One of the most important things to bear in mind when growing plants indoors is that plants need sun, not just light, in order to thrive. They need radiation at various wave lengths. It may not be sufficient to place plants by a window.
Unlike a traditional light bulb for home use, indoor growth lights mimic the spectrum of the sunlight. There are several types, from fluorescent lights to HID (high intensity discharge) lights, LED lights and metal halide bulbs. Each needs to weigh its advantages and disadvantages. Have a look at buy indoor grow lights for more info on this.
The fluorescent lights are the cheapest and easiest to use of the indoor growth lights, but they have to be hung near to the plants. HID lights are relatively small units that generate powerful light, but they require a ballast to regulate the amount of energy that goes to the lamps or other HID lights that are high-pressure sodium bulbs. Without leaving sticky fingerprints on them, the bulbs themselves have to be treated with caution, which may focus the light and cause the bulb to burst. The HID indoor growth lights can rely heavily on your electric bill, so a reflector might be needed to make it cheaper and more useful.
You can do a few things by using a reflector (a reflective surface that bounces the rays); the light source can be farther away, because you get the light from the lamp and from the reflector, you can use less bulbs. For reflectors with cooling systems, light reflectors come in several shapes and sizes and cost from $40 to over $300 for reflectors that minimize the need to cool the area when the indoor lights are mounted in a closed area.
Indoor LED lighting is highly effective and burns at much lower temperatures. They are more costly than the others, but without having to use a cooling system, they are paid back. The lights only use 20 percent -30 percent of the energy used by the other systems. That will decrease the energy bill costs. Since they fit into standard house sockets and last up to 10 years, they do not need any specific modification. There are 3 different types of indoor LED growth lamps, each of which, depending on your increasing needs, offers different sections of the light spectrum. Bulbs will each cost about $100.
