Round container 18 liter Ø 33 X 29.5 CM

A round plant container of 18 litres, 33 centimetres across and 29.5 centimetres tall, with drainage holes in the bottom and side. Type H 33 LSR, black.

Round or square, at exactly the same volume

This category also carries a square 18 litre pot. Same volume, different shape, and the choice is less arbitrary than it looks.

Square wins on floor use. Square pots meet flush. Push round pots together and a gap is left between every four that you cannot use. Across a full floor that costs you a good twenty percent of your area.

Round wins on moisture distribution. A round pot has no corners, and corners are exactly where substrate stays dry while the rest is moist, and where roots stall. In a round pot every point on the wall is the same distance from the centre.

Round also wins on rigidity. A cylinder holds its shape under the pressure of wet substrate; a square wall bulges slightly. At eighteen litres you notice that when you lift it.

Square wins on storage. Both stack, but square pots nest in a straight column and round ones roll away.

The practical summary: if you are filling a tent floor, take square. If your pots stand apart, outdoors, or on a table where floor space is not the constraint, round is the calmer choice.

What eighteen litres carries

Eighteen litres is a final size for a plant given a full growth phase. At 33 centimetres across it occupies around 855 square centimetres, so nine fit on a square metre touching, with the unusable corners between them.

The pot tapers: 33 centimetres is the measurement at the top. There are drainage holes in the base, so do not stand it flat on a closed surface.

Frequently asked questions

Is the cheaper option per litre always the better one? No, because shape and floor use differ. Choose on your layout rather than on price per litre.

How much substrate does it take? A good third of a 50 litre bag.

Will a plant tray fit under it? Our square trays go up to 29 centimetres, which is too tight for this pot. Use a round saucer or a large catch tray.

How much water per watering? Three to four litres, until something runs out of the bottom.
