Riverstone Monticello Greenhouse 8x12 - Premium Package

Monticello LogoThe Monticello manufactured and produced by Riverstone Industries has an above-average interior height, going as high as 7ft 6in at its peak which greatly helps in displacing heat, while also allowing tall gardeners to stand straight up inside their greenhouse.

The automatic roof vent openers, the hinged double doors (6ft x 4.4ft) and the built-in rainwater gutter system ensure that you will be able to grow inside your Monticello greenhouse for many years to come.

The Best Feature of all is that your Monticello Greenhouse is backed with the STRONGEST 10YR WARRANTY in the industry; covering not only your frame but also the Polycarbonate sidewalls and roof.

Are you looking for years of hassle-free indoor gardening? Are you looking for a commercial-grade greenhouse in a hobby greenhouse package? Then look no further because with Monticello you get it all.

100% Made In The USAFact: When you buy a Monticello Greenhouse you are buying a Greenhouse that is 100% Manufactured In The USA, by Riverstone Industries, using US Grade Aluminum. A Monticello Greenhouse uses on average 40lbs more aluminum than the average imported greenhouse.

Question: What does this mean for you as the owner?

Answer: It means you are getting a greenhouse that is constructed right here in the USA with the highest quality extruded aluminum, not the more brittle & thinner foreign aluminum. Remember, the weaker the framework the less snow and the less wind it can handle.

Monticello Premium Greenhouse

The Monticello Premium Greenhouse comes with select accessories already included at a discounted price. This enables you to hit the ground running with everything you need to start growing right away.

Fact: Instead of using the thinner less expensive roofing and wall materials(some as thin as .2mm) Riverstone Industries decided to use 8mm twin-wall Polycarbonate which is the same exact thickness used in commercial greenhouses.

Question: How does this benefit me?

Answer: You choose 8mm twin-wall Polycarbonate for the same reason you choose double pane windows. Because it keeps it cooler during the summer and warmer during the winter. Which in turn cuts down your electric bill, if you choose to grow year-round but also provides a more efficient grow environment.

FAQs

Is the frame anodized?

Yes & No. The aluminum frame is anodized. However, the black frame is electrostatically painted.

Is the black paint powdercoated?

No, the black paint is electrostatically applied which is stronger than powder coating. It is very difficult to scratch and should not fade dramatically. Riverstone Industries guarantees it for 10 years.

Is the aluminum frame cooler than the black frame?

Yes, the aluminum frame is on average about 7 degrees cooler than the black.

Can the Monticello be attached to a concrete pad? If so what are the dimensions needed for the concrete pad?

Yes, you can use a concrete pad. Riverstone Industries recommends that you add 3 – 4 inchs to the pad on all sides.

For Example: The 8ft x 8ft (exact size of 8.1ft x 8.1ft) would need a concrete pad of 8.4ft x 8.4ft.

Note: Riverstone Industries does not provide concrete screws, you will need to buy these from your local hardware store.

What tools do I need for the assembly or is everything included?

Not everything is included. Here is a list of tools you will need and items included:

  • Work gloves
  • Safety goggles
  • Spirit level
  • Tape measure
  • Step ladder
  • Clear silicone caulk tube
  • 23 1/8 inch spacer (included)
  • 7/16 wrench (included)
  • Philips screwdriver (included)
  • Flat screwdriver (included)
  • 5-foot bungee cord (included)

Can I extend the Monticello Greenhouse later?

Yes, it is expandable in 4ft increments.

We live in a seismically active area south of San Francisco. I’d like to install the greenhouse on a hill. Is this the best greenhouse for my conditions?

Monticellos are very sturdy greenhouses. However, the greenhouses are not tested for earthquakes. What we can suggest for you to do is to check the bolts and make sure everything is tightened after an earthquake or from time to time. The panels won’t pop out unless the frame is loose. The channels are made to fit the Polycarbonate snugly.

What does the ventilation fan do versus the auto openers in the roof?

Automatic vent openers are self-contained units which require no electricity. It is a temperature-sensitive device that automatically opens and closes a roof vent. So, they release heat and they basically require wind to make the air flow through the greenhouse.

The powered ventilation fan gives you more control. It removes excess heat by creating air movement throughout the greenhouse. However, it’s just a fan, not an AC unit. So, on very hot days, you’ll still experience higher temperatures inside your greenhouse.

Do the doors swing out or slide to the side? What is the door width?

It’s a hinged door so it swings. The door opening is 4ft x 6ft.

Where does it ship from?

Georgia, USA
