Sub-irrigated planter (SIP) is a generic name for a special type of planting box used in container gardening and commercial landscaping. A SIP is any method of watering plants where the water is introduced from the bottom, allowing the water to soak upwards to the plant through capillary action.[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.
