Container square 6l 18 x 18 x 23cm
The square pot 6 litres (18x18x23cm) ranks among the most widely used container sizes in indoor growing and belongs in every serious cultivation setup. This volume supports a full vegetative phase and doubles as a suitable final container for medium-sized plants during flowering. The robust build and square profile ensure a stable, space-efficient arrangement in any grow tent or grow room. With 23 cm of depth, roots develop both laterally and vertically for a powerful above-ground canopy. Pair with the 23 cm square saucer for effective drainage control.

Square Pot 6 Litres – Versatile Grow Container 18x18x23cm
If one container size belongs in every indoor grower's toolkit, it is the 6 litre square pot. At 18x18x23cm, it strikes the optimal balance between root volume and spatial efficiency. Whether you grow in soil, coco or perlite, this pot adapts to both the vegetative phase and flowering of medium-sized plants.
The indoor growing standard
The 6 litre pot is the benchmark container for indoor cultivation. In a 100x100 cm tent, 25 of these pots (5x5) align perfectly, producing an even canopy. The volume is sufficient for a dense root ball while still allowing multiple plants side by side in a compact footprint.
- Vegetative phase: comfortably supports 3 to 5 weeks of growth before initiating flower.
- Flowering: for medium-sized plants, this pot can serve as the final container with strong results.
- SOG method: popular with growers running many smaller plants for an accelerated harvest cycle.
Drainage management
Always place a 23 cm square saucer under your pot to collect runoff. This keeps your grow space dry and prevents roots from sitting in standing water. Monitor drainage closely, especially when using moisture-retentive substrates.
The rule of thumb is that every 5 litres of container volume supports approximately 20 cm of above-ground growth. With 6 litres, you can grow plants to roughly 25 cm before flipping to flower. For larger plants, consider the 11 litre square pot for additional root volume and a more vigorous final plant.
The 6 litre square pot is available at plantandflower.be with fast delivery throughout Belgium. A reliable container for every committed grower.
Can the 6 litre square pot be used as a final container?
Yes, for medium-sized plants and autoflowers, 6 litres is adequate as a final container. For larger plants requiring an extended vegetative phase, an 11 litre pot or bigger is recommended. The choice depends on your growing method: for SOG with many small plants, 6 litres works perfectly.
What is the difference between a 6 litre square pot and a 7 litre round pot?
The round pot holds slightly more volume, but the square pot utilises grow tent floor space far more efficiently. Square pots align with zero gaps, allowing more plants per square metre. The corners also promote better root branching rather than the circular root patterns typical in round containers.
Which substrates work in the 6 litre square pot?
All common substrates perform well in this pot: potting soil, light mix, coco, perlite or blends. With coco and perlite, irrigate more frequently with nutrient solution. With soil or light mix, water less often and rely more on the organic nutrients in the substrate.
