The Chapin HydroFeed fertilizer injector is a patent-pending design filled with features for use with sprinklers and direct hose spray applications. Great way to conserve water and still have a lush, green, well-fed landscape or garden. Different than a hose-end sprayer. HydroFeed works differently than a standard hose-end sprayer. A standard hose-end sprayer pulls the chemical up and out, emptying the tank. HydroFeed adds water back into the tank as your chemical is being pulled out. Because your chemical has a higher density than water, it sits on the bottom of the tank. Our outlet tube reaches the bottom of the tank so when clean water is being added to the tank, it stays on top of your chemical mix. You don’t have to worry about your chemical being diluted as it’s being fed through the outlet tube. This is why the tank turns clear after your chemical runs out.

    I received the Chapin Hydro Feed as a free sample from TryIt. The 1-gallon fertilizer injector with variable rate adjustment is an auto-mix system to apply fertilizer easily with professional results. Can be used as a drip irrigation system, with sprinkler systems, with soaker hoses, or with standard garden hose nozzles.

    I got this In-Line Fertilizing Injection System to use on my lawn and vegetable gardens. It is designed to be used via, drip irrigation, sprinkler, soaker hose and direct hose. It is a 1 gallon tank and you can mix water with liquid and granules. It was very easy to put together and all the pieces come included. I use it with my soaker hose on my vegetable garden and I hook it to my sprinkler system when fertilizing my lawn. This is so handy and saves me so much time. I highly recommend this product to anyone whom gardens and anyone whom loves having the perfect yard. Great product.

    After the cold front came through my grass was dead. I needed an easy way to fertilize my yard. I hooked this up into my sprinkler system was amazed at the results. I am not mechanically inclined so I was concerned the set up would be difficult. I was wrong; the set up was easy. Great job.

    I purchased the Chapin 4710 one-gallon in-line fertilizing injection system for sprinkler and hose about 2 months ago. It’s a great way to conserve water. Their outlet tube
    reaches the bottom of the tank so when
    clean water is added it stays on the top of your chemicals. Great product!

    We put in a garden last year and it was such a pain making sure that our plants were fertilized with the right amount throughout the seasons. Having a system like this is going to work wonders for us this year. Installing it and setting it up for our garden was fairly simple.
