Greenhouse Megastore Junior Series Teaching Package – Finally, a commercial quality greenhouse at a price that will not break your budget. Don’t let the price fool you; the frame of this structure is constructed from the same high quality, galvanized steel roll-formed components as our larger greenhouses. As such, this building can be engineered to meet almost any snow or wind load rating. The 6mm twinwall polycarbonate covering offers an R-Factor of 1.55 which is only 0.02 less than 8mm coverings and comes with the same 10 year warranty. For these reasons and more, this “Junior” Series package is one of our most popular and will offer performance and reliability for generations of students.
