Bittersweet’s WISDOM classes will include many aspects of horticulture. One of our first offerings in the area of horticulture is this course. Hoop houses are year-round, unheated greenhouse-type structures that are a mainstay of Bittersweet’s horticulture program. You’ll learn all about how hoop houses work, the many benefits they provide, and a sample planting schedule. With hoop houses, you can grow year-round, even if you have very cold winters, like in Ohio.
