Self-watering supplies the plants with water from below, from a reservoir in the bottom of the planter, so you only need to top up the water about every four weeks. Read more and see the assembly instructions on the Self-watering page, or see planters with self-watering.

Yes, the planters and modules can be extended and built on top of each other. See the support video under assembly videos. If you need extra stability, you can add further reinforcement and use self-tapping screws.

Yes. The side panels are sold in packs of 2, so you can change the size or build together with new modules. Try Design your own.

25 cm for herbs and summer flowers, 40 cm for lettuce and the kitchen garden, 50 cm for deeper roots, 80 cm as a working height and for shrubs.

On soil and gravel: without a base. On a terrace, tiles and balcony: with a base, on wheels or on legs.

The soil requirement is listed under Specifications for each size. As a rule of thumb: width × length × height in metres × 1,000 litres.

We offer a 10-year rust warranty on all painted aluminium parts. Components such as wheels, wooden parts and legs are not covered by the rust warranty, but are covered by the standard 2-year statutory warranty right.

Aluminium is extremely corrosion-resistant, and paint bonds far better to aluminium. Painted steel risks "flaking off" in flakes, and scratches can open the way for rust attacks, so clear rust formations can be seen.

Yes, that is no problem. However, we recommend that the surface is level and sufficiently supported before the planter is installed.

Yes, the base plate used for our planters has holes for draining water.

Most of our products are modular and ready for assembly, designed to be easily clicked together. They are packed flat in cardboard boxes and sent with ordinary parcel services. Assembly instructions are printed directly on the boxes, and the packages are easy to handle and carry.

Our aluminium planters require minimal maintenance and can stay outdoors all year round without any problem. Avoid removing dirt with a brush or similar. Instead, rinse the planter with plenty of water and use a soft cloth or sponge to avoid scratches.

We do not recommend using a grass trimmer close to planters in black aluminium, as the risk of scratches is high.
