£0.16

The 3L Round Plant Pot is a practical black horticultural grow pot designed for nursery production, greenhouse growing, potting-on and general container cultivation. With an approximately 18.5cm upper rim, 14cm base and 15cm height, it provides a useful 3 litre root volume in a compact, easy-to-handle format.

Three litre pots are one of the most versatile sizes in horticulture, providing a useful intermediate step between small propagation containers and larger finishing pots. They are suitable for a wide range of perennials, herbs, vegetables, ornamentals and young nursery plants.

The tapered round profile makes the pot straightforward to handle and allows empty containers to nest efficiently for storage. A reinforced upper rim provides a practical gripping point when plants need to be moved around a nursery, greenhouse or growing area.

Drainage openings in the base allow excess irrigation water to escape, helping maintain an appropriate balance between moisture and oxygen within the root zone.

Suitable for peat-based and peat-free compost, soil, coco coir and other horticultural growing media, this 3L pot is equally useful for professional growers and home gardeners.

A versatile 3 litre growing volume

A 3L pot provides significantly more root volume than small propagation and early-stage containers while remaining compact enough for efficient plant spacing.

This makes it particularly useful for growing-on established young plants. Moving a plant into a suitably larger container gives developing roots additional growing medium to explore without immediately placing a small root system into an unnecessarily large volume of wet substrate.

For many nursery crops, 3L is also a convenient retail and finishing size. For larger or more vigorous plants, it can instead serve as an intermediate stage before moving into a larger container.

3L Round Pot dimensions

The pot measures approximately 18.5cm across the upper rim, 14cm across the base and 15cm high.

These proportions create a compact horticultural container with useful root volume while maintaining a manageable footprint for greenhouse benches, nursery beds and indoor growing areas.

The tapered sides also allow empty pots to nest inside one another, making storage and handling considerably more efficient.

Suitable growing media

The 3L Round Plant Pot can be used with a broad range of horticultural substrates, including:

  • Peat-based potting compost
  • Peat-free growing media
  • Soil-based potting mixes
  • Coco coir
  • Coco and perlite blends
  • Living soil
  • Other suitable horticultural substrates

Irrigation frequency should always be adjusted to suit the crop and substrate. Free-draining coco behaves very differently from a moisture-retentive compost, even when both are used in the same size container.

What can you grow in a 3L pot?

Three litres is a widely useful container size for growing-on and finishing smaller plants. Typical applications include:

  • Herbaceous perennials
  • Herbs
  • Bedding and patio plants
  • Young shrubs
  • Young climbing plants
  • Chillies and peppers
  • Young tomato plants
  • Strawberries
  • Ornamental plants
  • General nursery stock

Whether 3L is suitable as a final pot depends on the plant species, expected mature size and crop duration. Vigorous plants may eventually need potting-on again.

Drainage & root-zone management

Drainage openings in the base allow excess irrigation water to leave the container instead of remaining trapped around the lower roots.

Effective drainage helps maintain the combination of moisture and air required for healthy root development. It is particularly important when plants are frequently irrigated or grown in controlled greenhouse and indoor environments.

The pot can be used with hand watering, drip irrigation and other suitable nursery irrigation systems.

Avoid watering purely according to a fixed timetable. Plant size, root development, substrate, temperature, humidity and light levels all affect how quickly a 3L pot will dry.

Fits the 18cm Pot Saucer

The 3L Round Plant Pot is compatible with the 18cm Pot Saucer, product code P00103.

The matching saucer measures approximately 18.5cm across the rim, 16.5cm across the base and 3cm high.

A saucer is useful when the pot is used indoors, on greenhouse benches or on protected surfaces where irrigation runoff needs to be contained.

In outdoor or free-draining production areas, a saucer may not be necessary.

Ideal for nursery & greenhouse production

Three litre round pots are particularly useful in nursery production because they provide enough growing-medium volume for established young plants without requiring the space of much larger containers.

The manageable size makes plants easy to move, space, irrigate and prepare for sale, while the black horticultural finish provides a straightforward professional presentation.

The pot is also useful for home growers who want a functional growing container rather than a decorative planter.

Practical & reusable

Pots that remain in good condition can be emptied, cleaned and reused for future crops.

Remove old substrate and root debris before cleaning. Where pots are being transferred between crops, appropriate hygiene procedures can help reduce the risk of carrying pests or plant pathogens into the next planting.

Empty pots can be nested together for compact storage between uses.

3L Round Plant Pot FAQs

What are the dimensions of the 3L Round Pot?

The pot measures approximately 18.5cm across the upper rim, 14cm across the base and 15cm high.

What can I grow in a 3L plant pot?

A 3L pot is suitable for many perennials, herbs, bedding plants, young shrubs, chillies, peppers, strawberries, ornamentals and nursery crops. Larger plants may eventually require potting-on.

Is a 3L pot suitable for chillies and peppers?

Yes. Three litres can be suitable for smaller chilli and pepper plants or as an intermediate growing size. Larger and more vigorous plants may benefit from additional root volume later in the crop.

Can this pot be used for tomatoes?

It is suitable for growing-on young tomato plants, but most mature tomato plants will normally benefit from a substantially larger final container.

Can I use coco coir in the 3L Round Pot?

Yes. Coco and coco-based blends can be used in this pot. Adjust irrigation frequency to suit the free-draining characteristics of the growing medium.

Can I use peat-free compost?

Yes. The pot is suitable for peat-free growing media as well as conventional compost, soil mixes, coco and other appropriate horticultural substrates.

Does the 3L Round Pot have drainage holes?

Yes. Drainage openings in the base allow excess irrigation water to leave the growing medium.

Which saucer fits the 3L Round Pot?

The compatible option is the 18cm Pot Saucer, product code P00103. It measures approximately 18.5cm across the rim, 16.5cm across the base and 3cm high.

Do I need a saucer underneath the pot?

A saucer is useful where runoff needs to be contained, particularly indoors or on protected surfaces. It is not essential where excess water can safely drain away.

Is this pot suitable for nursery production?

Yes. The 3L size is widely useful for growing-on nursery plants because it combines practical root volume with a compact, easy-to-handle container.

Can this pot be used outdoors?

Yes. It can be used outdoors as well as in greenhouses, polytunnels and indoor growing areas.

Can the 3L Round Pot be used with drip irrigation?

Yes. It is suitable for hand watering and compatible drip irrigation systems. Irrigation frequency should be adjusted to crop demand and substrate moisture.

Can the pot be reused?

Yes. Pots that remain in good condition can be emptied, cleaned and reused. Appropriate hygiene is recommended between crops.

Is 3L suitable as a final plant pot?

For many smaller plants it can be. Larger, vigorous or longer-lived crops may need to be moved into a larger container as their root systems develop.
