Indoor gardening is one of the most relaxing hobbies you can pick up. No indoor garden is complete without its good and efficient grow light systems. Often times, the quality of the light bulb and light movers is the different between an average garden and one which is thriving.
There are a number of different grow light systems you can choose from. Incandescent, fluorescent and high-intensity discharge bulbs each have their very own benefits. Your choice of light systems and grow light movers is ultimately determined by the type of plants you are growing and where your indoor garden is located.
Incandescent Bulbs - You'll quickly recognize incandescent bulbs since most household bulbs are this type. They are a decent source of red light, but a poor source for blue. When combined with the use of good grow light movers, they are capable of producing some heat in relation to the amount of light they give off. However, the plants can be burned if they are placed to close to the bulb even with a grow light mover.
HID Lamps -These lamps are commonly used by commercial growers and serious horticulturists. HID lamps combined with a grow light mover emit twice the amount of light as an incandescent or fluorescent bulb while using the same amount of energy. It's is because they so energy-efficient that you'll often see HIDs used to light shopping malls, baseball fields, and streets. The special fixtures, light movers and bulbs used in HID lighting are much more expensive compared to incandescent or fluorescent lights, however.
Fluorescent Bulbs - Here we have bulbs which can produce two to three times more light than incandescent bulbs while using the same amount of energy. They are the most inexpensive lights for indoor gardening and are perfect in conjunction with a hydroponic light mover. The color of light is determined by the phosphor coating on the bulbs inside.
Cool white bulbs with light movers are a great source of blue and yellow-green light. You'll find these employed as interior lighting in schools and office buildings. Plants grown under cool white bulbs with grow light movers end up stocky and sometimes slightly stunted.
Warm white bulbs using a grow light mover emit a good amount of orange and red light, but not as much blue and green light. These are a good choice for the gardener looking to grow seedlings under 2-bulb fluorescent fixtures combined with a hydroponic light mover. You can achieve a good color balance by combining a cool white bulb, a warm white bulb, and grow light movers.
Full-spectrum fluorescent bulbs give off a balance of cool and warm light. It's the closest light you can produce that replicates the natural solar spectrum. These bulbs are excellent for seedlings if you use light movers. I recommend using them as well for everyday houseplants or culinary herbs too.
