How’s a SunCatcher Different?

How Does A SunCatcher Differ From A Typical Greenhouse?

The generally accepted concept of greenhouses is entwined with the era of cheap energy: Do you want to protect your plants? Create a simple structure over them. Make it glass for that cool English look. Make it a Quonset shape with polyethylene for a low budget. Does it get cold? Install a heater. Does it get hot? A huge fan or two will solve that! But those days are over. Today with ever rising energy costs, this “add-on” approach is becoming less and less affordable and practical.

At SunCatcher, we designed an off-the-grid, self-contained passive solar greenhouse to help you grow the way you want – using only seeds, soil, sun and water. We focus on what plants need and designed around maximizing the basic plant needs: heat, sunlight, humidity, CO2 and protection from extreme weather. This approach reduces your distractions so you can focus on what you want to do – gardening and growing food. A few of the key differences to reduce your cost and headaches:


  • Free solar heat stored during the day and released at night by thermal mass, to passively maintain an optimal temperature year round.


  • Strong, well-engineered and permanent, the SunCatcher is built to last for generations with formidable materials, rated for heavy snow loads and hurricane-level winds.


  • Better growing conditions naturally with ambient CO2 and humidity maintained with passive ventilation.

Conventional Greenhouses

  • Expensive heating and cooling with heaters, fans and fuel/power source required, along with maintenance and replacement.


  • Fragile or temporary structure may not withstand strong weather, polyethylene replacement every few years, and expected life span of less than 10 years.


  • Stagnant air is worse for plants with less CO2 and uncomfortable humidity that may cause plant disease, or expensive exhaust fans and CO2 enrichment.
