The German manufactured Riga Hobby Greenhouse Kit is built to last. 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. It includes (1) roof   vent, (1) large rear wall window, and (1) Dutch door. The Riga backyard   greenhouse has a beautiful "onion-shaped" design, as well as being one of the   sturdiest hobby greenhouses we offer. This is not only attractive but aids in   shedding snow loads. The frame is rustproof, extruded aluminum and working parts   on doors and windows are heavy-duty. The Riga greenhouse features a unique   slide-together "channel" design that allows simple assembly of the aluminum   greenhouse components.
