Very well engineered using durable materials. Very easily assembeled with no specialised tools.
My Rion greenhouse is everything I could want it to be. I was afraid that I would have trouble finding a hobby greenhouse which would withstand high winds and heavy snow. My home sits atop a large hill and wind gusts of up to 70 and 80 mph are a common occurance. We experienced heavy snow fall this winter and my greenhouse roof suported nearly a foot of heavy snow. Heres the kicker. I purchased my Rion Greenhouse used, it is ten years old! I was able to disassemble, transport, and reassemble the complete structure by myself. Durability and simplicity of assembly. I would challange anyone to show me another unit with more value for the dollar!

    Don't buy Rion
    I purchase my Rion Grand Gardener greenhouse a year ago and I have had nothing but problems during the assembly process including broken parts, terrible assembly instructions and poor customer support. My problems began when I received the greenhouse and there were broken parts - which was not a surprise because it is shipped in several large boxes with no packing material for protection. Later during assembly, I broke two parts and in both cases I had a very difficult time with customer support in trying to get the replacement parts - it took several e-mail & phone messages just to get someone to respond! The assembly instruction are not for the faint at heart - in fact they have no "Instruction" at all - just pictures that can be very difficult to interpret. If you can overcome all of this - the end product is a fine greenhouse. I like the dual pane opaque panels, the skylight and louver window features plus the interior height not found on other greenhouses.

    Very Frustrating Experience
    I have had an extremely difficult time with the assembly of this greenhouse. I've done all the recommended "helpful tips" to get the pieces to fit together, double/triple checked the instructions to make sure the pieces they are telling me that are supposed to fit together are indeed the correct ones and yet this has been a very frustrating and bruising experience! While some of the design is easily assembled the "snap in" bracing for the roof is very bad design. This is NOT a weekend project.

    A very durable well engineered construction.
    I was able to purchase a used rion green house, 8 1/2' x 10 1/2'. I was very concerned as to whether it or any other green house would withstand the freaquent 70 to 80 mph wind gusts on top of the hill where I live. I am super impressed with the durability of this structure. It also has withstood the weight of ten inches of wet snow. I truley love my Rion Greenhouse.
