AutoPot - Hydrotray Single 12" Module – Large-Volume Modular Growing Unit

AutoPot - Hydrotray Single 12" Module – Large-Volume Modular Growing Unit

Engineered specifically for heavy-yielding, large-stature plant varieties, the AutoPot Hydrotray Single 12" Module provides the ultimate foundation for specimen cultivation. 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.

Best For: Large specimen plants, mother plant maintenance, deep-canopy indoor grow rooms, wide-spaced greenhouse crop rows, and scaling up existing AutoPot watering systems.

Key Features

• Designed for Large-Stature Crops: 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.
• Power-Free Gravity Automation: Operates entirely via gravitational fluid pressure from your central supply tank. The absence of electrical wires or moving pump components ensures 100% silent operation and fail-safe irrigation during power outages.
• Demand-Driven Smart Valve Control: Includes a premium Smart Valve that continuously monitors moisture levels at the base. It automatically floods the tray to a set depth, then seals tightly until the root zone has entirely consumed the solution, maximizing root zone oxygenation.
• Flexible, Wide-Space Layouts: The single-pot module design allows you to position large plants further apart as their canopy expands, ensuring maximum light penetration and optimal airflow through heavy foliage.
• Marix Root Control Barrier: Supplied with a custom-cut Marix root control mat that sits perfectly inside the base of the 12" container. This specialized mat stops aggressive root strands from creeping into the valve chamber and disrupting the mechanical float.
• Dedicated 4mm Isolation Tap: Includes a heavy-duty 4mm inline tap, giving you the power to isolate this specific module for flushing, cleaning, or individual plant maintenance without disrupting the rest of your cultivation line.

System Integration & Substrate Management Tips

• Optimizing Substrate Aeration: Because this single module feeds from the bottom up via capillary action, choose an open, highly porous medium to fill the large 12" pot. 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. Avoid unamended, dense potting soils that risk waterlogging.
• Splicing into Your Setup: Cut your existing supply line at the desired position, insert a 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 fast line isolation.
• The Critical Top-Watering Phase: When first transplanting large clones, seedlings, or staging up from an **Eazy Block**, hand-feed the plant from the top while keeping the 12" pot outside of the module for the first 7–10 days. 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.
• Level Flooring for Valve Precision: 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.

Ideal For (Uses)

• Long-Term Mother Plants: Keeping vital mother plants healthy, vibrant, and well-fed for months or years in a self-regulating, non-compacting environment.
• Heavy Fruiting Specimen Crops: Maximizing flower and fruit yields for massive individual producers like giant tomatoes, industrial chillies, eggplants, and large ornamental shrubs.
• Bespoke Commercial Mapping: Allowing large-scale facilities to map out wide-spaced rows, perfectly accommodating oversized plant canopies while utilizing a centralized gravity feed reservoir.
