£0.35

The RootMASS 3.8L Fabric Pot is a compact breathable plant container designed to promote natural air pruning, excellent drainage and improved root-zone aeration. Made from porous fabric rather than rigid plastic, it encourages roots to branch throughout the growing medium instead of continuously circling around the inside of the pot.

The 3.8 litre capacity makes this one of the smaller pots in the RootMASS range and a useful choice for young plants, herbs and intermediate-stage growing before plants are moved into a larger final container.

RootMASS fabric pots are flexible, lightweight and reusable. Their breathable construction works with soil, compost, coco-based substrates and other suitable growing media, making them a versatile alternative to conventional plastic pots.

Why choose the RootMASS 3.8L Fabric Pot?

  • 3.8 litre capacity - a useful compact size for young plants and intermediate-stage growing.
  • Breathable fabric construction - allows greater air exchange around the perimeter of the root zone.
  • Encourages natural air pruning - helps reduce the root circling commonly associated with rigid plastic pots.
  • Supports fibrous root development - air pruning encourages roots to branch further back within the growing medium.
  • Excellent drainage - porous fabric allows excess irrigation water to pass through the container.
  • Improved root-zone aeration - useful where growers want greater oxygen availability around the substrate.
  • Flexible and lightweight - easy to handle, transport and store when empty.
  • Reusable - can be cleaned, dried and reused when maintained appropriately.
  • Versatile substrate compatibility - suitable for soil, compost, coco-based and other appropriate growing media.
  • Indoor or outdoor use - suitable for a wide range of horticultural applications.

Natural root air pruning

When roots reach the solid wall of a conventional plastic pot, they can begin following the shape of the container. Over time this can produce long roots circling around the perimeter of the root ball.

A RootMASS fabric pot works differently. The breathable wall exposes the outside of the growing medium to air. When an actively growing root tip reaches this aerated boundary, extension at the tip is naturally restricted.

This encourages further lateral root development within the growing medium, helping create a more highly branched and fibrous root structure.

Compact 3.8L size for young plants

At 3.8 litres, this RootMASS pot provides a useful step between small propagation containers and larger finishing pots. It gives developing plants additional root space without immediately placing them into an unnecessarily large volume of growing medium.

It can be particularly useful for young plants, herbs, smaller ornamental plants and crops being grown through a staged potting-on system.

Excellent drainage & root-zone aeration

Rather than depending solely on drainage holes in the base, a fabric pot provides a large porous surface through which excess moisture can move. This promotes free drainage while also allowing air exchange around the growing medium.

Fabric pots can consequently dry differently from rigid plastic containers. Check the actual moisture content of the growing medium and adjust irrigation according to plant size, environmental conditions and the substrate being used.

Suitable for soil, compost & coco

The RootMASS 3.8L Fabric Pot can be used with a wide variety of suitable growing media, including conventional compost, soil-based mixes and coco-based substrates.

When filling, distribute the substrate evenly without excessive compaction. Maintaining good pore space within the growing medium complements the aeration and drainage characteristics of the fabric container.

Flexible, reusable & easy to store

Fabric pots have a major practical advantage when large numbers of empty containers need to be stored. Instead of occupying the same volume whether full or empty, they can be folded down for compact storage and transportation.

After use, remove old growing medium and root material, clean the pot appropriately and allow it to dry thoroughly before storing or reusing it.

RootMASS 3.8L Fabric Pot FAQs

What capacity is this RootMASS fabric pot?

This model has a nominal capacity of 3.8 litres.

What are the dimensions of the RootMASS 3.8L pot?

Published dimensions for the 3.8L round RootMASS fabric pot are approximately 15cm x 19cm.

What is air pruning?

Air pruning occurs when actively growing root tips reach the breathable edge of the container. This naturally restricts extension at the tip and encourages further lateral root development within the growing medium.

Why use a 3.8L fabric pot instead of a plastic pot?

The breathable fabric provides greater air exchange and drainage around the root zone while helping reduce the continuous root circling that can occur against a solid plastic pot wall.

Is 3.8L suitable for young plants?

Yes. Its compact capacity makes it particularly useful for young plants and intermediate-stage growing before potting on into a larger container where required.

Can I use coco in this RootMASS pot?

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

Do I need to add drainage holes?

No. The fabric itself is porous and allows excess irrigation water to drain through the container. The pot should still be positioned where run-off can drain or be collected appropriately.

Can RootMASS fabric pots be reused?

Yes. They are reusable. Remove old substrate and roots after use, clean appropriately and allow the pot to dry thoroughly before storing or reusing it.

Can the 3.8L fabric pot be used outdoors?

Yes. It is suitable for both indoor and outdoor horticultural use. Irrigation requirements should be adjusted for temperature, wind, rainfall, plant size and growing medium.

Are fabric pots easy to store?

Yes. Their flexible construction means they can be folded down when empty, requiring considerably less storage space than equivalent rigid pots.
