The RootMASS Square Fabric Pot 17L is a breathable fabric growing container measuring W27cm x D27cm x H25cm, designed to encourage a healthy, fibrous root system through natural air pruning. Its square footprint makes efficient use of growing space, while integrated handles make the pot easier to position and move when required.

Unlike conventional solid-sided plastic pots, the breathable fabric construction allows air to reach the outer area of the growing medium. When actively growing roots reach the edge of the container, exposure to air naturally restricts the root tip. The plant responds by producing additional lateral and feeder roots rather than allowing the roots to continually circle around the inside of the pot.

This air-pruning effect encourages a more branched root structure throughout the growing medium. Combined with excellent drainage and increased root-zone aeration, the RootMASS 17L offers a practical alternative to conventional rigid plant pots for a wide range of container-growing applications.

Why choose the RootMASS 17L Fabric Pot?

  • 17 litre capacity - a versatile medium-sized container for a wide range of plants and growing applications.
  • W27 x D27 x H25cm - compact square dimensions make efficient use of available growing space.
  • Encourages natural air pruning - breathable fabric exposes root tips to air as they reach the edge of the container.
  • Helps reduce root circling - encourages roots to branch within the growing medium rather than continually following a solid pot wall.
  • Promotes a fibrous root structure - air pruning encourages the formation of additional lateral and feeder roots.
  • Breathable root zone - porous fabric allows increased air exchange around the growing medium.
  • Free-draining design - excess irrigation can drain through the fabric rather than relying solely on drainage holes in the base.
  • Space-efficient square shape - square pots can be positioned closely together with less unused space between containers.
  • Integrated handles - useful for positioning and moving the pot when required.
  • Compact when empty - flexible fabric construction allows the pot to be flattened for convenient storage.

How does a RootMASS fabric pot air prune roots?

Roots growing inside a conventional smooth-sided plastic pot eventually reach the container wall. Because the solid wall prevents further outward growth, roots can begin following the shape of the container, potentially creating a mass of circling roots around the outside of the growing medium.

RootMASS fabric pots work differently. Their breathable walls allow air to reach the outer edge of the root zone. When an actively growing root tip reaches this air-rich area, growth at the tip is naturally restricted.

The plant responds by developing additional branches further back along the root. As the process continues throughout the container, it encourages a network of finer roots rather than a small number of long roots circling the pot wall.

Square design for efficient growing spaces

Measuring 27cm wide x 27cm deep, the RootMASS 17L has a compact square footprint. This makes it particularly useful when several plants are being grown alongside one another.

Square pots can be arranged closely together without the larger gaps naturally created between round containers. This can help make better use of available floor, bench or growing tray space.

At 25cm high, the 17 litre format provides useful growing-medium depth while retaining a manageable overall size.

Improved drainage & root-zone aeration

The porous construction of a fabric pot allows both air and moisture to move through the container walls. This provides a different root-zone environment from a conventional solid plastic pot.

Excess irrigation can drain through the fabric, while increased air exchange around the sides of the growing medium helps maintain an aerated root environment.

Because fabric pots breathe and drain freely, watering requirements can differ from those of rigid containers. Moisture levels should therefore be checked regularly and irrigation adjusted according to the plant, growing medium and environmental conditions.

Suitable for a wide range of growing media

The RootMASS Square Fabric Pot can be used with suitable container composts, soil mixes, coco-based substrates and other compatible growing media.

The 17 litre size provides a useful balance between root volume and overall footprint, making it suitable for many ornamental, flowering, fruiting and productive container-grown plants.

Always select the growing medium, irrigation and feeding programme according to the requirements of the particular plant being grown.

Watering a 17L fabric pot

Fabric pots can dry differently from rigid plastic containers because moisture can leave through the breathable sides as well as the surface of the growing medium.

Rather than watering to a fixed timetable, check the moisture level within the growing medium and irrigate according to the plant's requirements. Temperature, airflow, plant size, growing medium and stage of growth can all affect how quickly the container dries.

A suitable tray or saucer can be positioned beneath the RootMASS pot where irrigation runoff needs to be collected or contained.

Integrated handles for easier positioning

The RootMASS 17L incorporates handles into the fabric pot design, providing convenient handholds when positioning the container.

As with any planted container, the overall weight will depend heavily on the growing medium, moisture content and plant. Take appropriate care when moving a filled pot and support the container as necessary.

RootMASS Square Fabric Pot 17L FAQs

What size is the RootMASS 17L Square Fabric Pot?

The pot measures 27cm wide x 27cm deep x 25cm high and has a stated capacity of 17 litres.

What does air pruning do to plant roots?

When an actively growing root reaches the breathable edge of the fabric pot, exposure to air restricts growth at the root tip. This encourages additional branching further back along the root and helps produce a more fibrous root structure.

Can RootMASS fabric pots help reduce circling roots?

Yes. The breathable fabric encourages air pruning rather than providing the solid wall that can cause roots to continue growing around the perimeter of a conventional pot.

Why choose a square fabric pot instead of a round one?

The square 27 x 27cm footprint allows multiple containers to be positioned closely together, helping make efficient use of available growing space.

Does the RootMASS pot need drainage holes?

The breathable fabric itself is porous, allowing excess irrigation to drain through the container rather than relying solely on conventional holes in the base.

Can I place a RootMASS pot in a saucer or tray?

Yes. A suitable tray or saucer can be used beneath the pot where irrigation runoff needs to be collected.

Can I use coco in the RootMASS 17L?

Yes. RootMASS fabric pots can be used with suitable coco-based growing media as well as appropriate compost and soil-based container mixes.

Do fabric pots need more frequent watering?

The breathable walls can cause the growing medium to dry differently from a rigid plastic pot. Check moisture regularly and adjust irrigation according to the plant, substrate and growing conditions rather than following a fixed schedule.

Can the RootMASS pot be folded for storage?

Yes. When empty, the flexible fabric construction can be flattened, making the pots compact and convenient to store.

What can I grow in a 17L fabric pot?

A 17 litre container is suitable for a wide range of ornamental, flowering, fruiting and productive plants. The appropriate final pot size will depend on the particular plant and the root volume it requires.
