£0.45

The 7.5L Round Plant Pot is a practical black horticultural grow pot for established plants, vegetables, ornamentals and nursery stock. Measuring approximately 25cm across the upper rim, 20cm across the base and 21cm high, it provides useful root volume while retaining a compact footprint.

With a nominal capacity of 7.5 litres, this pot sits between smaller propagation and growing-on containers and larger finishing pots. It is particularly useful for plants that have established well in smaller containers and need additional root space for continued development.

The traditional tapered round profile makes it suitable for professional nursery production as well as greenhouse, polytunnel, indoor and outdoor growing. It can be used with peat-free compost, peat-based substrates, soil mixes, coco coir, living soil and other suitable horticultural growing media.

Its broad opening provides easy access for planting, watering and top-dressing, while the tapered sides make established root balls easier to remove when plants need transplanting or potting-on again.

Why choose the 7.5L Round Plant Pot?

  • Indoor & outdoor use - suitable for nurseries, greenhouses, polytunnels, grow rooms and gardens.
  • Reusable - sound pots can be cleaned and reused for subsequent crops.
  • Compatible saucer available - fits the 30cm saucer, product code P00019.

What can you grow in a 7.5L pot?

The 7.5L Round Plant Pot is suitable for a broad range of established edible and ornamental plants. Typical uses include:

  • Chilli and pepper plants
  • Compact vegetable plants
  • Established culinary herbs
  • Strawberry plants
  • Young tomato plants
  • Herbaceous perennials
  • Seasonal flowering plants
  • Young shrubs
  • Climbing plants
  • General nursery stock

Whether 7.5L is suitable as the final container depends on the mature size and vigour of the plant. More vigorous crops can use the pot as an intermediate stage before moving into a larger final container.

Ideal for potting-on established plants

A 7.5 litre container provides a useful step up for plants that have developed a healthy root system in smaller pots.

Increasing the available growing-medium volume gives roots additional space to develop and provides a larger reserve of moisture and nutrients. Avoid moving very small plants into unnecessarily large volumes of wet substrate, as their limited root systems may initially use water relatively slowly.

When potting-on, position the existing root ball at an appropriate depth, fill around it with fresh growing medium and water sufficiently to settle the new substrate.

Suitable growing media

The 7.5L Round Plant Pot can be used with a wide range of horticultural substrates, including:

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

Choose the growing medium according to the crop and cultivation method. Good drainage, moisture retention and root-zone aeration should all be considered when selecting a substrate.

Watering plants in 7.5L containers

Watering frequency depends on plant size, root development, substrate, temperature, airflow and light levels.

Recently transplanted plants may initially occupy only part of the available growing medium. Irrigation should therefore be matched to the developing root system rather than repeatedly saturating the entire pot unnecessarily.

Once fully established, plants can use water considerably faster, particularly during warm weather and periods of rapid growth, flowering or fruit development.

The pot is suitable for hand watering as well as compatible drip and automated irrigation systems.

Fits the 30cm Pot Saucer

The 7.5L Round Plant Pot is listed for use with the 30cm saucer, product code P00019.

The compatible saucer measures approximately 31cm across the rim, 28cm across the base and 5cm high.

A saucer can help collect excess irrigation water and protect greenhouse benches, floors, shelving, patios and other surfaces from runoff.

Unless the chosen growing method specifically requires standing water, avoid leaving the root zone permanently sitting in stagnant runoff.

Professional nursery & greenhouse grow pot

The 7.5L size combines useful growing volume with a relatively compact footprint, making it suitable for commercial nursery production and growing-on established stock.

Its round format makes plants straightforward to arrange and reposition as crops develop. Increasing spacing where necessary as foliage expands can improve airflow, light interception and access for watering and maintenance.

The tapered profile also allows empty pots to nest together, reducing the amount of storage space required between production cycles.

Reusable horticultural plant pot

Pots that remain in sound condition can be emptied, cleaned and reused for subsequent crops.

Remove old growing medium and root debris before cleaning. Where pots are reused between different plants or production cycles, appropriate hygiene procedures can help reduce the transfer of pests and plant pathogens.

What can I grow in a 7.5L plant pot?

It is suitable for many chillies, peppers, herbs, compact vegetables, flowering plants, perennials and young nursery plants.

Is a 7.5L pot suitable for chilli plants?

Yes. A 7.5L container provides useful root volume for many chilli and pepper plants, although particularly vigorous plants may benefit from a larger final pot.

Can tomatoes be grown in a 7.5L pot?

Young and compact tomato plants can be grown in 7.5L containers, although vigorous varieties will often benefit from additional root volume as they mature.

Can I use peat-free compost in this pot?

Yes. The pot is suitable for peat-free compost and other appropriate horticultural growing media.

Can I use coco coir in a 7.5L pot?

Yes. Coco coir and coco-based substrates can be used, with irrigation and nutrition managed appropriately for the chosen system.

Can I use living soil?

Yes. Living soil can be used where 7.5 litres provides suitable substrate volume for the plant and cultivation method.

Is 7.5L suitable as a final plant pot?

For many medium-sized plants it can be. Larger or particularly vigorous plants may eventually require a bigger final container.

When should I move a plant into a 7.5L pot?

Consider potting-on when the plant has developed a healthy root system throughout its existing container and needs additional growing-medium volume.

Is the 7.5L pot suitable for nursery production?

Yes. Its manageable footprint and useful growing volume make it suitable for growing-on a wide range of professional nursery stock.

Can this pot be used outdoors?

Yes. It is suitable for outdoor container growing as well as greenhouses, polytunnels, nurseries and indoor growing environments.

Yes. Pots that remain in good condition can be emptied, cleaned and reused for subsequent plants.

Is a 7.5L pot a good intermediate growing size?

Yes. It provides a useful step between smaller propagation or nursery pots and larger finishing containers, allowing plants additional root space without immediately moving into a very large pot.
