£1.75

The 25L Round Plant Pot is a large black horticultural grow pot designed for established plants, larger nursery stock, vegetables, shrubs and productive container crops. Measuring approximately 39cm across the upper rim, 31cm across the base and 28.5cm high, it provides a generous 25 litre root volume while retaining a practical, easy-to-manage round format.

A 25 litre container gives established plants considerably more room for root development than standard nursery pots. The larger substrate volume provides increased reserves of moisture and nutrients and creates a more buffered root environment for vigorous or longer-term crops.

The broad 39cm opening provides excellent access for watering, feeding, mulching and top dressing, while the tapered round profile makes the pot suitable for professional nursery production, greenhouses, polytunnels, indoor growing and outdoor horticulture.

Drainage openings in the base allow excess irrigation water to escape, helping maintain the balance between moisture and oxygen required around healthy roots.

Suitable for peat-based and peat-free compost, soil, living soil, coco coir and other horticultural growing media, the 25L Round Pot is a versatile option for both commercial growers and home gardeners.

Generous 25 litre root volume

A 25L container provides substantial space for an established root system to develop. This makes it particularly useful for plants that have outgrown medium-sized nursery containers or require a larger final growing volume.

More growing medium also provides a greater reserve of water and nutrients than a small pot. This can reduce the speed at which the entire root zone dries, although irrigation demand will still vary significantly according to crop size, substrate, temperature and environmental conditions.

For many container-grown crops, 25L can serve as a practical final pot. Very large, vigorous or long-lived plants may eventually require additional root volume.

25L Round Pot dimensions

The pot measures approximately 39cm across the upper rim, 31cm across the base and 28.5cm high.

Its broad 39cm opening provides a substantial surface area for irrigation and makes it easy to apply compost, mulch, worm castings, dry fertilisers and other top-dress amendments.

The 31cm base creates a useful footprint for stability while the tapered sides allow empty pots to nest together for more efficient storage.

What can you grow in a 25L pot?

Twenty-five litres provides enough root volume for a wide range of larger and more vigorous container-grown plants. Typical applications include:

  • Tomatoes
  • Chillies and peppers
  • Aubergines
  • Larger herbs
  • Shrubs
  • Large herbaceous perennials
  • Climbing plants
  • Fruit plants
  • Young trees
  • Ornamental plants
  • Greenhouse and indoor crops
  • Larger nursery stock

The appropriate container size always depends on the species, expected mature size, crop duration and growing method, but 25L provides substantial capacity for many productive and ornamental crops.

Excellent for living soil growing

The 25L capacity makes this pot particularly useful for growers working with living soil and biologically active growing media.

Compared with small containers, the larger soil volume provides more physical space for roots and a larger reservoir of moisture, organic matter and biological activity.

The broad surface is also convenient for adding mulch, compost, worm castings and dry organic amendments during the crop.

For larger plants or long-duration living soil systems, even greater soil volumes may provide additional buffering, but 25L offers a useful balance between root-zone volume and container manageability.

Suitable growing media

The 25L Round Plant Pot can be used with a wide range of horticultural substrates, including:

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

Watering and feeding practices should be matched to the selected substrate. A moisture-retentive compost or living soil mix behaves differently from a highly aerated coco-perlite substrate.

Drainage & irrigation

Drainage openings in the base allow excess irrigation water or nutrient solution to leave the pot rather than remaining trapped around the lower root zone.

Effective drainage is particularly important in a larger container because 25 litres of growing medium can retain a substantial quantity of water. Healthy roots require access to both moisture and oxygen.

When a plant has recently been moved into a 25L pot, its roots may initially occupy only part of the new growing medium. Irrigation should therefore be adjusted to root development rather than automatically saturating the entire container on a fixed schedule.

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

Fits the 40cm Pot Saucer

The 25L Round Plant Pot is compatible with the 40cm Pot Saucer, product code P00082.

The matching saucer measures approximately 41cm across the rim, 37.5cm across the base and 6cm high.

A saucer is particularly useful when the pot is positioned indoors, in a greenhouse or on a surface where irrigation runoff needs to be contained.

In outdoor or free-draining nursery areas, a saucer may not be required.

Ideal for nursery & greenhouse production

The 25L Round Pot provides commercial growers with substantial growing volume while remaining considerably easier to handle than very large tubs and planters.

It is suitable for growing larger nursery specimens, shrubs, productive greenhouse crops and plants that need a substantial final container before sale or planting out.

The simple black horticultural finish provides a clean professional presentation for plants destined for garden centres, landscapers and direct retail.

When should you move a plant into a 25L pot?

Potting-on should be determined by root development and plant requirements rather than following a fixed timetable.

A plant is generally ready for more container volume once its roots have established well through the existing growing medium, the current pot is drying increasingly quickly or the plant requires greater physical stability and root space.

Avoid placing a very small plant directly into 25 litres of wet substrate unnecessarily. Progressive potting can make irrigation management easier while the root system develops.

Practical & reusable

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

Remove old growing medium and root debris before cleaning. Appropriate hygiene between crops can help reduce the risk of transferring pests or plant pathogens.

The tapered profile allows empty containers to nest together, reducing the storage space required between growing cycles.
