Questions & Answers


Need a 4 ft extension to add to 8×8

Asked by Red March 5, 2021

When will you have them in stock

Asked by Kathi September 14, 2020

Are the roof vents automatic?

Asked by jim May 9, 2020

No. Manual. But that's a nice idea...attach a motor to open / close it, with a timer or controlled by a thermostat. Maybe invent one!

Can you safely heat in the winter?

Asked by greenhouse March 15, 2020

Yes , with a temperature controlled unit.

What is the thickness of the side panels? Are they twin wall sides?

Asked by Joey September 26, 2019

Hi Joey, The side panels are virtually unbreakable, high impact single layer polycarbonate 0.7 mm. Thanks and have a wonderful day!

Where/how do you purchase the optional base? And how much does it cost?

What is the difference between the two 8' * 12' models? (#702497 versus #702493)

Asked by Kate September 21, 2016

Hi Kate, The main difference between the two 8 x 12 models is in the panels, one has crystal-clear polycarbonate panels which provide high light transmission and the other has twin-wall polycarbonate panels which provide diffused light. Thanks and have a wonderful day!

approximately how long does it take to put together and if you do not pour a slab how do you anchor?

Asked by Vic November 10, 2015

Realistic time is 2 weeks. The base was anchored to 6 x 6 timber and is rock solid.

is there any wind load data

Asked by Lloyd September 18, 2015

The maximum wind resistance is 55 MPH.

The installation was relatively smooth. Careful attention to the instructions is required. Customer support was very helpful when parts had to be replaced. Kudos for the overall fit of components. The further into the installation the stronger the unit became. We will need to install an exhaust fan to draw the heat out. The roof vents are not enough to regulate temperature. The one caveat don't be mislead by the videos and assembly time. which says completed in 2 days , 2 weeks is more realistic. But in the end the Rion appears to be a solid product. It has already withstood some high wind conditions with no damage.

Very dissatisfied with this product. Very cheaply made for the large amount of money it costs. I would NOT recommend this product to anyone. Advertising is very misleading, it is NOT quick and easy setup. States lock and pin system, unfortunately you find out after its been delivered what their version of that means. I have wasted almost $2500 on a flimsy cheap greenhouse.

I think this product is great but there were a few issues preventing a five star review. Can’t go into detail with only 300 characters here, but I’d just say if you are not mechanically inclined do not attempt to assemble this. Unpacking and labeling everything is important!!

Follow the directions completely in detail
This is not a product for someone that cannot follow pictures in detail. There are about 500 parts to this thing and if you don't follow the directions step by step, I doubt that you would ever get it together. I like the finished product and it faired well in 30 mile per hour winds and rain with no leaks. The shipping quality was great, only one incorrect part.
