Unit price perEstimated delivery between November 01 and November 03.
The 12L Round Plant Pot is a versatile black horticultural container for established plants, nursery stock, vegetables and general container growing. Measuring approximately 30cm across the upper rim, 23.5cm across the base and 24cm high, it provides a generous 12 litre root volume while remaining compact enough for straightforward handling and efficient plant spacing.
Twelve litres is a useful intermediate-to-large container size for plants that have outgrown smaller nursery pots but do not yet require very large finishing containers. The additional growing-medium volume provides developing roots with considerably more space while increasing the available reserve of moisture and nutrition.
Its traditional tapered round profile makes the pot suitable for professional nurseries, greenhouses, polytunnels, indoor growing and outdoor horticulture. The wide upper opening also provides convenient access for irrigation, feeding, mulching and surface top dressing.
Drainage openings in the base allow excess irrigation water to escape, helping maintain the balance of moisture and air required within a healthy root zone.
Suitable for peat-based and peat-free compost, soil, coco coir, living soil and other horticultural growing media, this is a practical all-round container for commercial growers and home gardeners alike.

Generous 12 litre root volume
Moving a well-established plant into a 12L container provides substantially more growing-medium volume than smaller nursery pots, allowing the root system to continue expanding as the plant develops.
The increased substrate volume also provides a larger reserve of moisture and nutrients. This can make the root environment more buffered against rapid drying than a small container, although actual irrigation demand will depend on crop size, substrate and environmental conditions.
For many plants, 12L can be used as a substantial growing-on or finishing size. Particularly large, vigorous or long-lived crops may ultimately require a larger final container.
12L Round Pot dimensions
The pot measures approximately 30cm across the upper rim, 23.5cm across the base and 24cm high.
The 30cm upper diameter provides a generous surface area for irrigation and makes it straightforward to apply compost, mulch, granular fertilisers or powdered top-dress amendments.
Its tapered sides combine a stable lower footprint with efficient handling and allow empty pots to nest together for more compact storage.
What can you grow in a 12L pot?
A 12 litre plant pot can accommodate a wide range of established horticultural crops. Typical applications include:
- Shrubs and ornamental plants
- Large herbaceous perennials
- Tomatoes
- Peppers and chillies
- Aubergines
- Herbs
- Climbing plants
- Young fruit plants
- Suitable young trees and nursery stock
- Greenhouse and indoor crops
- General container-grown plants
The correct final container size depends on plant species, expected mature size, crop duration and cultivation method.
Suitable for living soil growing
The 12L capacity provides considerably more biologically active growing-medium volume than small nursery pots, making it suitable for smaller-scale living soil cultivation and organic growing programmes.
Its broad surface provides convenient access for applying compost, worm castings, mulch and dry soil amendments throughout the crop.
Larger living soil systems generally offer greater biological and moisture buffering, so whether 12L is appropriate as a final container will depend on the crop and growing method.
Suitable growing media
The 12L 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
Irrigation and feeding should always be matched to the selected growing medium. A moisture-retentive compost behaves differently from a highly aerated coco or coco-perlite substrate.
Drainage & irrigation
Drainage openings in the base allow excess irrigation water and nutrient solution to leave the container rather than remaining trapped around the lower roots.
Good drainage helps maintain air within the growing medium while reducing the risk of prolonged saturation. This is especially important immediately after potting-on, when the root system may not yet occupy the entire 12L volume.
Irrigation should therefore be adjusted according to root development, crop demand and substrate moisture rather than simply saturating the entire container on a fixed schedule.
The pot is suitable for hand watering, drip irrigation and other compatible nursery or greenhouse irrigation systems.
Fits the 30cm Pot Saucer
The 12L Round Plant Pot is compatible with the 30cm Pot Saucer, product code P00019.
The matching saucer measures approximately 31cm across the rim, 28cm across the base and 5cm high.
Using a saucer can help contain irrigation runoff when the pot is positioned indoors, in a greenhouse or on another surface that needs protection.
In outdoor or free-draining production areas, a saucer may not be required.
Ideal for nursery & greenhouse production
The 12L Round Pot provides a useful balance between generous root volume and manageable overall dimensions.
For professional growers it can serve as a substantial growing-on or finishing container for nursery stock, ornamentals and productive crops while remaining straightforward to move, space and irrigate.
The simple black horticultural finish also provides a clean presentation for plants intended for garden centres, landscaping projects or direct retail.
When should you pot on into a 12L container?
Potting-on is best determined by root development rather than following a fixed timetable.
Plants are generally ready for additional container volume once roots have established well through the existing substrate and the current pot is beginning to dry increasingly quickly between irrigations.
Avoid moving a very small root system into a large volume of growing medium unnecessarily. Progressive potting can make moisture management easier while roots establish throughout the new substrate.
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. Where pots are transferred between crops, appropriate hygiene procedures can help reduce the risk of carrying pests or plant pathogens into the next planting.
The tapered profile allows empty containers to nest together for compact storage.
