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 coated as not to discolor over the years (guaranteed to contain 0.0% lead), our greenhouse uses on average more than 40 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 8 mm 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 in natural anodized aluminum for long life
  • High impact, UV stable 8 mm commercial grade twin wall polycarbonate walls and roof construction
  • 480 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 6-8 hours to assemble the 8 ft. x 8 ft. greenhouse while using much fewer parts, this does not include the base prep work needed, which includes leveling the ground
  • Automatic opener roof vent (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 8.1 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 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 $100 - $150
  • (new patent pending twist and locksingle 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

Rated 5.0 out of 5 by 1 reviewer.
Rated 5.0 out of 5.0 by Super sturdy and attractive greenhouse We now have fresh vegetables in about two thirds the time it would have outdoors. The bright aluminum finish is very modern and looks great in our back yard. We added the work bench and shade system which has made it easier to garden. August 10, 2012
