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)

Riga Base

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.

  • Very Well supported product
    This is a very rigorous assembly, not for the feint of heart. The written instructions are useless, however there is a very useful video. We watched the video repeatedly. It took my son-in-law and I two solid days to assemble. This is not a piece of cake, however, it is very well supported by the distributor and i would do it again. This is a very robust greenhouse. It is built of Lexan double glazing and it is amazingly strong. It is also very accurate, all the holes line up exactly.
  • Nice, but a few issues
    Its a great greenhouse, but watch the DVD a couple times before you try and assemble it. Our DVD was damaged so we tried to assemble off the written instructions. Not recommended. We set ours on a 6x6 pressure treated base with pea gravel. Makes for a nice work surface. The automatic window opener is really great the way it functions. Overall I will get years of enjoyment from this greenhouse.
  • loven green
    You got it.. this is the best add on to our home.. this Riga green house is great. The plants are doing great and are keeping warm. With being 20 out side the green house stays 60 or above with a small 1500 watt heater with blower and two sets of lights. We looking forward to getting another Giga for a hot tub. Look at the pictures we entered below and you will under stand why this greenhouse is the best greenhouse you will ever need.
