Tips & Tactics

Helpful advice for making the most of this Guide

• •  Check to see if the greenhouse manufacturer that you buy from offers workshops.

Greenhouse manufacturers strive to continually add new products to their lines. The variety of greenhouses include indoor greenhouses, mini greenhouses, residential greenhouses and greenhouse kits. In addition, some greenhouse builders offer custom greenhouses for sale that match your home or business architecture.

The cost of the greenhouse depends on the frame, the size, the type of paneling and the extra features you chose, which include ventilation systems, heating options, glass paneling or plastic sheets and different dimensions ranging from a small 8-foot by 8-foot shelter to large 9-foot by 24-foot structures.

Before you shop greenhouses for sale:

1. Decide the purpose for the greenhouse.
2. Know the type of plants you want to grow.
3. Understand which greenhouses are right for your grow zone.

Determine the location for the greenhouse

Normally you want to choose a sunny area for your greenhouse, but greenhouses used for starting seeds or nurturing seedlings require more shade. If you pick an area close to a structure like a house or near trees, keep in mind that shadows change location based on the time of year.

I recommend: Find out more about choosing a location from Envirocept, which provides information on optimizing sunlight through the use of location. The site also discusses finding a level area and suggests fixes for uneven areas.

Decide the type of frame you need

A greenhouse manufacturer may sell a variety of frames or offer simple plastic frames only. The type of frame you need depends on your grow zone, the weather and personal taste. Galvanized steel and wood frames support glass paneling as well as hold up in harsh or heavy weather like snow. PVC and aluminum framing assemble with ease, cost less and provide a basic frame for mild climates.

I recommend: Buy from a greenhouse manufacturer that offers a selection like Greenhouses.com. Browse the metal frame, wood frame or plastic frame categories to find the best framing option. The site is competitively priced.

Be cautious when buying greenhouse kits wholesale

Some companies advertise greenhouse kits wholesale but charge just as much or more than other companies with greenhouses for sale. Always compare rates, and if you find a better rate, ask the wholesaler to lower their price.

I recommend: Compare wholesale prices at Farm Wholesale, which offers wholesale kits as well as other styles of greenhouses.

Whether you plan to construct a greenhouse for personal use orgrow plants and crops to sell, understanding some key terms that apply to greenhouses is a good idea. Greenhouses come in many shapes and sizes, but all require adequate growing conditions for plants.The proper fertilizer, along with good ventilation and heating systems, will yield better plants. Before building or purchasing a greenhouse, learn the important key terms and how they apply to your greenhouse-growing ambitions.

Drip irrigation

Drip irrigation is a way of automatically watering your greenhouse plants. This type of watering system waters the soil, not the leaves, and allows you to adjust the amount of water your plants get and when they get it.

I recommend: Northern Garden Supply shows pictures of drip irrigation systems and explains the benefits of outfitting your greenhouse with this type of system.

Insect screens

Greenhouse plants benefit from proper ventilation and fresh air, but can be harmed by insects. Insect screens made for greenhouses offer enough airflow for healthy plants, but filter out harmful insects.

I recommend: Ecologic Technologies offers technical information about insect screens and also gives an outline for proper installation of insect screens.

Mechanical ventilation

While screens and natural airflow benefit greenhouses, mechanical ventilation is also necessary to create an optimum growing environment. Proper installation of fans and thermostats can help control temperatures during winter and summer months.

I recommend: The National Greenhouse Manufacturers Association gives a detailed description of different mechanical ventilation systems and suggestions on how to install them.

Hydroponics

Hydroponics is used in many greenhouses as an alternate way to grow plants. Instead of using the traditional method of growing in soil, hydroponics uses nutrient-enriched water solutions to grow plants.

I recommend: How-To Hydroponics gives a detailed description of hydroponics and the benefits of using this method.

Fertilizer

As most gardeners know, different plants require different types of soil and fertilizers. Knowing the proper fertilization methods for different plants in your greenhouse will help you grow healthy, bountiful plants.

I recommend: Virginia Tech analyzes basic greenhouse fertilizer information and also offers calculations for mixing up stock solutions.

Aquaculture and aquaponic systems

Aquaculture and aquaponic systems go hand in hand. Aquaculture is basically the farming of fish, and aquaponics is a form of hydroponics connected to an aquaculture setup. The fish waste sends nutrients to the plants, and the plants clean the water sent back to the fish.

I recommend: CropKing gives detailed definitions of aquaculture and aquaponics. It also has photographs of working aquaponics systems.

Greenhouses provide a secure location for growing all varieties of plants. The enclosed structure of greenhouses protects plants and flowers from any wind, weather or other outside damage while maintaining a controlled climate to foster growth. Whether you want indoor greenhouses, small greenhouses or even residential greenhouses for a home-based business, be sure to pick greenhouse kits wholesale with the right framing, flooring, plastic or glass insulation. Other tools for greenhouses installation and maintenance should also be suitable for feeding your plants and providing good drainage and ventilation.

Site location is among the many factors to consider for greenhouses installation and maintenance. Greenhouses for sale can be 8 feet by 8 inches, 12 feet by 12 inches or other dimensions depending on the backyard or field space. Growing zone also plays a role in greenhouse installation, and options such as glass and plastic siding and roofing may be suitable for absorbing sunlight, and hot and cool temperatures to cultivate plants and flowers. Other considerations for greenhouses installation and maintenance include:

1. Researching greenhouse manufacturer site choices and design ideas.

2. Finding publications on greenhouses installation and related building materials.

3. Getting maintenance tips, such as keeping greenhouses clean and properly ventilated.
