Unit price perEstimated delivery between November 01 and November 03.
The 3L Square Round Plant Pot is a compact black horticultural grow pot designed for efficient nursery production, potting-on and growing established young plants. Measuring approximately 15.5cm across the upper rim, 13cm across the base and 16cm high, it combines the space efficiency of a square pot with a tapered lower profile.
The 3 litre capacity makes this an excellent intermediate container between small propagation pots and larger finishing pots. It provides developing plants with additional root volume while remaining compact enough for efficient greenhouse, nursery and growing-room layouts.
Its square upper profile allows pots to be positioned closely together, reducing wasted space between containers. This can be particularly useful in professional horticulture where maximising available bench and production space is important.
The tapered body helps make established root balls easier to remove during potting-on and allows empty pots to nest together for compact storage.
Suitable for peat-based and peat-free compost, soil, coco coir and other horticultural growing media, this versatile 3L pot can be used for ornamental, edible and nursery crops.
Why choose the 3L Square Round Plant Pot?
- 3 litre capacity - an excellent intermediate pot size for established young plants.
- Square round design - combines efficient bench spacing with a practical tapered root zone.
- 15.5cm upper rim - compact footprint for greenhouse and nursery production.
- 16cm high - provides useful depth for continued root development.
- 13cm base - tapered profile helps with plant removal and storage.
- Space efficient - square upper profile reduces unused space between neighbouring pots.
- Ideal growing-on size - useful progression from smaller propagation and nursery containers.
- Professional nursery format - suitable for production, growing-on and retail presentation.
- Suitable for peat-free media - compatible with modern peat-free growing substrates.
- Suitable for coco - can be used with coco coir and coco-based growing media.
- Indoor & outdoor use - suitable for nurseries, greenhouses, polytunnels, indoor growing and gardens.
- Reusable - sound pots can be cleaned and reused for subsequent crops.
- Compatible saucer available - fits the 14cm saucer, product code P00047.
Space-efficient square round design
Square round horticultural pots combine characteristics of conventional square and round containers.
The squarer upper profile allows neighbouring pots to sit more closely together than traditional round pots, helping growers make efficient use of greenhouse benches, nursery areas and propagation spaces.
The lower section tapers towards a smaller base, creating a practical root-zone shape while allowing empty pots to nest together efficiently.
This combination makes square round pots particularly useful for commercial horticulture where space efficiency, handling and straightforward potting-on are all important.
A versatile 3 litre growing-on pot
Three litres is a useful intermediate container volume for plants that have established in smaller pots but do not yet require a large finishing container.
Moving an established plant into a 3L pot provides additional growing medium for continued root development while keeping irrigation and handling manageable.
The larger substrate volume provides a greater reserve of moisture and nutrients than small propagation pots, helping support increasing root mass and canopy growth.
For compact plants and shorter production cycles, 3L may also be suitable as the final growing or retail container.
What can you grow in a 3L pot?
The 3L Square Round Plant Pot is suitable for growing-on a wide range of edible and ornamental crops, including:
- Herbs
- Chillies and peppers
- Young tomato plants
- Strawberries
- Herbaceous perennials
- Bedding and patio plants
- Young shrubs
- Ornamental plants
- Climbing plants
- Young vegetable plants
- General nursery stock
Whether 3L is suitable as a final container depends on the mature size and vigour of the crop. Larger plants and longer growing cycles may eventually require additional root volume.
Suitable growing media
The 3L Square Round Pot can be used with a broad range of horticultural substrates, including:
- Peat-based nursery compost
- Peat-free growing media
- Soil-based potting mixes
- Compost-based mixes
- Coco coir
- Coco and perlite blends
- Other suitable horticultural growing substrates
Choose a growing medium appropriate for the crop and production system. Watering frequency should be adjusted according to substrate structure, plant size and environmental conditions.
Watering plants in 3L pots
After potting-on, the plant's existing root system may initially occupy only part of the fresh growing medium. Water carefully while new roots establish throughout the container rather than automatically saturating the pot on a fixed schedule.
As root mass and foliage increase, water demand will normally rise. Monitoring the moisture content and weight of the growing medium can provide a more useful indication of irrigation requirements than watering solely according to time.
The pot is suitable for hand watering and compatible nursery, greenhouse and drip irrigation systems.
Fits the 14cm Pot Saucer
The 3L Square Round Pot is listed for use with the 14cm saucer, product code P00047.
The saucer measures approximately 17cm across the rim, 14cm across the base and 2cm high.
Using a saucer can help collect irrigation runoff and protect greenhouse benches, shelving, floors and other surfaces from excess water.
Avoid allowing the pot to remain permanently standing in excess runoff unless this forms part of the intended irrigation method.
When should you pot on into a 3L container?
Potting-on is best determined by root development rather than following a fixed number of weeks.
A plant may be ready for a 3L container when roots have established throughout its existing growing medium, water demand has increased significantly or the plant has become large relative to its current pot.
Moving plants progressively through appropriate container sizes can make moisture management easier and encourage the root system to establish throughout the available growing medium.
Ideal for nursery & greenhouse production
The 3L Square Round Pot provides a useful balance between root volume and production footprint.
Its relatively compact dimensions allow significant numbers of plants to be accommodated within nursery and greenhouse environments while still providing enough substrate for substantial plant development.
As crops mature, pots can be spaced further apart where necessary to improve airflow, light interception and canopy development.
Reusable horticultural pot
Pots that remain in good condition can be emptied, cleaned and reused for subsequent plants.
Remove old roots and growing-medium residue before cleaning. Where pots are reused between different crops, suitable hygiene procedures can help reduce the risk of transferring pests or plant pathogens.
The tapered profile allows empty containers to nest together, helping minimise storage requirements between growing cycles.
