Product Overview

Not all greenhouses are built the same and the Monticello line of greenhouses by Riverstone Industries proves this to be true. The Monticello is applying good old American ingenuity to make the best product for our customers and help to elevate the industry standards of all greenhouses. Constructed from the highest quality extruded aluminum (US grade - not the thinner and more brittle foreign aluminum) and electrostatically painted Black (guaranteed to contain 0.0% lead), our greenhouse uses on average more than 70 lbs. more aluminum than the average imported greenhouse. Why is this important. The weaker the framework the less snow the greenhouse can hold in the winter time before collapsing on itself also the easier it will be get damages in wind. While most hobby greenhouses on the market us less expensive thinner walls and roofing materials (the crystal clear walls are as thin as 0.2 mm), the Monticello uses professional grade 8mm twin wall polycarbonate. This is the same thickness as used in the commercial greenhouses. The twin wall polycarbonate acts as a double pain window keeping cooler air in during warm months and insulating the greenhouse from cold air in the wintertime. This not only makes the Monticello more efficient to grow in for a longer period of time than other greenhouses but it also adds to the efficiency of growing, cutting down electric bills for those who choose to grow year round.

  • Heavy duty extruded aluminum frame construction finished with electrostatic ally applied black paint for long life
  • High impact, UV stable 8mm commercial grade twin wall polycarbonate walls and roof construction
  • 960 cu. ft. of space, plenty of space to grow your plants and vegetables
  • Through a combination of using superior materials that are more rigid and creating interchangeable parts in our design the Monticello takes the average gardener 10-12 hours to assemble the 8 ft. x 16 ft. greenhouse while using much fewer parts, this does not include the base prep work needed, which includes leveling the ground
  • 3 automatic opener roof vents (2 ft. x 2 ft.) opens and closes based on interior temperature to help prevent plant wilting and dry out
  • Integrated flush base design allows for lower than normal door threshold
  • A-frame roof design to optimize heat disbursement along with roof joist supports that double as hanging plant rods
  • Hinged lockable double doors
  • Greenhouse dimensions: 8.1 ft. W x 16.3 ft. L x 7.6 ft. which includes thoughtfully appointed structure including built in dual rain water collection system gutters
  • Solid commercial grade aluminum along with polycarbonate walls and roof construction assures no rust to the greenhouse
  • 10-year limited warranty on the entire greenhouse the strongest in the industry
  • Expandable can be expanded by using the mont-4-AL expansion kit which allows your greenhouse to grow as your needs do
  • Efficient average cost to run greenhouse year round ranges from $150 - $200
  • New patent pending twist and lock single bolt (makes assembly quicker and easier over prior version) (new for 2014)
  • Please note - allow for a full weekend to fully assemble (ground prep included), 2 people suggested for assembly, manual is fully illustrated

8 ft. x 16 ft. Black Greenhouse is rated 2.3 out of 5 by 3.
Rated 5 out of 5 by from The 16ft version of the Monticello is very nice and roomy. My organization helps educate school... The 16ft version of the Monticello is very nice and roomy. My organization helps educate school age children with how to grow food and eat healthier to allow them to make healthier decisions in life. We have to date purchased 6 of the Monticello greenhouses in 3 different sizes. The 16ft has been the most functional size for us. Assembly was not bad. I would recommend looking at the Mojave model of the Monticello as this comes with a solar fan system which makes a big difference in the summer months with keeping the greenhouse cool enough to grow in and keep the kids interested. We have both a black and silver frame in this size and feel the silver helps to keep the greenhouse a little cooler. If you plan to use this when it is warm out I would tell you to buy a silver frame version. Overall the greenhouse has been great for our program and as we continue to expand we will continue to buy Monticello greenhouses.

Rated 1 out of 5 by from Though itwould be better quality for the price Extremely difficult to assemble. I have a construction background and I had 25-30 hours putting it together. They use this tiny cam lock bolt for everything but it will not lock in place. The brackets are on the wimpy side and in several cases an inch too short. I will probably buy some other brackets and beef it up. Bottom line is that the green house is not a very skookum product. Probably would not take another one if it was free.

Rated 1 out of 5 by from WOW!!!!! My husband bought this for mothers day/ birthday and I have to say it was a huge mistake. It is a major pain in the butt to put together and in my opinion they should come and install the thing for the price we paid. Very, very dissapointed.
