Super Sprouter AirMax Tray Insert - For Super Sprouter Dome and Tray Kits

Super Sprouter AirMax Insert — Mesh Drainage and Root-Zone Aeration

The Super Sprouter AirMax Tray Insert is a mesh tray insert engineered to deliver outstanding drainage and aeration for clones propagated in Grodan Stonewool A-OK Starter Plugs. The open mesh design lets air circulate freely around root zones while draining instantly, creating a strong environment for vigorous rooting. It is designed to fit within Super Sprouter dome and tray propagation kits.

Growers moving up from solid-wall insert trays typically notice faster, more even root establishment, since standing water and anaerobic pockets at the base of each plug are largely eliminated by the open mesh floor.

Key Features & Benefits

• Open Mesh Construction: Maximizes air circulation around starter plugs, promoting passive air pruning and preventing anaerobic conditions at the root zone.
• Outstanding Drainage: The mesh base drains instantly and completely, eliminating standing water beneath starter plugs and reducing the risk of root disease from overwatering.
• Sized for Grodan Stonewool A-OK Starter Plugs: Cell spacing and mesh dimensions are optimized to hold Grodan A-OK stonewool plugs securely while exposing their base and sides to open air.
• Fits Super Sprouter Dome and Tray Kits: Designed as an accessory insert for Super Sprouter propagation tray systems, matching the standard tray footprint.
• Promotes Root Development: Air exposure at the plug base air-prunes roots, stimulating lateral branching for a denser root structure that establishes faster after transplanting.

Who Should Use This

Propagators using Super Sprouter dome and tray kits with Grodan Stonewool A-OK Starter Plugs who want to maximize aeration, drainage, and root quality during cloning and early propagation. Well suited to high-performance propagation setups where root quality is a priority.

Compatibility

Designed for use with Super Sprouter propagation tray and dome kits, and optimized for Grodan Stonewool A-OK Starter Plugs. Pairs with Super Sprouter standard and Quad Thick propagation trays and Super Sprouter humidity domes.

Frequently Asked Questions

How is the AirMax insert different from a standard solid-wall insert tray?

The AirMax insert uses open mesh construction instead of solid cell walls. Air circulates freely under and around each starter plug, providing passive air pruning and instant, complete drainage that solid-wall inserts cannot match.

What starter plugs work with the AirMax insert?

The AirMax insert is sized for Grodan Stonewool A-OK Starter Plugs. It may also suit other rigid stonewool or plug media that hold their shape without needing a closed cell wall for support.

What is air pruning and why does it help my cuttings?

Air pruning happens when root tips are exposed to air and naturally stop elongating downward, which triggers lateral root branching instead. The result is a denser, more fibrous root ball that establishes faster once transplanted.

When should I move cuttings out of the AirMax insert?

Transplant once roots are visibly developed at the plug base and the cutting shows active new growth above the media. Most growers move cuttings within one to two weeks of a healthy root strike, though timing varies with propagation conditions.
