Gard’n Gro Garden Filter review and giveaway


As I have mentioned on my post on watering, I like to dechlorinate my water by filling 5 gallon buckets with water and letting them sit overnight.  Though this year I always seemed to not have enough time (or foresight) to be diligent about this and ended up just dragging the hose out and watering the plants chlorine at all.

Fortunately our friends at AllFilters have a solution to this problem with the Gard’n Grow Garden Filter, by simply adding this small inline filter it can remove at least 85% of the chlorine in your water without needing to prefill or carry around heavy buckets.

After opening the package the installation process was a piece of cake.  You simply attach one end of the hose to your outdoor faucet and the other end to the filter.  Attach your garden hose to the other end of the filter and turn on the water.


Now to test this thing out, unfortunately I don’t have any equipment to test for chlorine, but given I am under city water I can smell the chlorine pretty easily.  So for my first test I went with the very scientific smell test and confirmed a huge difference between using the Gard’n Grow Garden Filter.

To try to redeem myself a little more, given I had two cups of water I was sniffing anyway, I put my TDS meter (which for non hydroponic readers measures the total dissolved solids in the water) and though this does not measure chlorine specifically it does pick up various salts in the water.  Actually to my surprise there was a significant difference between the filtered water and the water straight out of the tap, given this benefit was not mentioned in the Gard’n Grow’s literature.  With the tap water the reading was 38ppm and the filtered water 33ppm.

Last the instructions mentioned that you may have a slight reduction in pressure after installing the filter.  Now this is definitely expected, but I needed to confirm how “slight” we are talking here.  For this I did the 5 gallon fill test.  For the unfiltered test I was able to fill the bucket in 71.6 seconds or 4.18 GPM and the filtered test finished in 79.9 seconds or 3.76 GPM.  Though this is a reduction of volume of about 10%, given my small garden I don’t think I would notice the extra 8.3 seconds I would spend watering.

Overall I was very impressed with this filter and am looking forward to using it to fill my reservoirs for my hydroponic experiments this winter and my garden next spring/summer.

    Never really considered issues with chlorine in my water, but now its something Ill pay attention to…

    Very interesting. . .

  7. Keith Says:

    Sounds like a nice product!

  8. Lynda Says:

    Sounds like a very good idea. Question however, how long does it last before you have to replace it?


  9. The Cheap Vegetable Gardener Says:

    Lynda, good question. I meant to put that in the review (will add later) The filter is good for 20,000 gallons, you can also flush any sediments out by running water in the opposite direction.

  10. Hello_Kitty_ Says:

    This would make topping off the pond SO MUCH easier. Fingers crossed…

    Please enter me in the giveaway.

    BTW, the lower water pressure/flow can actually be viewed as a feature in areas where water conservation is a concern. I’m guessing a claim about less water being needed when it is dechlorinated can also be made (but I’m not sure on that).

    Any information on the filter’s effect on fluorine?

  12. Mary C. Says:

    Coolio, enter me in! Since I’m trying to grow more and more food, and also eliminate non-natural stuff to the parent’ flower garden this would be a very useful tool! Thanks for offering it!

  13. Jason Says:

    One of these would come in handy when my rain barrels are depleted.

  14. Ragnar Says:

    Ok, this one doesn’t read continental entries only, I’m so in!

  15. Matthew Says:

    For those unable to collect rainwater for their gardening needs, this sounds like the next best thing! And very convenient, too.

  16. Gavin Says:

    This would be great because my drip irrigation system is connected directly to the water supply. If I could add this inline to the system, that provide even better water to my garden.
    Thanks for the tip.

  17. Dan Says:

    Really interesting…
    The EC change sounds really good for hydroponic systems…

  18. Urban Says:

    Looks cool and hopefully I can afford this filter pretty soon 🙂 It would be a great addition to my backyard garden and greenhouse. When dealing with lots of water for hydroponics, water quality becomes a maintenance nightmare if you dont have a good system in place. I was going to invest in a small RO system, but I think I might give this a try first.

    Enter me please for the giveaway. thanks for the info!

    I have a question:
    (sorry for my bad english)

    Can you test the purified water with some kind of cheap aquarium test kit?
    They give a wide range of measurements from chlorine to some basic salts.
    I’m pretty curious about the EC gap, it will be nice to understand what salts are removed from the water.
    I’m interested in hydroponics too.
    Reverse osmosis kits are expensive and hard to maintain, this filter seems promising.
    It will be nice to know if it make the water soft, working on KH or GH.
    This will be useful to balance the nutrients too.

    This sounds great. They make these for showers, too!

    Thanks for the offer. …Harriet
