The Garland Plant Halos offer a watering and crop support solution for popular crops such as tomatoes, peppers and beans. The central inner pot creates the planting area which is particularly useful when used with grow bags as it allows a deeper planting zone to develop healthier plants. A 3 litre outer "moat" features six 2.8cm watering spikes which penetrate below the surface, delivering water direct to the plants roots. This ensures that water and liquid feed are delivered at a reduced rate that the plant is better able to absorb, minimising wastage. It typically takes between 3 and 6 hours for the water reservoir to drain fully, depending on the weather and soil conditions. Dimensions: Dia: 29cm H: 13cm Capacity: 3.1 Litre The Garland Plant Halos can be used on grow bags, pots, raised beds, as well as on traditional vegetable plots.
