The perfect growing companion for grow bags, large pots or any veg garden, Plant Halos offer an 'all in one' watering and crop support solution for popular crops such as tomatoes, peppers and beans. Plant Halos can be used on grow bags, pots (with a diameter of 26cm and above), raised beds, as well on traditional vegetable plots. The central inner pot creates a deeper planting zone which is particularly useful when used with grow bags as it allows a deeper planting zone to develop healthier plants. A 3.1 litre outer 'moat' features six 2.8cm (1") watering spikes which penetrate below the surface, delivering water direct to the plant's roots. This ensures that water and liquid feed are delivered at a reduced rate that the plant is better able to absorb, preventing wastage which is common with conventional watering. It typically takes between 3 and 6 hours for the water reservoir to drain fully, depending on the weather and soil conditions. Plant Halos also feature a unique cane support system. 3 anchor slots surround the inner pot and provide the means for a rigid, wind-resistant structure using a bamboo cane (not included). A cane grip cap to create a study wigwam is also included and allows for up to 4 canes to be joined (Canes not included). Plant Halos are manufactured from recycled, UV stabilised plastic and are guaranteed for 5 years. Dimensions: 29cm (11½") diameter, 13cm (5") high. Plus an extra 2.8cm (1") Water Spike. Cover Grids for Plant Halos - These cover grids are perfectly tailored for the Plant Halos and prevent dead leaves and foliage from falling into the reservoir. They also prevent pets and wildlife drinking the water and feed intended for your plants. (Pack of 3). Dimensions: 27cm (10½") diameter.
