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 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 .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 electro statically painted black
  • 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 8ft x 8ft greenhouse while using much fewer parts. This does not include the base prep work needed, which includes leveling the ground.

Rated 4.5 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Good One The company returned my call about the problems with the directions within an hour and stated that most of the concerns were corrrected since I bought mine. He took all the time I wanted and was very easy to talk to. He thanked me several times for my input. EASY TO DEAL WITH AND A PLEASURE TO TALK TO It was also nice that they furnished a good screwdriver and 7/16 wrench, not some cheapo junk. March 18, 2013
Rated 4.0 out of 5.0 by Bad Directions I have problems with the directions : 1] They are packed in box C and not box A where you would start. 2] On page 21 it says to use B3 but you need to use B2. 3] The pages of the instruction are out of order (35, 38, 36, 37). 4] It would be helpful if the parts were labeled. 5] When calling customer service you get the " Leave a message, we'll call you back" thing. 6] I,m not sure the customerservice email is correct ( ) seems like it should be " " 7] It would be much faster if all parts were labeled. This is a good strong greenhouse, just poor directions March 18, 2013
