Growing plants within a residence, building, conservatory, or in a greenhouse is called indoor gardening. Sometimes incorporated as part of air conditioning or heating systems, these gardens are also useful for ornamental purposes and great space savers.
The idea of indoor gardens originated in Rome. The Roman emperor Tiberius was fond of a cucumber like vegetable. Catering to the king, the Roman gardeners used artificial methods (similar to the greenhouse system) of grow it round about the year.
Italy is known as a pioneer of the first modern indoor garden in the 13th century. Exotic plants brought by explorers from tropics were stored in botanical gardens. The revolutionary concept of greenhouses spread from Netherlands to England. Providing adequate and balanced heat is a challenge, but Netherlands has succeeded in leading the produce of millions of vegetables every year.
Decide on the type of indoor garden you desire, grow room or grow box. Take into consideration garden area, weather for growing clones. Do you want a vegetative stage or flowering; select your light depending on these factors. Measure garden grow area to calculate where to set up your fan exhaust.
An oscillating fan controls temperature, humidity, and degree the CO2 levels while improving air circulation. Every indoor garden design should have both oscillating fan and air exhaust. An indoor/outdoor thermometer will monitor and control the temperature in your garden. A charcoal filter might not be a bad idea, but the exhaust fan will need to be a centrifugal fan. A squirrel cage fan is not strong or suitable for an indoor garden.
Indoor gardens have their own unique requirements. Pests and diseases have to be kept in check, while extremes of heat and humidity have to be in control. Irrigation and water supply has to be pre-planned. Significant inputs of heat and light have to be maintained for warm-weather vegetables. Inside temperature and humidity can be monitored through a wireless sensor network. Data gathered can be transmitted to a control location useful for productive control heating, cooling, and irrigation systems.
