What we offer is something different from any other greenhouse kit on the market today a lifetime warranty and we feel comfortable offering that because we have the highest quality greenhouses on the market today. This greenhouse is a recreation of the 1940’s Janco greenhouses that are still in service today after 80 years of service. How is that possible? Simple these Greenhouses are made from high quality aluminum using 1/4” and 1/8” thick aluminum members & support beams throughout the structures framing, Stainless steel & aluminum hardware and lastly only tempered safety glass throughout. Using these high-quality materials this greenhouse can never fail and can meet or exceed all local building codes throughout the United states and Canada. Don’t worry about wind, snow, and or storms if our greenhouse is fastened properly to a wood or concrete foundation you won’t have to worry about it falling down or blowing over. All of the cheaper greenhouses are made entirely of plastic, vinyl, or thin aluminum frames that won’t hold up to the elements for long most of these greenhouses last a year or two at best just do yourself a favor and read all the reviews and see for yourself.


  • Passive Solar Ridge Vent
  • Included with Base price

Ingenious temperature-sensitive devices automatically open and close cold frame lids, greenhouse windows and even skylights throughout the day and maintain a constant interior climate, something impossible to achieve by manual adjustments. Requires no batteries or electricity, it starts opening between 55—75°F, depending on how you have adjusted the vent. Strongly recommended for all our glazed season extenders because it dramatically improves plant growth. Screw directly into polycarbonate panels, wood, or metal frames. Use the Standard Vent Opener to lift up to 15 lbs, and the much stronger Gigavent, with all metal construction, to lift up to 65 lbs.
