change the filter elements, the dirty filters smell like a sewer.

And yes, completely aside from pot-growing, it's a great source of drinking water for yourself and your pets, saving you a lot of money in the long run.

You are welcome to the Holland anytime.. WE are located 30km south of amsterdam, very chill area, no tourist. I work in a coffee shop. We have good quality. I am learning everyday.

RO question:
I am worries about installation.
Which is a good RO that I can just hook up to my Tap faucet?
Any recommendations?

Thanks from holland

I would love, love, love to take a trip one day. Not to touristy Amsterdam, but a town like you describe. But Since Amsterdam is close by...

Here is a picture of my ro filter. It requires just that simple faucet attachment that diverts the pressure from your tap faucet into the RO's feed tube. Just pull the button for ro, push the button for regular tap water flow.

You will have a great time here in Holland, You are welcome any time, anyone form the forum is also welcome.

So that looks like a 3 or 4 stage system?. what is the difference between the 5 stage ones?. I don't care for drinking either

Thank You

Yes, mine is the standard 3 stage configuration: sediment, carbon, and membrane. The membrane is the most expensive element, but it's the one you change the least often. The sediment and carbon elements are like 10-15 (US) each, and they last for many months before you have to replace.

You have pretty clean water. You don't need those super 4, 5 stage filters. You might even be able to get by with a smaller 3 stage. (smaller than my unit, maybe 50gpd, and cheaper).
