Automated watering and feeding systems for soil, compost and coco mediums. These pot-based kits mean that you save yourself hours of watering and feeding, and that the plants can be left for longer (ie. holidays). Most systems comprise of a reservoir to store a nutrient solution, a pump or valve (no electricity needed), a means of delivery (pipe and/or drippers) and rigid pots. As long as the nutrient reservoir is maintained at the correct level and pH, hassle free growing with consistent yields will result.
