1: In a glass of water, put the sponge in and soak for at least 2 hours.
2: After soaking, return the sponge to the bottom of the "pot" and lay the seeds on the sponge.
3: Drop in about a quarter of a teaspoon of water a day to keep the sponge moist (icky word warning).
4: After 5-10 days, the plants begin to grow and sprout the appropriate temperature at around 60 degrees Farenheit.
