Passive Solar Greenhouse Design Course

Reap Abundant Harvests Year-Round
in Your Backyard Tropical Oasis


"A passive solar greenhouse combined with a highly productive aquaponic system will provide the most efficient and resilient year round food production possible."

By now you probably already know that a well designed aquaponic system can grow a tremendous amount of food with a fraction of water but...

The problem is traditional greenhouses are notoriously inefficient when it comes to heating and cooling

So why not take it to the next level and combine the best of both worlds?

Now your aquaponics system can produce food for you year-round in the most energy efficient greenhouse environment possible!

Who is this Class For?

Passive solar greenhouses can work just about anywhere but are especially well suited for challenging growing environments such as locations with high altitudes, extreme weather conditions, poor soils or challenging terrains. 

Families  "We want to grow healthy food for our family year round"

The Prepared  "I want to control my own food in the event something happens to our food system"

Retirees "We are looking forward to spending time in our greenhouse growing our own fish and plants"

Health Conscious "We want to make sure we are eating the most nutritiously dense food possible"

Non Profits  "We want to provide food for our community in an environmentally responsible way."

Commercial Growers "Our goal is to grow profitably and reduce our energy costs."

Anyone serious about GROWING MORE FOOD



What You Will Learn

  • How to leverage the “greenhouse self-heating” phenomena with the ground-breaking Ground to Air Heat Transfer system
  • Where to put thermal mass in your greenhouse and why putting it in the wrong place can be catastrophic.
  • A dirt cheap (yet commonly overlooked) step in greenhouse design that is actually KEY in increasing heat retention performance. This applies to simple hoop houses AND 10,000 square foot commercial greenhouses alike.
  • How to use “Strategic Glazing” how to optimize light transmission based on climate, crops, and available materials.
  • Exactly when to ventilate your greenhouse throughout the day based on climate and humidity.
  • Which materials take up no greenhouse space and hold 5x more thermal mass than water.
  • How to design and layout your aquaponic system to maximize use of space and energy

Denver Area Attractions

Have fun and enjoy the beauty during your Denver trip

  1. Stroll through Downtown - Denver’s downtown blends both a Wild West and urban chic vibe. Hit up the 16th Street Mall to browse decades-old bookshops like Tattered Cover and buy cowboy apparel at Rockmount Ranch Wear.
  2. Hike around Red Rocks These gorgeous red rocks jutting from the earth have been graced by thousands of musicians from the Beatles to The Grateful Dead to Depeche Mode. You name it,  they've been there or desperately want to be.
  3. Browse the Denver Botanic Gardens - Whether you’re a nature lover or just like to escape the concrete jungle without leaving city limits, the Gardens are a must-visit.
  4. Indulge your inner foodie at The Source - A 26,000-square-foot, 19th-century warehouse on Brighton Boulevard which was converted to a brand-new marketplace in 2013. The Source features a handful of local brewers, bakers, butchers, specialty grocers and restaurants which purchase produce from Flourish Farm all under one roof, and is one of the city’s hottest destinations for foodies.
  5. Gear up for a game at Coors Field - Watch the Colorado Rockies hit home runs at Coors Field—the park with the highest elevation in Major League Baseball.
