Product description

More effective irrigation of all types of pots/ containers in all growing mediums.; Drip emitters and stakes only provide a single point of irrigation making it hard for water/ nutrient solution to evenly saturate a container. The water ring has 54 perfectly positioned pores to evenly irrigate containers eliminating dry pockets of growing medium. Kit contains 3 removable stakes to keep water rings in place around each plant. The water ring can also be used without the stakes if desired. The water ring has a 1-Inch gap on one end to allow it to be placed around large plants without damaging the stalks. Can be used indoors or out in soil or hydroponics. Durable construction allows for years of use. Can be easily cleaned between growing cycles. Create your own flexible irrigation kits easily and cheaply with any-Inch I.D. tubing and-Inch fittings (not included). Please note that adding-Inch ball valves may be necessary to create an even flow to all water rings in large installations.

    They quite obviously figure they have the market cornered. I would have made my own, but I gave in the the time it would take me to make them myself out of metal. I very recently purchased some copies for half the price of these. Probably costs them 12 cents to make "overseas". Good deal for them if they can get suckers like me to cough up the cash. On a more positive note, they work very well.

    Aunque el anuncio del producto hace referencia a que el kit se compone de 3 unidades, solamente trae 1 unidad, lo he devuelto ya que lo considero publicidad engañosa.

    Works wonders for those who want an automatic feeding system, and an all round equal watering, works perfectly, plants are thriving and the halo hasn't shown any signs of degrading or any limescale/salt build up as yet.

    5.0 out of 5 stars YOU NEED 0.520" ID VINYL POND TUBING TO CONNECT THESE
    Reviewed in the United States on February 25, 2022
    Verified Purchase
    HELP ME HELP YOU!!! I don't know why this isn't listed in the product description, but the connector on the ring requires 0.520" inner diameter tubing, which is sold as "1/2" vinyl pond tubing."

    There are (at least) three different sizes of tubing that are all referred to as "half-inch": 0.520", 0.60", & 0.62" ID. The standard "half-inch" black poly irrigation tubing (e.g. Rain bird) that you'll find in the irrigation aisle at a home improvement store is 0.60" ID/0.70" OD, which will be very loose & will not work. You need 0.520" ID vinyl "pond tubing" to connect to the nipple, which I found in the outdoor/plants section.

    Search for "DIY Automatic Watering System for Indoor Cannabis" at Cocoforcannabis to find a write up of Hydro Halos and how to set these up. I already had 0.60" poly irrigation tubing in my setup, and I learned that you can connect 0.60" poly tubing to the 0.520" vinyl tubing that the Hydro Halo uses with Rain Bird brown-colored "1/2 in. Barbed Couplings". These couplings are really meant for the 0.60" poly tubing, but if you soak the 0.520" vinyl tubing in boiling water to soften them up, you can, with some effort, fit them on the coupler and thereby connect the two different sizes of tubing.

    While I've only used them for a few days, the Hydro Halos are working great so far. Just be sure to buy ball valves for each ring you are connecting so meter/equalize the flow of water. 13 mm/0.520" ball valves are the easiest to use, but you can also use 16 mm ball valves if you soak the tubing in boiling water to soften it up, as referenced above.

    I don't know why this isn't more clearly listed in the product description. I drove myself nuts for two hours trying to figure out why my "half-inch tubing" didn't work. Hope this helps someone out!
