Get dirty, have fun and grow more food with great gardening tips from real-life gardeners.
Who doesn’t want a plateful of nutritious, fresh food each day? Many consumers realize that growing their own food and owning a greenhouse may offer year-round vegetables and fruits by extending the growing season in even the coldest of climates. Build.Sow.Grow recommends you consider these seven points to lead you to a successful greenhouse construction.
What is Your Solar Exposure?The very first thing to consider is the sun’s annual path on your property to determine if you have adequate daily exposure to the sun and southern sky. A passive solar greenhouse needs good southern exposure without extensive shading from trees or nearby buildings. The primary resource for heat and light in any greenhouse is the SUN. Without proper sunlight, you will be spending way too much money and resources on auxiliary heating and lighting.
What are Your Property Restrictions?
When building within a neighborhood, you may need to consider HOA design guidelines and covenants or city and county property setback regulations. Some of their parameters may include matching your home’s exterior finishes, size limits, property setbacks, and number of structures allowed on your lot. On a recent greenhouse build, Build.Sow.Grow had to present before a design review board which required matching the siding, exterior colors, roofing materials and finishes of the existing home to receive approval. The results gave a very unified look to the property.
Will You Need a Building Permit to Build Your Greenhouse?
Another important step is to determine if you need a building permit, which are typically mandatory when a structure reaches a specific square footage size. For example, in Gunnison County, Colorado structures under 120 square foot do not require a permit.If your greenhouse requires a building permit, a licensed structural engineer will most likely need to engineer and stamp your plans. It also means you will need to hire licensed trades people for systems such as electrical and plumbing as their work would need to be inspected by the proper building authorities.
What Size Greenhouse Would You Like to Have?
After checking for possible size restrictions, take into account:
a. the number of people for which you’ll be growing food,
b. the variety of foods desired,
c. the types of plants to be incorporated (fruiting shrubs or trees will require more space), and
d. the desire for a dual-purpose space.
What is the Purpose of Your Greenhouse?
Determining the intention of your greenhouse is essential to the design process. It can be a season extender or a year-round growing site. Botanical options can include seed starting, food provision, and flower growing. Beyond the obvious cultivation of plants, aquaponics, vermiculture and composting operations may also be incorporated. If attached to a building, excess heat can be vented inside to provide extra heat and humidity in cold, dry months. Build.Sow.Grow’s latest greenhouse is being used as a home office and reading retreat. Ideas for other dual-purpose functions include a spa space, yoga platform, sleeping loft and meditation room.
What is Your Time Commitment?
Maintaining any garden inside or out, requires a certain amount of maintenance. Involving family, friends or neighbors in the greenhouse garden is a fantastic way to distribute tasks, bring people together and “share the wealth” of your homegrown food.Many of the daily greenhouse tasks such as watering, venting, lighting, and fan control may be automated to give owners more independence and ease.
What is Your Budget?
Of course, everybody would love to have an unlimited budget to build the grooviest greenhouse around, but rarely is this the case. A $5,000 budget or less will allow for a more basic structure like a hoop house or small prefab polycarbonate unit. These are typically used as season extenders, unless you live in a milder climate.
If you live in a harsher climate, such as the mountains or the northern part of the country where access to fresh organic fruits and vegetables is bleak, especially in winter, a more substantial investment will be needed to grow year-round. A good starting price for a highly energy efficient four-season greenhouse is $20,000. If your budget is more, you have the options of investing in a larger greenhouse or automating the systems within the greenhouse.
