Flood & Drain or Ebb & Flow is a long established way to grow your plants hydroponically

Nutrient solution floods your grow bed to a preset level and then either drains away or goes back to a nutrient reservoir, sucking in air to the roots as it goes.

Nutrient can be pumped in at timed intervals, or can be pumped continuously in conjunction with a bell syphon.
