Whether you"re a hobbyist gardener or a serious grower, the Riverstone Industries Monticello 8 x 8 ft. Premium Greenhouse Kit will help you make the most of your horticultural efforts. This modest-sized greenhouse doesn"t take up much room but still allows you to start your plants early and even produce year round. With commercial-grade materials, this greenhouse gives you a safe, sustainable way to extend your growing season. The Monticello Greenhouse by Riverstone Industries uses the highest-quality extruded aluminum available - over 40 lbs. more than an average imported greenhouse of this size. Furthermore, it uses high-impact, UV-stable 8mm twin wall polycarbonate for the walls and roof, whereas most other greenhouses on the market use less expensive materials that they shave down as thin as .2mm. These extra measures of strength pay off by securing your greenhouse and all its precious contents from snow loads up to 24 pounds per square foot and from gusts of wind up to 113 miles per hour, making this far stronger than the average greenhouse. In addition to this obvious ability to hold up under strenuous natural conditions, these high-quality materials also make the greenhouse"s growing potential more efficient, stretching the natural season longer and cutting down on electric bills for those looking to grow year round. As if top-quality materials weren"t enough, Riverstone Industries has also equipped this premium package with a slew of features to help you make the most of your horticultural efforts. This greenhouse"s workbench and sink - the only one found in the industry - will help you plan out your plantings and minimize your work time and effort. Its unique interior shade system will help you prevent sun scorching on more sensitive leaves and flowers, while the automatic roof vents will enable you to keep a good temperature and airflow.
