1. High Quality 5 Wall Glazing

The high quality POLYCARBONATE GLAZING is a clear, rigid translucent covering that allows 65% light transmission. It resists breakdown by ultraviolet light and harsh weather impacts, like hail. We reduce the cost by using half sheets which would normally end up in the landfill. The angle of the lid is specifically designed for optimum winter growth. Most cold frames do not have this feature.

2. North Wall Insulation

The unique design feature of the North Wall Insulation helps keep “Junior” cozy during the unpredictable cold nights and reflects light evenly onto the plants for maximum growth throughout the day. Most cold frames get hot in the day but at night lose all their heat and your plants can freeze.

3. Automatic Opening Window Vents

Solar powered actuators with wax filled pistons, allow the vent (window) to open at a preset temperature, without the use of any electricity. The window vents close automatically as the temperatures drop, freeing you to go to work or vacation without worry of your plants overheating or freezing.

4. Water Reservoirs

This unusual cold frame feature is a series of water reservoirs that act as the “Power Pack”. The water mass keeps the structure warm in the winter and cool in the summer creating an optimum growing environment. Depending on your climate conditions "Junior" will definitely extend your growing season and potentially provide a space for year-round growth. We use one gallon water jugs, but any dark colored water containers would serve the same purpose.

5. Undersoil Heating/Cooling System

A solar panel produces electricity to power a fan which draws warm air through pipes buried in the raised soil beds. Every day when the sun shines, your soil is being heated! This same system helps to cool the inside in the summer by drawing cooler air through the same pipes, allowing the growing beds to retain more moisture.

6. Insulated Foundation Wall

Growing Spaces “Junior” sits on a foundation wall which raises the cold frame up above the snow. This wall is insulated to prevent the soil in the growing beds from freezing. The wall is lined with sheet metal on the inside and has a bottom plate of pressure treated lumber or redwood for added longevity also has a long lasting decay resistant siding.

7. Perimeter Insulation

If you choose to install this feature it prevents frost from penetrating under the wall. It enables the soil mass to stay warmer during the winter, further extending the growing season.
