4 Pot XXL Grassroots System

These premium Grassroots Living Soil Fabric Pots offer a high-performance alternative to traditional plastic or ceramic containers and pair exceptionally well with Auto Pot sub-irrigation systems.

Constructed from durable, American-made geotextile fabric with two sturdy handles, these pots are designed to create a healthier root environment by increasing airflow through the container walls.

This promotes natural air pruning, prevents root circling, and helps regulate soil temperature, allowing plants to develop stronger and more efficient root systems.

Each pot features a specialized internal liner that helps balance moisture retention with proper drying cycles.

The waterproof liner extends 8 inches down from the pot rim, including the interior brown strip, helping maintain consistent moisture levels in the upper portion of the soil profile while still allowing the lower root zone to wick water effectively from the Auto Pot tray.

A bottom aeration strip keeps the lower portion of the pot breathable, encouraging natural top-down drying and creating an ideal environment for beneficial microbes commonly found in living soil and biologically active substrates.

Standing 18 inches tall, these pots provide generous root volume and excellent vertical soil structure, making them particularly well suited for living soil growers and those running organic or microbially active growing methods.

By combining the natural advantages of breathable fabric containers with a carefully designed moisture control liner, Grassroots Living Soil pots deliver a balanced root environment where plants receive consistent moisture, excellent oxygen availability, and the soil biology needed for vigorous growth.

Cultivating big plants, whether one or many, requires time and technique.

XXL brings ultra-low maintenance, plant-controlled AQUAvalve5 irrigation into the realm of giant growing – giving you the opportunity and head space to hone your horticultural skills.

As with all Auto Pot Watering Systems, XXL operates power-free, without the need for running water, and without pumps or computers to maintain.

Immense savings in time, money, and ecology are obvious merits.

Such virtues are equaled only by the responsiveness with which plants are fed and watered.

The AQUAvalve5s that regulate every module respond exactly to each individual plant’s needs, supplying water and nutrient solution only as and when required, without recirculation or a drop of waste.

The 1 Pot XXL System is easily extended so many pots can be linked to a single reservoir.

The pots & trays can be easily moved at will, if the plants grow too large they can be spaced further apart with ease.

Once set up and a reservoir is filled with water & mineral liquid feed this extremely versatile system will completely take care of all your plants needs.

All you need to do is remember to fill up your reservoir from time to time.

If you want to add extra oxygen to your root zone, consider adding Air Domes.
