    Made from the highest quality extruded aluminum with a protective coating, this 8' x 20' greenhouse uses on average more than 85 lbs. more aluminum than the average imported greenhouse. This means your new greenhouse can hold up to 24 lbs. per square foot of snow and withstand wind gusts up to 113mph. It also features professional-grade 8mm twin wall polycarbonate panels. This material acts like a double pain window, keeping cooler air in during the warm months and insulating the greenhouse from cold air in the wintertime. This makes the greenhouse great for growing over a longer period of time and also adds to its efficiency, cutting down electric bills for those who choose to grow year round. At 7'6" tall at the peak, this greenhouse boasts an above average interior height that helps displace heat within the greenhouse and allows for the tallest gardeners to work in comfort. Additional features include an integrated base, a built-in rain water gutter system, an automatic roof vent opener and low profile double sliding doors that open to 48"-wide. The complete kit includes the greenhouse, a work bench system, an interior shade system, a programmable watering system and a greenhouse sink system.

    Product Features:

  • High-impact, UV-stable 8mm twin wall polycarbonate walls and roof keep cooler air in during warm months and insulate the greenhouse from cold air in the wintertime

  • Integrated dual rain water gutter system and dual low profile "easy roll" sliding entry doors with locking ability for ease of use

    *Please note, before ordering your greenhouse you must contact your local authorities regarding any required building permits or restrictions.

    When selecting a site for your greenhouse, a flat, level surface is essential. Proper water drainage and easy access to power and water is also necessary for greenhouse gardening. Choose a sunny, level position away from overhanging trees and power lines and protected from the wind as much as possible. The location should be away from structures that could cause snow to drift on or around the greenhouse. Locate underground pipes or cables before preparing the site or anchoring the greenhouse.

    After choosing a location, proper preparation of the site is essential. The site must be level. The greenhouse must be mounted to a base. Construct the base first so the greenhouse can be securely mounted. Riverstone recommends constructing a wood platform base using a perimeter of 2 x 4s filled with either soil, sod or gravel. Instructions for constructing a wood platform can be found in the product manual.

    Other suitable base options include wood decks and concrete slabs. Wood screws are included to secure the greenhouse to a wood base. The greenhouse is secured to the ground from the inside with ground anchors. See product manual for details. If you are using a concrete base, appropriate mounting screws (not included) must be purchased before beginning.

    Make sure the corners are square by measuring the inside diagonals from both sides and making sure they are equal. Use a spirit level (not included) to make sure the base is level.
