Ring culture

Tomato plants using ring culture. There is water inside the frame with gravel.

Ring culture is a method of cultivating tomato plants. Tomato plants are grown in a bottomless pot, a "ring", and the pot is partially submerged in a tray of water. Ring culture forces the plants to develop two root systems: one which will absorb the nutrients contained in the soil and another which will absorb the water from the tray.
