A time-tested, commercial-grade favorite among legacy horticultural managers and high-volume indoor growers, this massive parabolic dome is specifically engineered to orient and fire high-intensity discharge lamps in a vertical downward position. Traditional horizontal reflectors throw intense, focused lines of radiant energy directly below the bulb's arc tube, which can create volatile localized heat signatures and stunted crop spots. By mounting the lamp vertically, the SeaHawk Deep Bowl captures the uniform 360-degree radial light output of your bulb and redirects it down across an expansive geographic radius. This mechanical alignment disperses intense intersecting light rays far and wide, radically minimizing under-hood hot spots while maximizing light penetration into dense lateral branch layers. Spanning a commanding 740mm diameter and built to rugged structural specifications, this heavy-duty fixture features an optimized reflective profile that turns a single HID bulb into a wide-angle dispersion system. Ideal for scaling up extensive commercial facilities, warehouse grow lines, or high-density nursery benches, these premium reflectors are distributed in bulk packaging configurations and are available exclusively in factory carton quantities of 10 or more units.\u003c\/p\u003e\n  \n  \u003chr\u003e\n  \n  \u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Large-scale open room cultivation, uniform wide-angle canopy light mapping, eliminating under-hood thermal hot spots, and bulk multi-bench commercial facility scaling.\u003c\/p\u003e\n\n  \u003ch3\u003eKey Features \u0026amp;

Position your reflectors 65cm to 85cm above the top of your plants. Space multiple fixtures evenly across your room so that the outer edges of their light rings overlap perfectly on your benches, filling in any gaps and driving light down into your plants from multiple angles.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRoot-Zone Hydration and Substrate Coordination:\u003c\/strong\u003e The wide, uniform light footprint delivered by a vertical parabolic reflector maximizes the leaf surface area actively performing photosynthesis across your entire room.

To keep your grow space at the ideal temperature range (24°C to 27°C), mount your main inline extraction fan high up in the ceiling to pull trapped heat out of the room, combined with a grid of oscillating fans below the hoods to keep air moving smoothly over your canopy.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSetting Up Safety Drip Loops for Vertical Socket Leads:\u003c\/strong\u003e Because commercial open rooms and large propagation bays operate at high humidity levels, protecting your electrical lines is paramount. When routing the heavy-duty power lead from your deep bowl's vertical center socket up to your ceiling tracks and back to your remote ballasts, always ensure the cable drops into a loose, shallow U-shape bend right before it enters your line conduits. This forms a natural \"drip loop\"—any ambient room condensation or stray moisture tracking down the wire will pool safely at the bottom of the bend and drip to the floor rather than running directly into active electrical connections.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eIdeal For (Uses)\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLarge Commercial Warehouse Expansions:\u003c\/strong\u003e The ultimate option for commercial facility operators outfitting massive open rooms or warehouse rows who need a durable, wide-angle light hood to maximize coverage per light.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh-Density Shared Nursery Benches:\u003c\/strong\u003e Perfect for propagation rooms and vegetative bays where large groups of plants are packed closely together on wide tables and require uniform light from edge to edge.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFragile Terpene and Essential Oil Protection:\u003c\/strong\u003e An exceptional choice for growers looking to reduce thermal stress on delicate flower tops, using the diffuse parabolic shape to minimize infrared hot spots and protect crop quality.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/section\u003e","brand":"Holland Forge","offers":[{"title":"Default Title","offer_id":48454043402340,"sku":"4025","price":39.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/ChatGPTImageMay23_2026_10_12_00PM.png?v=1779545573","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/seahawk-740mm-deep-bowl-umbrella-reflector-vertical-orientation-high-diffusion-canopy-hood","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
