The 6.5L Square Plant Pot is a strong, reusable black plastic grow pot designed for efficient container growing in nurseries, greenhouses, grow rooms and home gardens. Its space-saving square profile allows pots to sit closely together while the deep container provides useful root volume for established plants.
Made from robust recycled plastic, this practical 6.5 litre pot is suitable for repeated use and provides a cost-effective alternative to lightweight disposable growing containers.
The square shape makes particularly efficient use of growing space. Unlike round containers, square pots can be positioned closely together with considerably less unused space between them, helping maximise the number of plants that can be accommodated on benches, floors and growing areas.
Pre-formed drainage holes in the base allow excess irrigation water to escape from the growing medium, helping maintain an appropriate balance between moisture retention and root-zone aeration.
Suitable for use with soil, peat-based compost, coco coir and compatible soilless growing media, the 6.5L Square Pot is a versatile choice for both professional horticulture and home growing.

Square pots make better use of growing space
One of the main advantages of a square plant pot is the efficient use of available floor or bench space.
Round pots naturally leave gaps between neighbouring containers. Square pots can be arranged much more closely, allowing growers to make better use of propagation benches, greenhouse staging, grow-room floors and other production areas.
This becomes increasingly useful when managing larger quantities of plants, where even small improvements in spacing can make a significant difference to the overall capacity of a growing area.
The regular square footprint also makes it easier to organise plants into neat rows for irrigation, maintenance, movement and crop management.
6.5 litres of practical root volume
A 6.5L pot provides considerably more growing-medium volume than smaller propagation and early-stage containers while remaining compact enough for efficient plant spacing.
This makes it useful as an intermediate or finishing container for a wide variety of plants, depending on species, crop duration and required final plant size.
The relatively deep profile provides useful vertical root space, while the drainage openings help prevent excess irrigation water from remaining trapped at the bottom of the container.
Ideal for professional horticulture & home growing
The straightforward design makes this pot suitable for a broad range of growing environments.
Nurseries & commercial growers
Square pots help maximise bench and production-space utilisation while providing a durable container that is easy to handle and arrange.
Greenhouses & polytunnels
The 6.5L capacity provides useful root volume without requiring the footprint of a much larger finishing pot.
Indoor growing
Square containers make particularly efficient use of enclosed growing areas where available floor space is limited.
Gardens, patios & allotments
The pot is equally suitable for general container gardening, vegetables, herbs, ornamentals and other appropriate crops.
Drainage & irrigation
Drainage openings in the base allow excess water and nutrient solution to leave the growing medium rather than remaining trapped around the lower root zone.
Effective drainage is particularly important with frequently irrigated crops and free-draining substrates such as coco.
Where runoff needs to be collected, the pot can be positioned over a suitably sized plant saucer, drainage tray or irrigation collection system.
Never assume that a larger pot automatically needs more frequent irrigation. Watering should be based on the moisture content of the substrate, root development and crop demand.
Strong, practical & reusable
These square pots are manufactured for practical growing rather than decorative use. Their robust plastic construction allows them to withstand the routine handling associated with potting, moving, irrigation and crop maintenance.
After a crop has finished, sound pots can be emptied, cleaned and reused. Where pots are being transferred between crops, appropriate cleaning and hygiene procedures should be followed to avoid carrying root debris, pests or pathogens from one crop to another.

6.5L Square Plant Pot FAQs
What is a 6.5L square pot suitable for?
A 6.5L pot provides a useful intermediate amount of root volume and can be used for a wide variety of vegetables, herbs, ornamentals and nursery crops. Suitability for finishing a plant depends on the species and expected final size.
Why use square plant pots instead of round pots?
Square pots can be positioned closely together with less unused space between containers. This makes them particularly efficient on greenhouse benches, nursery beds and indoor growing areas.
Does the 6.5L Square Pot have drainage holes?
Yes. The pot has pre-formed drainage openings that allow excess irrigation water to drain from the growing medium.
Can this pot be used with coco coir?
Yes. The 6.5L Square Pot is suitable for coco and coco-based substrates. Irrigation frequency should be adjusted to suit the drainage characteristics of the substrate and the needs of the crop.
Can I use this pot with normal compost?
Yes. It can be filled with conventional potting compost, peat-free compost, soil-based mixes and other suitable horticultural growing media.
Is the 6.5L Square Pot suitable for living soil?
Yes. Living soil can be used in the pot, although growers should consider whether 6.5L provides sufficient soil volume for their particular crop and biological growing method.
Can the pot be used outdoors?
Yes. It is suitable for outdoor gardens, patios and allotments as well as indoor grow rooms, greenhouses and polytunnels.
Is this pot suitable for professional nurseries?
Yes. Its square footprint, practical capacity and reusable construction make it suitable for nursery and commercial horticultural applications as well as home growing.
Are square pots good for greenhouse benches?
Yes. Their straight sides allow efficient spacing and neat layouts, helping growers make better use of available greenhouse bench area.
Can the 6.5L pot be reused?
Yes. Pots that remain in good condition can be cleaned and reused. Good crop hygiene is recommended before transferring containers between plants or production cycles.
Do I need a saucer underneath the pot?
Not necessarily. A saucer or drainage tray is useful where runoff needs to be collected, particularly indoors or on protected surfaces. In free-draining production areas, runoff may instead be managed by the growing system.
Is a 6.5L square pot suitable for automated irrigation?
Yes. Square pots are commonly used with drip irrigation and other automated watering arrangements. Irrigation volume and frequency should be matched to the crop and growing medium.
Is this a decorative planter?
No. This is a functional horticultural grow pot designed primarily for plant production and container cultivation rather than decorative display.
What are the advantages of a deeper square plant pot?
A deeper profile provides useful vertical root space while maintaining a relatively compact footprint, making it useful where growers want reasonable substrate volume without sacrificing too much growing area.
