Bloom Brothers Hydro Halo Watering Rings
Bloom Brothers makes the Hydro Halo -- a circular drip ring designed for even water and nutrient distribution around the full perimeter of a container or growing site. The halo mounts on three adjustable legs that position the ring above the growing medium surface, with a single 1/2 inch barbed inlet connecting to standard drip tubing. Multiple small outlet holes around the ring distribute irrigation water evenly in a 360-degree pattern rather than concentrating moisture at a single drip point, promoting more uniform root zone saturation and reducing dry spots at container edges.
Size Range and Compatibility
Bloom Brothers Hydro Halo rings are available in 6-inch, 9-inch, and 12-inch diameters. The 6-inch ring is sized for 1 to 3 gallon containers. The 9-inch fits 5 to 7 gallon containers. The 12-inch is suited for 7 to 15 gallon containers and larger rockwool slab or coco bag applications. All sizes use a 1/2 inch barbed connection compatible with standard 1/2 inch poly drip irrigation tubing. The three-leg stand design allows height adjustment to position the ring appropriately above different media heights.
Applications in Container Drip Systems
Hydro Halo rings work with any gravity-fed or pressure-driven drip irrigation system using 1/2 inch supply tubing. They are particularly effective in rockwool slab, coco bag, and large container drip programs where single-point drip stakes create channeling and uneven slab saturation. Browse all irrigation supplies or see Netafim drip components for compatible tubing and fittings. Fast shipping.
Hydro Halo FAQ
What size Hydro Halo do I need for my containers?
Match the Hydro Halo diameter to your container size. The 6-inch ring fits 1 to 3 gallon containers where the ring diameter is slightly smaller than the container opening, allowing even perimeter distribution in a small footprint. The 9-inch ring is suited to 5 to 7 gallon containers. The 12-inch ring works with 7 to 15 gallon containers and larger rockwool slabs or coco grow bags. For grow bags and slabs that are not round, select a ring diameter that fits within the footprint without the legs resting outside the media -- the distribution pattern should cover the full growing area.
How do you connect a Hydro Halo to a drip irrigation system?
The Hydro Halo uses a 1/2 inch barbed inlet that connects directly to standard 1/2 inch poly drip tubing. Insert the barbed fitting into the end of your 1/2 inch supply line -- no clamp required for low-pressure drip systems. Position the three-leg stand so the ring sits 1-2 inches above the growing medium surface, ensuring even distribution into the media rather than spraying above it. For multi-site drip systems, run 1/2 inch mainline to each container and connect the Halo at each site. Use a flow-controlled emitter upstream if you need to manage per-site flow rates in a multi-zone system.
Can Hydro Halos be used with Netafim or FloraFlex drip systems?
Yes. The Hydro Halo 1/2 inch barb is compatible with standard 1/2 inch poly drip tubing used in Netafim, FloraFlex, and other drip irrigation systems. The Halo functions as the terminal distribution device at each site, replacing a single drip stake with 360-degree perimeter distribution. In Netafim systems using 17mm Bright White PE mainline, connect a 1/2 inch poly branch line from a manifold or barbed tee fitting, then connect the Halo at the container. For FloraFlex systems with 1/2 inch poly distribution tubing, the connection is direct and straightforward.
