Q: What size to choose between 30cm and 50cm?
The 30x13xH12cm is the ideal size for standard windowsills (30-40cm wide), small balconies, or narrow window sills. It accommodates 2 to 3 compact plants (aromatic herbs, pansies, succulents). The 50x18xH17cm is made for standard balconies and wider ledges — it is deeper (18cm vs 13cm) and taller (17cm vs 12cm), giving it a much more generous substrate volume for plants like geraniums, petunias, or lavenders. For large spaces, several 50cm planters side by side create a very homogeneous composition.
Q: How does the reservoir work in a rectangular planter with multiple plants?
Same principle as in the round Ethica pot — the reservoir at the bottom diffuses water by capillarity to the substrate. In a planter with several plants side by side, the water distributes throughout the substrate by capillarity — each plant draws according to its own needs. The plants that are more water-hungry (geraniums) take more; the more economical plants (herbs) take less. It is a very natural and very efficient distribution.
Q: Can this planter stay on a balcony in winter?
Yes — triple use including balcony & terrace and outdoor garden. The polypropylene is tested down to -20 °C and treated with UV protection for all three colors. The planter does not crack from the cold and does not fade in the sun. In winter, if very low temperatures are expected, emptying the reservoir prevents any risk of freezing water inside.
Q: What is the difference between this planter and the round Ethica pot from the catalog?
The shape and typical use are very distinct. The round Ethica pot (5 sizes, Ø15→Ø40cm) is designed for a single plant — it conforms to the round shape of the root ball and maximizes the root volume per plant. This rectangular Ethica planter (2 sizes, 30 and 50cm) is designed for linear surfaces — ledges, railings, terrace edges — and accommodates several plants side by side. Both share the same reservoir, the same colors, and the same polypropylene.
Q: Can this planter be used indoors without the risk of overflow?
Yes — the closed reservoir prevents the usual overflow associated with top watering. The water is contained in the reservoir and diffused by capillarity — no saucer needed, no risk of water marks on a windowsill or indoor countertop.
