Whether you are expanding an active setup or building a completely customized gravity-fed network, this standalone module delivers commercial-grade reliability without requiring electricity, water pumps, or noisy digital timers. Featuring a spacious 12\" individual pot profile, it grants large root networks the volume they need to expand freely. Water delivery is managed entirely by the pressure-sensitive Smart Valve (AQUAvalve), which automatically responds to the plant's actual water consumption—ensuring a perfect wet-and-dry irrigation cycle that drives rapid growth while eliminating over-watering and nutrient runoff waste.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Large specimen plants, mother plant maintenance, deep-canopy indoor grow rooms, wide-spaced greenhouse crop rows, and scaling up existing AutoPot watering systems.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesigned for Large-Stature Crops:\u003c\/strong\u003e The generous 12\" pot capacity provides an expanded substrate volume, allowing massive, heavy-fruiting, or long-term varieties to develop an extensive root architecture without becoming root-bound.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower-Free Gravity Automation:\u003c\/strong\u003e Operates entirely via gravitational fluid pressure from your central supply tank.

A 50\/50 blend of premium **Coco Coir** and **Horticultural Perlite**, or a 50\/50 mix of organic soil and **Hydro Clay LECA** pebbles works flawlessly.

Once a strong network of white roots has successfully reached the base of the container, drop it into the Hydrotray and activate the gravity feed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLevel Flooring for Valve Precision:\u003c\/strong\u003e Ensure the Hydrotray base sits completely level on your greenhouse floor or grow bench. If the tray is tilted or angled, the water level across the Smart Valve seat will be uneven, which can cause the float mechanism to stick open or fail to shut off properly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIdeal For (Uses)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong-Term Mother Plants:\u003c\/strong\u003e Keeping vital mother plants healthy, vibrant, and well-fed for months or years in a self-regulating, non-compacting environment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy Fruiting Specimen Crops:\u003c\/strong\u003e Maximizing flower and fruit yields for massive individual producers like giant tomatoes, industrial chillies, eggplants, and large ornamental shrubs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBespoke Commercial Mapping:\u003c\/strong\u003e Allowing large-scale facilities to map out wide-spaced rows, perfectly accommodating oversized plant canopies while utilizing a centralized gravity feed reservoir.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e","brand":"Holland Forge","offers":[{"title":"Default Title","offer_id":48423987937380,"sku":"4240","price":56.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/ChatGPTImageMay16_2026_10_10_26PM.png?v=1778940638","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/autopot-hydrotray-single-12-module-large-volume-modular-growing-unit","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
