Autopot 4 Pot Window Box

The patented Smart Valve design allows only enough nutrient into the medium as the plant requires. The unique system allows maximum nutrient uptake with no waste. As the medium beings to dry out the Smart Valve® allows water and nutrients into the medium at a set level.
The 4 Pot Window Box is suitable for growing herbs and decorative flowers. It works on the same principles as the Autopot Pot Systems.
