Whether you are engineering a custom hydroponic floor plan from scratch or expanding an existing AutoPot kit, this standalone module provides a flexible, commercial-grade solution. Driven entirely by gravity, this unit requires no electricity, noisy pumps, or digital timers to function. The module features a dedicated dual-pot tray base managed by a pressure-sensitive Smart Valve (AQUAvalve), which automatically regulates water delivery based on the plants' actual consumption rates. By allowing crops to determine their own feeding schedule, this system maximizes root zone oxygenation and completely eliminates the hassle of over-watering and nutrient runoff waste.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Custom hydroponic system builders, expanding existing 2-Pot or 8-Pot AutoPot kits, stepping up plant counts in indoor tents, and configuring multi-row greenhouse cultivation lines.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeamless Kit Expansion:\u003c\/strong\u003e Engineered to splice directly into your existing gravity-fed network.

A 50\/50 blend of loose **Coco Coir** and **Horticultural Perlite**, or a 50\/50 mix of soil and **Hydro Clay LECA** pebbles ensures a perfectly balanced, aerated root environment. Avoid tight, unamended potting clays or fine peat moss.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlumbing into the Main Line:\u003c\/strong\u003e Cut your existing supply line near your target position, insert a standard multi-way tee or cross fitting, and run a length of flexible tubing to the module's included 4mm isolation tap. Ensure the tap remains easily accessible for quick line isolation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe Critical Rooting Period:\u003c\/strong\u003e When transplanting young clones or seedlings into the 10\" pots, hand-feed them from the top while keeping the pots outside of the module for the first 7–10 days. Once a strong network of white roots has developed and reached the floor of the containers, drop them into the Hydrotray and turn on the gravity supply line.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintaining Valve Reliability:\u003c\/strong\u003e Ensure the Hydrotray base sits completely level on your grow room floor or benching. If the tray is tilted, the water level across the Smart Valve seat will be uneven, which can cause the valve 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\u003eCustom Layout Staging:\u003c\/strong\u003e Allowing commercial facilities and hobbyists to map out bespoke irregular shapes, matching unusual floor plans or expanding angled tent corners perfectly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStaggered Harvest Management:\u003c\/strong\u003e Integrating separate vegetative or flowering plants into an active setup on different dates, utilizing the isolation tap to control watering independently.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Density Crop Production:\u003c\/strong\u003e Maximizing fruit and flower yields for heavy-producing specimen crops like tomatoes, capsicums, chillies, and brassicas.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e","brand":"Holland Forge","offers":[{"title":"Default Title","offer_id":48423981940836,"sku":"4237","price":52.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/ChatGPTImageMay16_2026_09_51_23PM.png?v=1778939499","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/autopot-hydrotray-double-10-module-modular-gravity-fed-expansion-unit","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
