The German engineered Riga Greenhouses have beautiful and practical designs combined with quality, long-lasting parts and pieces.
Easy to Assemble
The Riga features a sturdy rustproof, extruded aluminum frame. The unique "channel" design of the aluminum components allows for simple "slide and fit" assembly, thus saving time and money. Easy to understand step by step assembly instructions are included with every structure.
With the thickest twin wall polycarbonate offered on a backyard greenhouse, the Riga hobby greenhouse carries the highest R factor of any hobby greenhouse on the market. This makes the Riga less expensive to heat.
Most hobby greenhouses manufactured today offer 4mm or 6mm polycarbonate covering. The Riga hobby greenhouse carries the highest R factor of any hobby greenhouse on the market. It is covered with sturdy 8mm twin wall polycarbonate on the roof and side walls and the end walls are covered with heavy duty 10mm twin wall polycarbonate. This kind of covering provides better insulation making your Riga greenhouse easier to keep cool in the summer and warm during the winter months. The "onion" shape helps shed heavy snow loads.
Doors and Vents
The extra wide 30" heavy duty dutch door with keyed lock is wide enough to easily pass a wheel barrow through. The extra wide 40" x 24" automated roof window(s) and oversized 30" x 42" gable end window maximize the benefits of natural ventilation.
Optional Base Kit (Call to order)
Heavy-duty 6" tall extruded aluminum base for the Riga Greenhouse. Base can be placed directly on ground and if you choose, can be filled with sand, peagravel or concrete. Greenhouse frame slides directly onto base.

We bought this greenhouse in 2013. Delivery was excellent. Everything went together in less than a weekend. This is the one to buy. After eight years it's still in great shape. We installed it on 6 concrete piers (4 corners + 2 on the long sides) make by digging a holes and using concrete tubes from Lowe's. Leveled the tube tops, filled with concrete, let set, then bolted the base down. I added a paver floor and a frost-free hydrant.
After review of many home size greenhouses, picked the riga for efficiency and eligance. Kit arrived quickly with good support. Built in 1 1/2 days w help from two others to piece big sections together on pre-poured concrete stem walls. Result is a very strong, roomy and warm greenhouse. My wife is very hsppy.
