Not all greenhouses are built the same and the Monticello line of greenhouses by Riverstone Industries proves this to be true. The Monticello is proudly MADE IN THE USA, 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 & more brittle foreign aluminum) and electrostatically painted Black (guaranteed to contain 0.0% lead), our greenhouse uses on average more than 55 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 .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 professional grade aluminum frame finished with a rich black electrostatic finish in for long life, entire greenhouse proudly made 100% in the USA
  • High impact, UV stable 8mm commercial grade twin wall polycarbonate walls and roof construction
  • 760 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 hours to assemble the 8ft x 12ft greenhouse WITH THE PREMIUM PACKAGE while using much fewer parts. This does not include the base prep work needed, which includes leveling the ground.
  • Integrated flush base design allows for lower than normal door threshold
  • A -Frame roof optimized heat distribution and with the automatic solar roof ventilation system warm air is removed in warmer months and kept in during cooler months
