The German engineered Riga Greenhouses have beautiful and practical designs combined with quality, long-lasting parts and pieces. 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.

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.

Riga Greenhouse Shade Kits are fabricated with 50% Aluminet Shade Cloth and heavy-duty reinforcing tape sewn along all four edges and brass grommets installed every 2' around the perimeter for easy installation using rope or bungee cords.

Good quality, good buy.
Size: 300 Count (Pack of 1,8.375 Inch)
I liked these plates more than I thought I would. The plates hold up well under load and don’t soak through like regular less expensive plates. The size is right for most meals and still not too big for just dessert. They worked great in the microwave and were easy to separate from the stack. These came packed in a box with two stacks that were each wrapped in plastic to keep them clean in shipping and storage. I will buy these again.

Very sturdy material, easy to separate even for a child. The only clean up is when someone bumps into your plate lol. Great price for the quantity.

Not flimsy

These paper plates are sturdy and hold food well without bending or leaking. I originally thought they were going to be a little bigger than they are, but I still ended up keeping them and using them regularly. They work great for snacks, lighter meals, and everyday use. The quality is good, they’re easy to store, and the large pack is very convenient.
