This kit includes a greenhouse with a transparent lid, two bags of Wonder Soil (100 mini wafers), three removable six-section trays and an activity guide with reproducible worksheets.  Setting up the greenhouse is simple, making the kit perfect for anyone without greenhouse experience.  Wonder Soil mini wafers expand quickly with water and are polymer-fortified for better drainage and faster plant growth.  The greenhouse measures 5.5" x 22.5" x 6.5".  Launch date: June 2007.
