The Riga Greenhouse is one of the sturdiest on the market, it has been tested against winds up to 100 miles per hour and has never been blown away (when properly anchored to the ground). No eaves aids in shedding snow loads. The Riga Hobby Greenhouse comes standard with 8mm polycarbonate on the roof and sidewalls and 10mm twin wall polycarbonate on the endwalls. No other hobby greenhouse kit on the market comes standard with this kind of insulation. The heavy duty lockable Dutch door offers increased ventilation options while preventing the unwanted access of animals and pests. The doorframe is a wide 29.6 inches, wide enough for a standard wheelbarrow. The Riga Series is the only greenhouse with an oversized, hinged, rear wall window at 42″ tall and 30″ wide and an oversized roof window 40″ wide and 24″ deep (equivalent to 2 regular size roof windows).
