Grow Box - Sub-irrigated planter (SIP) by Garden Patch

Sub-irrigated planter (SIP) is a generic name for a 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. SIP's are available as products, under brand names such as EarthBox, Grow Box, Earthainer, or as do-it-yourself projects made from plastic buckets and boxes.

The Grow Box ( "automatically" adds the right amount of water and fertilizer so you never have to guess. Add potting mix, fertilizer, water and sunshine.

The main comparison is between the original EarthBox, Grow Box that copies the system with added reservoir at the front, and DIY SIP (2 5-gallon buckets or 2 storage containers).

Earthbox drips water. There is no such problem with the Growbox. Unfortunately, the Grow Box reservoir is also a breeding area for mosquitos. The Grow Box manufactures sells "Mosquito Dunks" from their website.

Both require potting mixes. EarthBox offers dolomite with the box while GrowBox does not. Azomite is an alternative available from Amazon:
