Greenhouse Gardening For Food and Fun


Greenhouse gardening is the way to grow plants that are not suited to your climate, or just start your gardening earlier. Whatever shape or size you choose for your building, you create a separate little ecosystem within it. Everything that happens in the green house affects all the plants because you are working in an enclosed space, therefore it is a more intense way of gardening.

Kits and complete greenhouses are plentiful, from a wide variety of suppliers. Gardening supply businesses, lumber yards, hardware stores, and most large chain stores have stock available. If you are so inclined, there is much to be said for building your own greenhouse. An idea to simplify the task of this do-it-yourself project, is to buy the frame only, of a garden shed package, Doing this saves having to cut all the angles involved in building your own rafters and framing a doorway, speeding the process up. From there, you can use your own materials such as windows you have collected, and design your ventilation options according to your own preferences.

The ecosystem in the greenhouse is created with the usual components of gardening, soil, water, sunshine, and fresh air. Soil needs to be fibre rich so the seeds or seedlings can set roots easily. Well-rotted manure is a good base to start with if it is available. You will have to water everything regularly, whether it rains or not.

Fresh air, or air circulation, in the greenhouse, is very important to your gardening, and can be provided in two ways. If you can situate the greenhouse to take advantage of natural winds, and have adequate openings for ventilation, the air circulation may be adequate. Ventilation will improve with the use of one or more fans in the greenhouse. Your gardening experience will not be very successful if the temperature and humidity are allowed to spike throughout the hot days of summer. They need to be monitored so you know what is happening. Temperature and humidity can be supervised with a relatively inexpensive monitoring system that allows a sensor in the greenhouse to transmit to a receiver in your house. This system also allows you to know when your gardening efforts of the season will begin to need frost protection. A small heater with a fan, or the fan you have already been using with a heat source of some type, will do the job.

One word of caution regarding the use of any chemicals in the greenhouse: be very careful. All the plants will be affected by any chemical used because they are enclosed. This issue provides all the more reason to practice organic gardening and not use any chemicals.

Greenhouse gardening is a good way to experiment with plants that are not native to your climate. Because you control the environment, you can grow most anything you want.
