This means that each plant uses not only a smaller vertical space, but has a smaller radius. Plants which are flowered when they are very small can be placed very close together. Short plants use much less vertical space so gardeners often find it convenient to divide the growing area into several levels of shelves or bunks. Setting up and maintaining a successlul indoor garden requires a bit of work and some hands-on experience. No one gets the garden running at full potential the first time out.
Small gardens are easier to maintain than large ones.
They take less time, but more importantly, they do not have the problems of energy consumption, ventilation and heat that large gardens have. With a small system, the energy consumption does not go up that much. A large system using several large wattage lamps spins the meter. The heat created in a small system is easily dissipated into the surrounding environment, especially during cool months. A large system requires a more sophisticated heat-exchange system.
