The 5.5L Square Round Plant Pot is a professional black horticultural grow pot combining the space efficiency of a square container with a rounded lower profile. Its 5.5 litre capacity makes it a versatile growing-on and finishing pot for nursery stock, vegetables, ornamentals and established young plants.
Square round pots are designed to make efficient use of valuable growing space. The square upper profile allows containers to be positioned closely together across nursery and greenhouse benches, while the tapered body provides a practical root zone and makes empty pots easy to nest for storage.
At 5.5 litres, this pot provides substantially more root volume than smaller propagation and nursery containers without taking up the space of a large finishing pot. It is therefore particularly useful for potting-on established plants and for crops that require a moderate final container volume.
The black horticultural construction provides a clean, professional presentation suitable for commercial nursery production as well as home growing.
Suitable for peat-based and peat-free compost, soil, coco coir, living soil and other horticultural growing media, the 5.5L Square Round Pot can be used across a broad range of growing systems.
Why choose the 5.5L Square Round Plant Pot?
- 5.5 litre capacity - useful root volume for established young plants and growing-on.
- Square round design - combines efficient bench spacing with a practical tapered root zone.
- Space efficient - square upper profile reduces wasted space between neighbouring pots.
- Excellent potting-on size - useful progression from smaller propagation and nursery pots.
- Suitable as a finishing pot - provides sufficient volume for many compact and medium-sized crops.
- Tapered profile - helps with plant removal and allows empty pots to nest together.
- Professional horticultural format - suitable for nursery, greenhouse and commercial production.
- Suitable for peat-free media - compatible with modern peat-free growing substrates.
- Suitable for coco - can be used with coco coir and coco-based mixes.
- Suitable for living soil - useful for smaller biologically managed growing systems.
- Indoor & outdoor use - suitable for greenhouses, polytunnels, nurseries, grow rooms and gardens.
- Reusable - pots in sound condition can be cleaned and used for subsequent crops.
What is a square round plant pot?
A square round pot combines characteristics of traditional square and round horticultural containers.
The upper section has a predominantly square profile, allowing pots to be positioned efficiently alongside one another. The lower body transitions into a more rounded and tapered form, providing a practical growing volume while retaining the handling and nesting benefits associated with conventional nursery pots.
This combination makes square round pots particularly useful in professional horticulture where growers need to maximise production space without compromising root volume.
A versatile 5.5 litre growing volume
The 5.5L capacity sits between smaller nursery pots and larger finishing containers, making it particularly useful for progressive potting.
Plants that have developed a healthy root system in smaller containers can be moved into 5.5 litres of fresh growing medium, providing substantially more space for continued root development.
The increased substrate volume also provides a greater reserve of moisture and nutrients than smaller pots, helping support established plants as their canopy and root system expand.
For many compact crops and nursery plants, 5.5L can also serve as the final growing or retail container.
What can you grow in a 5.5L pot?
The 5.5L Square Round Pot is suitable for a broad range of productive and ornamental crops, including:
- Herbaceous perennials
- Herbs
- Chillies and peppers
- Young tomato plants
- Strawberries
- Compact vegetable crops
- Young shrubs
- Climbing plants
- Ornamental plants
- Greenhouse crops
- General nursery stock
Whether 5.5L is appropriate as the final container depends on the crop, mature plant size and length of the growing cycle. Larger or particularly vigorous plants may eventually require additional root volume.
Efficient greenhouse & nursery spacing
One of the principal advantages of the square round format is improved use of growing space.
Conventional round pots leave curved gaps between neighbouring containers when positioned closely together. The squarer upper profile of this pot allows containers to be arranged more efficiently across benches and production areas.
This can help growers increase plant density during production while maintaining an orderly layout that is straightforward to irrigate, inspect and manage.
As plants develop, spacing can be increased where necessary to improve airflow and prevent neighbouring canopies from becoming excessively crowded.
Suitable growing media
The 5.5L Square Round Pot can be used with a wide variety 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 frequency should always be matched to the plant and growing medium. A moisture-retentive compost will behave differently from a highly aerated coco or coco-perlite substrate.
Irrigation & root-zone management
A 5.5L container provides considerably more growing-medium volume than a small propagation pot, so watering practices should change as plants are potted-on.
Immediately after transplanting, the root system may occupy only part of the fresh substrate. Avoid keeping the entire pot unnecessarily saturated while roots establish into the new growing medium.
As root mass and canopy size increase, plants will normally use water more rapidly. Irrigation frequency should therefore be based on substrate moisture, crop demand and environmental conditions rather than a fixed timetable.
The pot can be used with hand watering and compatible nursery, greenhouse and drip irrigation systems.
Ideal for professional nursery production
The combination of moderate root volume and efficient square spacing makes the 5.5L Square Round Pot particularly useful for commercial nursery production.
It provides enough substrate for substantial plant development while remaining compact enough for efficient handling, spacing and transport.
The black horticultural finish provides a straightforward professional presentation for plants intended for garden centres, landscaping projects or direct retail.
When should you pot on into a 5.5L pot?
Potting-on should be based on root development rather than a fixed number of weeks.
Plants are generally ready for additional growing-medium volume once their roots have established throughout the existing container, irrigation demand has increased or top growth is becoming large relative to the current pot.
Progressive potting helps maintain manageable moisture conditions. Moving a very small root system directly into an unnecessarily large volume of wet growing medium can make irrigation more difficult to control.
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 containers are reused between crops, appropriate hygiene procedures can help reduce the risk of transferring pests or plant pathogens.
The tapered design allows empty pots to nest inside one another, reducing the storage space required between growing cycles.
