Explain its value? ro water is almost a pure as distilled. it is the best starting point for hydro because you know your starting point is zero and you can better control from there. Plus it is better for drinking, coffee and tea etc. I wouldn't be without mine.

what are the pros and cons if any. what are the specific needs when using ro so on so forth BTW it's just as much work for me to use the filter as it is to carry water from the store except i have to wait for the final product. but will deffinately save me money in the long run. Do I need to get some calmag or magical.

I used to carry water from the store and I thought that was a lot more work. I figure my ro unit which was $179 paid for itself in 6 months. But then my wife and I both like it for drinking.

same here the fam likes it how long can you store R O water and does it have to be completely sealed or what i'm confused and the manual don't say nuthing.

I don't agree with this. Distilled water is what all other waters are measured against. Distilled water is almost 100% pure.
Your RO water is around 95% pure.

Which unit are you running?
Would it be this one?

Maybe your ro water sucks but mine is less than 10 ppm.
Mr.Bob Saget

Your missing my point, and seem to be offended.
I bet it is 10ppm. Distilled water has a EC of 1 or 2. I'm not sure which conversion you are using to PPM, but as you can see by the EC there is nothing in it.
Your 10ppm could be an EC of around 100.
I too want a RO filter for the convenience, the one I put in the link above is what I was looking at.

There are def more pros than cons if using a RO ill start with the cons first. Waste water RO literally throw away 2/3 of the water they take in and if your doing a larger size grow thats alot of water to just dump it seems like a huge waste especially if your on a well or something the second con would be the time it takes to get the amount of water you need oh so you want to water yeah well your gonna have to wait 4 hours to fill up your reservoir at minimum oh wait you have a 100+gallon reservoir well ok ill see you tomorrow lol. The third would be price.. those thigns are expensive ecspecially if your looking at one that does more than 200 gpd your talking thousands.
Ok and the Pros now. First you dont have to lug car fulls of water every 2 days from the grocery store looking like your up to something even though you said its not a problem no body need 20 5 gallon jugs of water unless of course your getting ready for a fall out... it just looks suspicious and anyone who knows whats up will know exactly what your doing. Second they really will pay for themselves after a few months. The pre filters need to be changed every 6 months to a year and thats pretty minimal ($40 maybe) the membranes last about 4 years and those are expensive so if you machine is that old you might as well just buy a new unit by then. Third you can regulate the exact amount of ppm you are giving to your plants some places especially growers with well water will have high ppm to start with and it will total mess with your nutrient regimens and could cause toxicity problems depending on what mineral is too high in the water to start with. Forth if your on city water chances you have chlorine in it and that kills all beneficial bacteria in your soil and/or growing media it totally depletes you little mini Eco system you basically need in your root structure

Good info + rep for somthing stuctured and informal. Did not know about the clorine killing the beneficials. Deffinately good to know. My res runs 16 Gallons for six plants in a 31 gallon tote why 31 and not just 30 I have no idea, but so far so good. anyone else have any extra info on this subject. I would really like to know if i should pick up some magical or calmag whatever booster i go with. Is it a neccessity for Ro or will I be able to squeeze by with my GH three part I'm also using floralicious, and subcultures.

In my avi is my set up. 4x8 tray, 70 gal res, sealed room and so on. I do have an RO set up. It takes 12 hours to produce 70 gallons.
It is nice to know that you have a clean slate when mixing your res up. My water is 500ppm out of the tap and very hard. So RO is almost mandatory for my hydro grow. My soil grows were fine with tap water.
I pretty much run your basic NPK nutes and a half dose of CalMag. Most nutes have some CalMag in them and that's usually enough for growing herb. My RO system takes my ppm from 500 down to about 10. One thing to consider is an RO system with a reserve barrel. It is sort of a bitch to clean your res if you don't have 70 gallons waiting to go in. If you fill up your res directly from the RO and forget about it you will have a flood. A few gallons of water on a floor is a ton of water. Been there...
Get an RO system and a reserve barrel with a float. You can turn on the RO and when the barrel fills the float rises and shuts off the RO system. It works like the float in your toilet.
$200 is the price for a decent RO system. Buy a used barrel on Craigslist. Some hydro shops have them too. For under $300 you can have really good water.
If you're going to grow in soil don't even worry about RO, just grow.

RO is the way to go for Hydro you spent your money wisely!
True you have waste my system is 5 stage with Deionization my waste is 2/1 two gallons go down the drain to get one.
I get 3 gallons an hour and have a 20 gal holding tank with a float. My EC going in to filter is around 900 coming out .15 Pretty darn pure and better then trying to find distilled and lugging it from the store plus throwing away all those bottles raises eyebrows also the distilled water I was getting has an EC of .20 -.50 I think some water companies are just bottling filtered water and calling it distilled.
You will need to add back the cal/mag since the filter will strip the water of almost everything and most nutrients don’t have a lot of cal/mag I use GH Flora series for my nutrients never had a PH balance problem and my plants go wild with the new water.
Best of luck with new system

Anyone considering going to RO check this place out best price I found far superior system when compared to what the growing supply sites have 159.00 75 GPD RO/DI 5 Stage Standard System plus they have cool videos on how to set up system

Anyone have feedback on this system?
I'm having a hard time find hard numbers on this system.
That web site has the cheapest system I have came across.

Damn that's cheap guess I should've posted this thread before shopping Oh Well I got a pretty decent deal at the grow store and I like to support the cause if all the grow shops went broke we'd have to order out every time and that can be a hassle when you want it now. I have the Hydro Logic stealth purification system 100 GPD a day which is ok I have storage totes that I fill with about 8 gallons a peice and then I have to carry those upstairs and pore into my res Only have to do this twice and it took me about ten hours. so far so good I love it. What do i do with the water that's left in the filters. do i just leave it there or do i have to unscrew the housing and pour out, the directions say nothing about it they probably think i'ts common sense, but not to a noob to the whole thing I hadn't even heard of RO water till I stumbled upon growing. Now I'm starting to get the hang of things still tons of ?'s, trials and errors, and before you know it i'll be 50 and a pronounced professional marijuana grower. thanx everybody for the convo keep it up I'm sure there is plenty more to know about RO Water such as how will affect the Taste of your final product?

Mr. Bob using the system for 6 months works flawless.
I think the price is lower because its a salt water fish supply not a growing supply
Growing supply shops tend to inflate prices due to the nature of the business
Both R O systems are the same in working principal really even better filtering 5 times to some of the grow shops 2-3 filter systems.
algeezy sorry to post the R.O recommendation on your thread just thought it would help out others looking for one It took me a year of looking before I finally bought one. didnt mean to make ya feel bad since you already have one... Have a bong hit on me
