This 3-season protection tent is designed to fit right inside our Vermont-made 4' x 8' cedar raised beds. The greenhouse cover keeps plants warm on cooler spring and fall days, provides 70% light transmission, 40" of head room at the peak, and has roll-up end windows for ventilation. A second cover protects against ravenous summer bugs and scorching sun. Three zippered doors on each cover provide easy access for tending and harvesting. Tie-downs secure the covers to the steel frame.
