Ambius sub-irrigation solution for indoor plants

Ambius sub-irrigation is our best-practice watering system for commercial indoor plants, designed to maintain lush, healthy greenery with minimal intervention. Unlike traditional top-watering, sub-irrigation delivers water directly into a sealed reservoir beneath the grow pot. The plant then draws up precisely the amount of water it needs through capillary action, promoting stronger root systems and preventing overwatering.

This advanced technique delivers less intrusive maintenance, and consistent plant health across your workplace. It provides a sustainable foundation for thriving commercial environments and is available across Ambius containers, bespoke designs, and client-owned planters.

What is Sub-Irrigation?

Sub-irrigation is a precise, eco-friendly watering method where water is introduced beneath the plant's grow pot and absorbed upward via a specialised wick or sub-irrigation insert.

  • Prevents Overwatering: Delivers targeted water directly to roots, reducing root rot and soil compaction.

  • Conserves Water: Sealed reservoirs minimize evaporation and eliminate runoff or water damage to office floors.

  • Encourages Stronger Roots: Consistent upward moisture flow stimulates deeper, healthier root growth.

  • Extends servicing cycles: Larger water capacity extends watering intervals, ensuring less intrusive servicing for your workplace.

Smarter Design. Stronger Sustainability.
Ambius sub-irrigation is now available as a flat pack solution. What this means: it reduces storage and transport, it is cost effective, while supercharging your sustainability goals.

Subirrigation

How it works?

  • The water is poured into the container, the wick at the bottom of the grow pot takes the water up to the roots of the plant by osmosis. 

  • Osmosis is the movement of water from an area of high concentration which is how the plant roots draw water to soil. 

  • The wick acts as a prosthetic root with access to a reservoir that is able to take water up on it’s own terms.

Why subirrigation

Why sub-irrigation?

  • Better for the health of the plant, extends plant life 

  • Water reservoir holds enough water between servicing, providing peace of mind especially during warmer conditions

  • Using cone liners provides a sealed, leak proof solution

  • Reduced shock to plants, as water is able to reach room temperature in reservoir

  • Reduced plant pests and disease

  • Enables the plants to effectively remove VOC’s thus improving Indoor Air Quality

  • Longevity of topping condition (top watering stains)
