Tips to Build a Greenhouse

A greenhouse is a building structure, especially constructed to grow or cultivate plants in controlled conditions of light, temperature, ventilation and humidity. Exotic plants, orchids, flowers, vegetables and fruits are planted in greenhouse for the healthy plant growth and/or maximum yield. Specific crops and salad vegetables can also be grown for commercial production all the year round, irrespective of the off-seasons. In addition to regulated environmental conditions, the spread of plant diseases as well as pests are controlled in greenhouse. Considering these advantages, many hobbyists and gardeners opt for growing plants in greenhouses.

How to Build a Greenhouse

Like other construction works, the first step in building a greenhouse is to decide the correct location. Based on the climatic conditions, you can select a proper site that receives maximum sunlight. If possible, build the greenhouse in the south or southeast to the house, otherwise you can orient in the west or southwest direction. For cold areas, the greenhouse should be insulated or installed with heating equipment in order to retain maximum temperature inside the greenhouse.

Another factor to be considered about the site is a good drainage system. You can create a raised base, so as to prevent draining of rainwater inside the greenhouse. Once you have confirmed the location of greenhouse with the necessary features, you can purchase the structural requirements for building a greenhouse such as frames, coverings, foundation and flooring materials.

Greenhouse frames are available in various shapes such as gothic, quonset (circular frame), A-shaped and rigid frame (vertical sidewalls with a slopping roof). While speaking about the coverings of greenhouses, glass and fiberglass are the most durable materials that provide maximum warmth and humidity. Fiberglass is flexible and can be used in straight or curved surfaces. In case of a low budget project, you can opt for plastic coverings.

The foundation of greenhouse depends on the weight of the coverings; permanent foundation is recommended for glass materials. Another option for lightweight coverings is fixing with the help of railroad ties. Regarding flooring option, permanent flooring is not preferred as it remains wet for a prolonged duration. Creating a concrete walkway with gravel floor is the best option for greenhouses.

All types of greenhouses require ventilation, air circulation, water irrigation, humidity regulation and pest control. For providing ventilation, simple windows can be created at a specific height of the greenhouse. Small fans can be used for the air circulation purposes; depending on the size of greenhouse, you may need to fix several fans. Regarding irrigation system, you can fix automatic watering systems. After completion of making all these arrangements, you can place plant racks at a particular places inside the greenhouse for keeping container plants.

If there is an extra space, you can attach a small room for storing fertilizers, organic manures and other gardening tools. Building a greenhouse on your own is quite a rewarding task. You will really feel satisfied after you start growing plants in your greenhouse. Irrespective of the climate and outside environmental conditions, you can harvest your favorite vegetables or enjoy the beauty of flowers. One word of advice for growing plants in greenhouse is to isolate any diseased plant, as it can spread easily to the other neighboring plants.
