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.

The Gardener's Dream: Moisture And Temperature Sensors For Your Greenhouse


Having a greenhouse is every gardener's dream. However, unless you live in a large house that is surrounded by a large green area where you can build your own greenhouse odds are that your only chances of enjoying one is when you visit the plant seller.

Greenhouses provide the perfect environment to grow different kinds of plants and flowers, especially the most delicate ones that require specific levels of humidity in order to grow properly and are extremely sensitive to drastic changes in temperature. Some greenhouses are very large and others are smaller, but they all have that distinctive atmosphere and smell that invite us to travel, at least with our minds, to foreign tropical forests.

If you are lucky enough to have a glass building you can turn into a greenhouse, you will find this article particularly useful as we will discuss two gadgets that will make it really easy for you to keep the temperature and humidity in the environment within perfect levels: a moisture sensor and a temperature analyzer.

Moisture sensors are also popularly referred to as humidity analyzers or hygrometers. They are extremely sensitive and technical devices that allow professional and amateur gardeners to ensure that the plants and flowers that they keep in their greenhouse are in an environment that provides them exactly with the humidity they require. These instruments are really accurate and they can be adjusted to the needs of a particular plant species. It is even possible to connect the moisture analyzer to the irrigation system so that plants only receive water when they need it and therefore they are not exposed to unnecessary watering.

Professional greenhouses usually have more than one humidity analyzer and the gardener monitors the different devices from a central computer and makes automatically all the necessary adjustments.

Temperature sensors or analyzers are thermometers that help professional and amateur gardeners be sure that the plants that they have growing in their greenhouse are kept under the correct temperature. As you probably are well aware of, seeds and plants are extremely sensitive to temperature changes and they grow healthier and better if they are not exposed to drastic changes in temperature. In addition, some tropical plants need certain temperatures in order not to wither and even a drop of a few degrees can make them wither.

You can buy your moisture and temperature sensor over the Internet or in shops devoted to professional gardening.

Sensing Inside a Greenhouse Through Wireless Sensor Networks - An Emerging Technology


What is a Wireless Sensor Network?

A Wireless Sensor Network (WSN) consists of several distributed wireless sensor nodes that sense vibration, noise, and temperature. Each node has its own memory, battery, a processor and a sensor and is autonomous. These nodes are reliable, heterogeneous, scalable, fault tolerant and they require less power consumption.

In today's world WSN are used everywhere say in traffic controlling systems, in forests to detect fire, in green houses to monitor plants, in military to monitor spy activities, in houses to monitor water and waste water, in smart houses and in many more places. WSN has become an essential technology to live with.

WSN in Greenhouse monitoring:

A greenhouse is a place where plants are grown. To set up WSN in a greenhouse the nodes are placed on leaves and crops. The base node is responsible for collecting data from all nodes and communicating with the main server or computer.

For whom?

WSN for greenhouse monitoring is required for the greenhouse owner who wants maximum cultivation of crops in any environmental conditions.

The WSN nodes sense following:


Temperature
Level of Carbon Dioxide
Light
Humidity
Radiation

Monitoring these environmental factors continuously helps to gather information about the crops and plants in the greenhouse. Information collected is further manipulated to manage productivity of crops. Whenever there is a change rather than expected, i.e. temperature increase or decreases suddenly, the manager is notified about the condition of affected area using text message, or call or e-mail or any other thing like buzzer by the data communication system. Manager then takes action accordingly.

WSN nodes communicate with each other and share important data that will be useful for network. Network topology used for such networks depends on total area of the greenhouse, cost and other factors.

Data stored using sensor nodes on the computer is then manipulated and meaningful interpretation is obtained using data mining, knowledge management methods.

It provides faster deployment, installment flexibility for sensors, and better sturdiness than wired networks.

Conclusion:

A Wireless Sensor Network is a measurement tool. WSN applied in greenhouse evaluates and maintains growth of crops. It saves cost and energy of wiring and connecting all nodes. It only costs to set up and maintain the network. It is very convenient to handle greenhouse in real-time more efficiently. It is better to use such technology rather than wasting money in poor estimations and labor that is typical faced during crop cultivation.

Controlling a Greenhouse Environment


Once you have put up your greenhouse, it is time to make it do what it was intended to do - foster the rapid and healthy growth of the plants inside it. The strength of a greenhouse lies in the ability to control the climactic conditions inside.

One such significant climactic condition is temperature. You need to have the right temperature if you are to realize optimal plant growth. Light is another important consideration. Note that one climactic factor may have an impact on another. For instance, too much sunlight inside the greenhouse can raise the indoor temperature beyond the appropriate levels.

There are a number of actions you can take to manage the impact of external weather changes to the greenhouse's internal atmospheric conditions.

a. Ventilation - Every greenhouse should be built with two forms of ventilation in mind - natural and artificial ventilation. For natural ventilation, you need only appropriately position a number of outlets and inlets to allow the natural flow of air in and out of the greenhouse. Electricity may or may not be used but this would only be for controlling opening and closing the inlets or outlets. While natural ventilation is a great cost saver, it is ineffective in locations with high outdoor temperatures.

And this is where automatic ventilation comes in. Auto-ventilation regulates indoor temperatures using electricity powered louvers and exhaust fans. The difference between automatic ventilation and electricity-powered natural ventilation is that the former is usually part of a larger air conditioning system that detects temperature and powers the louvers and fans accordingly.

b. Cooling - When ventilation alone is inadequate to manage the temperature within the greenhouse, a different approach is required. Two common strategies used to control temperature and that can augment ventilation are: fog systems and pad-and-fan systems.

Fog systems use nozzles installed every 50 to 100 feet in the greenhouse to evenly distribute a cooling 'fog'. It is expensive because clean water must be used to prevent the tiny mouth of each nozzle from getting blocked.

Pad-and-fan technology goes hand in hand with automatic ventilation. Evaporative pads are installed at air inlets and cool the air entering the greenhouse. The cool air circulates within the greenhouse picking heat in the process before it is pulled out via the exhaust fans.

c. Humidity - Humidity must be kept in check to prevent plants from succumbing to disease. High moisture content in greenhouse air increases the amount of condensation on plants thus hampering respiration. High humidity is also a breeding ground for pests and fungal plant diseases. To better manage humidity, the vapour pressure deficit (VPD) must be measured regularly and maintained at the optimum level of 0 to 1 psi. VPD is a calculation of atmospheric humidity versus the humidity at which water condensation will start.

d. Shading - Shading is a means of temperature and light control that uses automatically operated shades or blinders. The shades close when there is too much sunlight during the day or if warm temperature needs to be retained in the greenhouse at night. A sensor detects internal temperature and triggers the shades' opening or closing.
