Auto Pot AirDome Kit

The Auto Pot AirDome Kit is a complete add-on accessory for Auto Pot gravity-fed growing systems. It introduces passive aeration directly at the root zone by suspending an air diffuser dome beneath the growing medium inside the pot or module. The kit ships with every component needed for installation — AirDome body, tubing, connectors, bubble pipe pieces, and printed instructions — so no separate parts are required to get started.

Why Choose the Auto Pot AirDome Kit

The AirDome is designed specifically for Auto Pot’s gravity-fed, pump-free growing systems. Most passive hydroponic systems deliver water and nutrients to the root zone but provide limited oxygen at the roots themselves. The AirDome addresses that limitation by introducing continuous air bubbles directly beneath the growing medium through a low-profile dome positioned at the bottom of the pot.

• Complete kit: Includes the AirDome body, 1/4″ cross connector, 1/4″ straight connector, four pieces of blue bubble pipe, 3.2 ft of airdome tubing, and full installation instructions. Every component is present — nothing additional to source.
• Designed for Auto Pot systems: The AirDome body and connectors are sized and shaped to fit Auto Pot trays and modules directly. This is not a generic diffuser adapted to fit; it is a first-party accessory built to specification.
• Root-zone aeration without additional pumping infrastructure: When connected to a compatible air pump, the AirDome provides a steady supply of dissolved oxygen at the root zone, which supports healthy aerobic root development in a passive system.
• Low component count: The kit uses simple push-fit connectors and flexible tubing. There are no electronic components, no moving parts inside the dome itself, and no maintenance-intensive fittings.
• Instructions included: Full printed instructions ship with the kit. Growers new to AirDome installation do not need to locate separate documentation.

Best Uses for the Auto Pot AirDome Kit

The AirDome Kit is an accessory within the Auto Pot ecosystem. Its utility is specific to passive, gravity-fed growing setups. The following are the primary use cases growers should consider when deciding whether to add the AirDome to their system.

• Auto Pot single-pot and multi-pot systems: The AirDome fits inside Auto Pot trays — including the 1Pot, 2Pot, and XL Pot configurations — where it sits under the growing medium and connects through the tray to an external air pump via the included tubing.
• Coco coir and other inert media: AirDome aeration is particularly beneficial in dense substrates such as coco coir or fine perlite blends, where oxygen diffusion from the surface is slower and root oxygen availability may be limited as the canopy develops.
• High-density or high-transpiration crops: Plants with vigorous root systems (heavy-feeding vegetables, large-fruiting crops) benefit from supplemental root-zone oxygen, especially during the peak of the growing cycle when the medium is densely colonised by roots.
• Transitioning from recirculating to passive systems: Growers moving from active DWC or NFT systems to Auto Pot gravity-fed systems often want to preserve the oxygenation benefits of active systems. The AirDome provides a low-maintenance way to do that without reintroducing active pumping of the nutrient solution itself.
• Existing Auto Pot installations where aeration was not originally fitted: The kit is a retrofit option for growers who set up Auto Pot systems without the AirDome and wish to add root-zone aeration later in the same trays.

Compatibility

The Auto Pot AirDome Kit is designed for use with Auto Pot gravity-fed growing systems. The AirDome body, tubing, and connectors are sized to fit Auto Pot trays and module assemblies. The 1/4″ connectors are standard push-fit fittings compatible with 1/4″ tubing commonly used in Auto Pot installations.

Connecting the AirDome to your grow requires a separate air pump. A multi-outlet air pump such as the Active Aqua 1–8 outlet air pump is suitable for running multiple AirDomes from a single unit in a multi-pot setup. The 3.2 ft length of included tubing accommodates typical tray-to-pump routing distances in bench or floor-level Auto Pot configurations. If your pump is located further from the tray, additional tubing of the same diameter can be used to extend the run.

The AirDome is not intended for use with recirculating or drip-feed hydroponic systems, NFT channels, or systems that do not use Auto Pot-style trays. It is also not compatible with soil-based growing, where the medium would obstruct air diffusion from the dome surface.

For growers monitoring their nutrient solution EC as part of a precise feeding program in the Auto Pot system, compatible EC monitoring equipment is available separately, including replacement EC electrodes for digital meters.
