Choosing water

I am looking for other options cause Right now I am going to a cullagin jug refill and paying for water. i am in town and also have access to well water at my farm I am trying to figure out which would be the better choice for mixing my nutrience with. Is their ways to test if one is better then the other ?

well water should be ok, what ppm tds is it? and what ph is it. need more info on thewell water, im not familiar with that brand of water so couldent tell you

A total dissolved solids meter or TDS/EC/PPM meter will give you an idea. If the water is high PPM you may want to send a sample to a lab to have it tested so you know exactly whats in it.
Do you know of any home test kits ?i sent it to a lab and they didn't really give me much info other then ecoli and nitrates

Last time I did one was like 14 years ago and I picked up the vial and mailer at Home Depot. Collect a sample and mail it in. Got back a good report with the mg/l numbers for all the elements they found in the water.

There are water hardness tests for aquariums. Right now I'm using one of the cheapo vivosun tds meters from amazon, got it for $10 I think. It seems like the cheapo tds meters are more reliable than the equally cheap ph meters, but I would double check the results at first anyway. Do check your well water though, it may be perfectly fine.

So we have checked the town water and it running about 530ppm and 7.1 ph our well water is really high ppm at 1580 and 7.2 ph .
We have been looking into ro systems as both ppm seem to high I am wondering what everyone is using to for filters and ro systems not looking to spend alot of money.

proper ro systems have a waste line. that kinda screwed up my plan. i just got an in-line filter & brought my ppm down from 350 to an avg 30. it has standard 1/4” compression water lines & went perfectly with the ice machine water line tap thingy i got. doesn't change my ph by enough to help/hinder. the filter only claims to “diminish chlorine taste & odor”. well, i just know i needed a closer water supply, because carrying around 5+ gallons of RO from the local ice machine & down where my stashed flowering room is? that was for the birds! i think you do the best u can with what u can get. i’ve hobbled together a small grow that still isnt quite ideal, but my buds sure are! an ro system might still be in my future. so keep me posted on how it goes. i just suggest u go ahead & use what u got. making improvements, sure. but get er growin! best of luck

so stoned. i meant to add... try the two options. see how the girls react. u very well might have something good in one, or both of those waters! try them & see! my little filter things seems to treat my girls better than when i was lugging water

Like @Renfro said you are looking for what is in your well water. If you have TDS over 300 RO it. If it's under that send it to test. You want to watch out for high levels of Fe.

Chlorine is great, chloramine isn't. I run off 250 PPM chlorine based city water and my plants are happy. So if you have good city water use it

As for RO you'll have to research it yourself. It depends on your GPM, how many gallons you need etc....... I think mine is a cheapie 3 filter Hydrofarm. I don't use anymore it because my tap works great.

Ya that is what I thought when I stuck my ppm meter in it that don't seem like the greatest water to be growing on when trying to add fert.
Did the meter stand up on it's own in that thick broth? lol

If you use an RO filter you probably want a prefilter to knock down the PPM before it hits your RO sediment filter. A large sediment filter before the RO filter will probably save you from changing the RO pre filters as often. Of course you would have to replace the pre-filter on occasion but if you get a large one it will go longer between changes.

With RO filtration you really need some pressure. The difference is huge, like if you are at 40 PSI compared to 70 PSI it might take 4x as long to produce a given amount of filtered water AND low PSI increases the amount of water wasted as brine to produce that filtered water. In most cases, folks with well water will require a booster pump on the RO filter input.

If you do want to get into filtering the well water I highly recommend contacting WECO. They can help you design the best system for your situation. If I had water that hard I would want a whole house filtration system honestly but they are costly. I bet you get a lot of buildup on shower heads and such. I remember helping my dad replace the old galvanized iron water pipes in his old farm house. Cutting a one inch ID pipe would reveal buildup that only left about 3/16 inch opening through the pipe. Talk about clogged arteries lol, house needed a quadruple bypass. New PEX water distribution lines eliminated the potential for future calcium buildups in the pipes.

The crazy thing is it is really good drinking water and super easy on the house . I am think more an ro system on my house in town as water is only at 530 ppm but we are only powered by a water tower and I think only have 10 psi
