From Germany’s top greenhouse producer comes the Riga V, a complete greenhouse kit for the serious gardener.  This fully loaded greenhouse kit has 165 square feet of floor space and over seven feet of height.  This provides a perfect environment for growing exotic plants, and is large enough to overwinter sensitive outdoor plants as well as store lawn equipment.  

The heavy gauge aluminum framework is perfectly engineered for easy installation and rigidity.  When assembly is complete, this greenhouse is so rigid and structurally sound there is literally no movement front to back or side to side and it can withstand heavy snow loads.

The RIGA is built with extra thick twin wall polycarbonate.  The polycarbonate is 8mm thick on the sides and 10mm thick on the ends.  The twin-wall design coupled with the extra thick panels create an air barrier between the inside and outside of the greenhouse, thus providing superior insulation for the cold winter months. They also reduce damages from extreme heat during the summer months.

In the summer cooling is achieved by multiple solar powered roof window openers and an electric exhaust vent system.  The exhaust vent system is perfectly sized for this greenhouse and consists of an intake vent and an exhaust fan.  This will provide a much needed cross-flow of fresh air.  An appropriately sized heater is also included to keep the greenhouse warm in the winter.  This creates the perfect environment for growing through any harsh weather. Two full length shelves provide a great work surface or place to start seedlings and store tools. The included solar light provides illumination for night inspections. Also included are 5 stainless steel hooks that allow you to hang plants or tie guide wires for growing tomatoes.

This spacious greenhouse allows you to move about freely as you transplant large plants or just spend time relaxing.  The full 7’4” peak height and softly curved shape allows enough room to grow small trees and many oversized tropical plants.
