What's my best option for buying water?

I am not even going to consider using my tap water,I have very hard water,which is treated with lots of salt.The only way I will use it is if I end up buying a RO system.
Ya if your water is high PPM you probably need a RO, but honestly u are putting this water on dirt.....not like you know exactly whats in the FFOF to begin with....i venture to say growing in soil you will get the same results with 300 ppm base water as with 15 ppm base water. Bu8t if your water is like 500 u may need a RO.

Your recommendations are good, but this part is spurious. This is not how municipal water systems work. Not sure why I care so much, except this sort disinformation is insidious and gets people's minds twisted into believing things that are misleading. You can trust the tap in Fort Collins, CO, for instance, that's some near-RO quality water.
Add minerals? I think your thinking of how the water district and distribution works is off. The water i have in San Diego is 500-600 PPM, this is no because the water district made a conscious effort to add minerals. The reason our water is so high is because it has a lot of dissolved solids naturally and it would be too expensive for the district to filter it out. The water district makes sure you have safe drinkable water, but the allowable limits of dissolved solids is like 500-600 so if its under that that's what you get. Certain parts of the country just have water that is cleaner and has less sediment.

I have been buying RO water at Walmart for a while,but the machine has been out of service for a while.They also sell "drinking water, spring water,and distilled water" in gallon jugs.Which one of those would be best to buy for now until they get the RO machine back in service?I have well water that goes through a softener,so I know I am better off buying water.I am growing in Fox Farm soil.Also,will I need to add Cal-Mag to all of those options?
Best option is to not buy water at all & use reclaimed water from a clean dehumidier set up near your grow areas. When you know it's gonna rain put buckets out under gutter downspouts or awnings to collect it. Free clean water is the best to use. If you use reclaimed water which is basically distilled it will have low ppms so you'll need to add cal/mag in low doses but rain has macros as well as microbial life; use it as is. I still sometimes need to trek down to walmart for their RO unit but I can supply most of my grows water needs with just a dehuey and whatever rain I can collect when it does.

I bought one of those "PUR" filters that snaps on your faucet.. I bought the best one (theres like 3 models) It seems to do well for me. I've never ph'd anything in my life so i couldnt tell ya the ph.. I do however collect rain water when it rains then I will put an airstone in it for 24 hours... hell i always put an airstone in my water for 24 hours before i water.. sure maybe it only adds a tiny bit more O2 that gets to the roots but the more the better IMO.

Have you tested the before and after EC? Doubt there is much of a change but curious.

I just checked my softened water with a Britta filter,
345 ppm bypassing the filter,and 395ppm going through the filter,how is that possible?I even double checked the readings to make sure it wasn't a fluke.

Yes of course if you live in the desert forget everything I said & Walmart is your freind. You can get RO units that will hook up to your garden hose around $100+ but they are super wasteful...had one but it blew up from extreme cold last winter; always store dry in the cold weather lol

Not sure, I do know that they are basically a particle filter that has no ability to grab any thing that would raise EC re salts

all RO filters are wasteful as hell. They use water to clean the filter so its takes like 5-6 gallons of water to make 1 gallon of filtered water.

I'm looking at Nu Calgon system and it seems it just cartridges and no waste :). Going to call wholesaler tomorrow and see what prices are like .... Expensive I fear lol.

R/O can be set up for 1:3, 1:2 or 1:1, clean:waste. With tap at 500ppm or higher, the advice is to use the 1:2.
1:1 is for really soft water. You can also use the 1:1 anywhere, your filter will need to be replaced quicker. Not a bad thing.

Man where are you getting your information? 30 years ago they were not very efficient, but no longer. If you have a RO with a pump, rejection is ~ 1:1. A single shower wastes 10xs+++ more than that

It's 3:1 and 1:1 if you put in the restrictor. Our "waste" water is diverted to animal use. There are ways you can redirect the waste water for home use too. Tanked and used for toilets by specific connection. Lawn and garden use, etc.....It's up to YOU to change your world - Not complain about it!

GREAT point on the shower! Beat me to the RO point too!

Mine is like 15 years old, but it def uses way more than 3:1, must be cuz its old.

do they still get the PPM as low if u use 1:1?

If you go looking to buy a RO filter u can still buy my exact filter that takes at least 5 gallons of water to make 1 gallon clean, so its not like i was making some crazy statement, tho glad to hear newer ones arent so wasteful.
