Sub-irrigated planter

Sub-irrigated planter (SIP) is a generic name for a special type of planting box used in container gardening and commercial landscaping.

[1] It is possible to automate the watering and thus SIPs are popular with professional landscapers in buildings or urban settings.

Commercialized versions of a Sub-irrigated planter condenses humidity from the environment and feed it directly into the plants' roots.

SIPs are available as commercial products or as do-it-yourself projects made from plastic buckets,[2] boxes or storage totes.

[3] One of the disadvantages of such closed systems is that soluble salts cannot be flushed into the lower soil profile and build up over time.
