The invention provides a method of plant growing in which method one or more plants are grown in a growing medium comprising hydrogel particles charged with aqueous nutrient solution for the plant and plants, the growing medium being housed in a substantially water-impermeable container and the plants extending out of the container, and, when the water content within the hydrogel particles falls below a predetermined level, introducing further nutrient solution into the container.
