For the purposes of hydroponic gardening, it’s very important we use high quality water. Unfortunately water quality can differ depending on the area you live in. For example, if you live near the coast you are much more likely to have higher sodium content in your water supply. Using water with too much sodium in your hydroponic garden can have many negative effects on your plants. These include brown looking leaves due to dehydration, stunted growth and in addition, your vegetables may taste really bad. Fortunately we can fix these problems by use of a reverse osmosis filter system. I’ve tested out the Watts Premier RO-Pure 531411 4-Stage Reverse Osmosis Water Filtration System and here is my review of the product!
Why Hydroponic Gardeners Need Filtered Water?
Well in actual fact, not all hydroponic gardeners will need to filter their water. In many cases your water will probably be fine to use straight away in your hydroponic nutrient solution! In which case there’s no reason for you to be reading this review.
However, if you’re like many people and your drinking water does not come through the faucet at the desired purity then using this water for your hydroponic plants or for drinking yourself could be disadvantageous.
So what is the desired purity and how do you discover the purity of your water supply?
For drinking, you want as many of the dissolved solids in your water removed as possible. The purer the better, although many may disagree which is why fluoride is often added to drinking water. For hydroponics then i would not recommend you ever use water that has a dissolved solids content greater than 300 parts per million (PPM). However, you should ideally be aiming for water less than 150 PPM. The solids contained in water often include calcium, magnesium and sodium. In fact sodium can be so dangerous to your hydroponic plants that you should ensure the sodium content is below 50 PPM.
By using a high quality EC meter you can accurately measure the content of solids in your water.
What is the Watts Premier RO-Pure 531411 4-Stage Reverse Osmosis Water Filtration System and how does it work?
It’s a high-tech water filter system that operates in four independent stages to filter your water. It uses a technique called reverse osmosis to remove all dissolved solids, turning tainted water into clean water.
Reverse Osmosis – Stage 1
Five micron sediment filter – This is the part of the process that removes all the big stuff that comes up through your pipes. Stuff like dirt and rust that can so often discolor your water supply. Getting rid of this will completely alter the look and will remove not only large parts of invisible dissolved solids but also those solids you can see too.
This is the blue filter on the system that you’ll need to replace once a year.
Reverse Osmosis – Stage 2
Five micron carbon block filter – The Watts Premier RO-Pure 531411 4-Stage Reverse Osmosis Water Filtration System then removes all traces of chlorine and fluoride.
This is the green filter which needs replacing less regularly than the other filters. Expect to require a change between every 3 and 5 years depending on usage.
Reverse Osmosis – Stage 3
Reverse osmosis membrane – This is where the magic happens. Stage 3 is the larger part of the process where the vast majority of impurities and dissolved solids are removed from your water. This includes all the sodium in your water supply that can give you kidney stones or at the very least, seriously harm your hydroponic plants. Other things that are removed in stage 3 include; lead, arsenic, copper and radium.
As soon as stage 3 has been completed, the water stores in the storage tank. One of the only complaints with the Watts Premier RO-Pure 531411 4-Stage Reverse Osmosis Water Filtration System is that the inside of the storage tank can occasionally taint the water. This hasn’t been the case in the vast majority of cases and in any case, if it does happen, you can get a free replacement by calling the customer care line.
Reverse Osmosis – Stage 4
Post filtration – The fourth and final part of the filtration process only occurs when you turn on the faucet. This final part is similar to using a Brita water filter. This filter needs replacing ideally every 6 months.
What was the result of using the Watts Premier RO-Pure 531411 4-Stage Reverse Osmosis Water Filtration System?
The vast majority of reviewers of the Watts Premier RO-Pure 531411 4-Stage Reverse Osmosis Water Filtration System have had great results, with one tester lowering his solid content from 370 PPM to 18 PPM. This is an incredible reduction to the extent that you can have incredible tasting drinking water or hydroponic nutrient solution.
My starting point was not quite as bad as 370, being a paltry 230 PPM. Using my trusty EC meter, i recorded a resulting reading of 15 PPM of dissolved solids. I am of course very happy with this result.
Other things to consider with the Watts Premier RO-Pure 4-Stage
Installing the system – It took me nearly two hours to install my system underneath the kitchen sink. The instructions aren’t great but they are adequate. If you have any plumbing experience then you’ll find it very easy. If not then please ensure you keep plenty of towels to hand and maybe even a bucket in case you have any accidents.
Price – The Watts Premier RO-Pure 531411 4-Stage Reverse Osmosis Water Filtration System is not cheap. Depending on how often you use it however, you will recoup the initial outlay eventually with not having to buy bottled water ever again. The cheapest place you can find it online is Amazon! Please note that you’ll need to pay extra for shipping.
