drainage
also called drainage system
How a planter handles excess water at its base — drainage-holes (open holes drilled in the base, the standard free-draining pot), removable-plug (base holes fitted with a stopper that opens or seals), self-watering (an integral water-reservoir base that wicks moisture up to the roots), or no-drainage (a solid sealed base, a decorative pot cover / cachepot). This base-water behaviour is the structural differentia of a planter: a planter holds soil and lets excess water DRAIN OUT, the opposite of a watertight UtilityVessel (basin/bucket) which holds liquid IN. Every real planter answers this question (even 'no-drainage' for a cachepot), so it is the kind's required differentia. Distinct from every closure property (A11): `sealing`/`lid_mechanism`/`latch`/`lid_type` are all about the TOP closing or sealing contents IN (food air-tightness, waste disposal opening, storage-lid securing, drinking spout); drainage is the BASE letting water OUT — no shared lexeme, no shared question, never co-occurring. Concern measurement (a kind-specific spec-sheet setting that rides with capacity, the home its four closure-mode siblings sealing/lid_mechanism/latch/lid_type all share — NOT a universal root-Product facet like color/material), axis-eligible (a drainage-holes vs self-watering planter is a genuine buy choice).
Drainage is answered with one word chosen from the drainage types list — the same word shared across every product that uses it.
It belongs to measurement — its measurable, physical facts.
