l am in the process of building my base for my new green house 6 foot x 10 foot. l have read in a book that a good ldea is to put sheets of styrofoam around the outside frame of the greenhouse 2 foot deep to keep the cold soil coming into the soil in the greenhouse. Is this safe to do? can or would any chemicals leach from the styrofoam.
