Reverse Osmosis System PPM

I have 2 garbage cans full of rain water, sometimes they sit for a week or more.. My rain water is 12-18 ish ppm ..I mix in my well water 445 ppm to get it 125 ish. Got buckets frozen outside of rainwater ..I bring em inside and 30 hours later they are melted..never seen any water go bad ...but it evaporates quick if you don't cover the top.

Most peoples water is not the same as far as content, My personal experience is with R/O water and straight tap water from a community well. I was using R/o for a long time in Hydro and it worked well adding to it nutes ( GH 3 part stuff). Then lately I went to Organic soil and had to add different nutes for different plants It was hard to do. I then quit using R/O and used straight tap water @ 96ppm. The results were welcomed I rarely add any thing except Organic Mollasses and of course super soil mix. I don't think that this will work for everyone but it worked for me.

So I figure I could just buy a lid for the buckets and maybe it can sit for 1 or 2 days?

I fill 5-gal jugs at the dispensing machine (at the grocery store). They sit for 2-3 months sometimes. (I'm not fastidious about rotating them. Sometimes I'll refill a couple and use them before the others.). However, I believe the dispensing machine uses an ultraviolet light to sanitize the water.

A couple weeks for household-produced water should be fine.

my ro unit needed a break in period so to speak...it started around 50ppm and after about 50 gallons it dropped to 10-15ppm. the manufacturer said i would need to run around 100 gallons for it to break in.

Anyone vouch for a cheap ro system under 150$ ?

I spent a lot of time looking at them. I ended up deciding this Watts WP-5 for $160 US was about the best. I never bought it, so I can't vouch for it.

However, if you stay with a modular system like that, they're all about the same. You can use anyone's filters in that. You can replace parts, etc. You want to stay away from the proprietary manifolds which can lock you into a brand.

(For example, look at purewater4u [dot] com. You can buy the hanger bracket, individual filter canisters, and make your own. It's all the same stuff. They have some pressure gauges which help you see if your filters are clogged. Also clear canister housings so you can see what the pre-filters looks like.).

RO buddie. 50 Gpd and snaps together in 5 minutes and you're making water under 10ppm from 360 starting. 1/2 hr/gallon. The sediment and carbon cartridges are good for 1500 gal. Amazon for under $70 bucks, perfect for the home grower using coco or hydro. 4cc/gal using floranova bloom=700ppm every time. 1cc ph up = 5.8ph every time. RO is great for repeatable results every time and that's necessary for coco. Tap and ph will always fluctuate before it finds a home. Your results Depend on what they use to stabilize THEIR pH before discharge. No beef with tap here I still use it just not in coco
