You must lift the container with the nutrient solution just high enough and just long enough to raise the solution around plant roots in the other container, often several times a day. The process can be automated by having the nutrient reservoir set permanently below the plants, with a time-activated pump. Or use a thick polyester rope wick. Put one end in a nutrient reservoir just below the plants and the other end up through the bottom of the plant container, with the rope's end unraveled and fanned out in the growing medium. Organic fish emulsion fertilizer is another option.
Some experimentation is needed to get the right nutrient balance.
