Growing seeds in water, or germinating the seeds, begins the growth process of a plant. When water is absorbed, this represents the first sign of germination, since seeds must absorb water in order to begin the process. In order to grow seeds in water, you only need a few materials and a bit of patience to get the process going. In order to speed up the process, soak your seeds in water overnight so that they have a head start on water absorption.
Wet two paper towels with water and place them along the lining of a large beaker so that they stick to the glass. The beaker should be between 6 to 9 centimeters tall.
Fill the space within the beaker with crumpled newspaper so that the paper towels are secured in place on the walls of the beaker.
Pour water in the bottom third of the beaker (2 or 3 centimeters deep).
Place the seeds in between the wet paper towels and the glass walls of the beaker. This is best for pumpkin, kidney, black, white and lima beans, peas and squash seeds. Other types of seeds may require special conditions or treatment of temperature, light and moisture to germinate.
Spray the paper towels with water to maintain the moisture over the next week as you observe the seeds grow, or sprout, inside the beaker. Depending on the type of seeds you are growing, they may take longer than one week. For instance, carrot, parsley and celery seeds are slow growers.
