There are two ways to start the project: 1) first make a continuous watering planter and plant the seeds and then make the light box a week later or 2) make the light box and then make the planter a week later. There is not enough time in one 2-hour class to do both. If the planter is made first, then the plant has to be kept under a lamp during until next class. A standard white light florescence bulb will work. Fast plant need both light and water all the time, day and night.
