Bloom Brothers GGWR09 Hydro Halo Water Ring 9-Inch

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!

I bought 2 of these to water my 5 gallon potted plants. They are decent construction, plenty of water holes to evenly distribute waterflow and just very simple, yet brilliant watering devices. No problems whatsoever with these. They have allowed me to setup my irrigation on auto timers so this is now a thoughtless process to water as often as I need.UPDATE: Several months later these are still operating just like they were on day one. I always use distilled water in my basin to push water to these, however I'm typically running nutrients at around 1400PPM through these and I don't have any clogs or salt buildup on the water rings.

Works great

Funcional, pero se requiere una masita grande

Honestly every single one leaks.

It was very effective and worthwhile. It allows me to water plants remotely with the use of an Orbit watering hose timer and 4-way Manifold

It waters my plants perfectly. I did not use the legs but placed the rings directly on top of the soil. I did drill some larger holes into the rings which allows the water to pass better. For what I’m using them for they are working better than I expected. I recommend these “halos”

This tree ring watering gadget is a good concept, but, very poorly designed. The male connector molded into the ring is a bizarre size and definitely will not accept any available drip system 'main line' size. The output holes on the ring dump mass quantities of water (probably should have half the number of holes). I bought two: gerry-rigged one and returned the other. A definite Don't Buy!!
