Backyard Greenhouses Fanatics Guide 2019

Considered “luxuries” far beyond the means of ordinary folks, greenhouses are, in fact, a wonderful healthy endeavour, gardens that thrive year-round and can be as extravagant and pricey or as basic and inexpensive as you want to make them. You deserve quality seasonal produce and a longer growing season in a proper greenhouse. These are some of the many extraordinary benefits of Greenhouse gardening.

The next time you plan to shell out $10,000 on a Christmas present for yourself, there are worse things to choose than a super-lavish “store-bought” greenhouse, with all the comforts of a colony on Mars, complete with an automatic watering system, plant feeders, and ventilation systems.

We have seen those amazing do-it-yourself greenhouse projects on YouTube constructed of wood and old windows salvaged from the local dump. All told the cost worked out to one hundred bucks’ of random hardware and a few weeks of spare-time labour. No more excuses, you deserve the greenhouse of your dreams just like “the other guy” who can afford some fancy kind of greenhouse. Somehow, someway, you can afford one too! If you are a fanatic about gardening (or garden to pay the bills), you deserve the so-called luxury of greenhouse gardening just as much as anyone else!

Why is it better to grow plants in a greenhouse?

Plants subjected to extreme cold and heat across a 24-hour period do not grow as well as greenhouse plants and stressed plants become stunted over time. The enclosed indoor grow space greenhouses provide is typically temperature-controlled with heaters and air ventilation for specific plant species, such as food crops.

What Type of Greenhouse Should You Build?

Factors to consider when buying a particular type of Greenhouse

What type of greenhouse you need depends on where you live and what you intend to grow. These types of Greenhouses are categorized in a variety of ways.

Temperature – The spectrum of structures based on environmental temperature needs include the following:

  • Hot Houses – Temperature: above 16C (60C) Hot greenhouses are used to maintain tropical plants. In order to heat they require supplemental heat.
  • Warm Houses – (Temperature: 13C (55F) Allows for a broader range of plants to survive cold winters.
  • Cool Houses – Temperature: 8-10C (45-50F) This type of greenhouse will maintain temperatures above freezing so that plants that die from the extreme cold can survive.
  • Cold Houses (Propagation)– (Temperature: Falls below freezing) Provide protection for plants, but temperatures still can get below freezing because this type of greenhouse has no additional heat source installed. The purpose of cold houses is to extend growing season in the spring by allowing starting crops earlier and in the fall by allowing crops to grow longer.

Within each of these general types, there are many other considerations to make, from the very simple greenhouses to the high tech ones. The more technology that is involved the greater the ability to precisely control growing conditions including pests, temperature as well as water and humidity levels.

Greenhouses can also be built to minimize direct sunlight (shade greenhouses), or a screen-only structure to keep out insects.

Materials – For the backyard gardener, the choices are almost unlimited. Price will likely drive some of the decision making on this, as well as aesthetic considerations and your overall purpose. All have advantages and disadvantages.

Support/Framework Options: wood (rots quickly), plastic, aluminum, and iron. Some have flat eaves, others have curved eaves.

Covering Options: glass (most expensive but lasts longest, also looks beautiful) a chore to clean, Twin-wall polycarbonate sheet (typical 10-year lifespan), fibreglass (will discolour over time), plastic (cheap but effective), PVC, acrylic (very expensive).

Environmental Control Options – Budget will impact your choices in this area. Automatic controls are ideal in a greenhouse, especially for those who have an active lifestyle away from the home. Options for heating equipment include basic space heaters, forced-air heat, radiant heat, hot-water systems, as well as soil heating pipes underneath plants. Also, a system can be built into the foundation as a thermal mass. Automatic watering systems for greenhouses large and small are nice. Planning ventilation is also essential for plant health.

Design –Design style can also be evaluated, which is the fun part. Traditional types of greenhouse “architecture” include A-Frame, Dome, Gothic (arched), Lean-To (next to a home or garage).
