Incandescent grow lights are cheapest but require utmost care
Incandescent lights are least expensive and you can buy them for around $30 to $40. These lights need to be placed at least 24 to 25 inches away from the vegetable plant you are growing. Since these lights produce a lot of heat, you need to be very careful about their placement. There are two apparent advantages of these lights. First of all they are pretty inexpensive. Due to the affordability they are used widely. Secondly they are very easy to install. They can be very easily placed right at the spot above the plant where they are needed.
Fluorescent Grow Lights are the most favorite choice for indoor vegetable farmingThese lights are the most popular ones among those who grow vegetables indoors. They are very popular for many reasons. They are highly energy efficient. They can produce thrice as much light as incandescent lights consuming the same amount of energy. Although a little costlier than incandescent lights, they are still relatively inexpensive. Especially when you consider their longevity, they prove to be much cost effective. A fluorescent grow light bulb can last for more than 20,000 hours, which is over 2 years. This light produces more blue light and hence it is especially effective for the growth of the seeds. Fluorescent light does not produce any heat and hence it can be placed directly above the seeds.
Full spectrum fluorescent light is nearly as good as sunlight
Even if you are growing vegetables indoors, it is highly recommended that the plants are exposed to natural sunlight for at least 12 to 14 hours in a day. Sunlight offers full spectrum which is vital for the growth of the vegetables.
Full spectrum lights are not the replacement for sunlight but they can be used when sunlight is not available. The red light of the spectrum is needed for the blooming. Therefore the combination of blue and red light ensures maximum growth.
LED grow light is perhaps the future
LED lights are the most advanced grow lights. The primary advantage of these lights is the small size and weight. They are extremely easy to install and can be used just about anywhere. They have a perfect combination of red and blue lights for the optimized growth of the plants.There are many types of grow lights available to grow your own vegetables. Your choice largely depends upon the kind of vegetable you are growing and your budget. Most of the non-commercial growers have wide variety of vegetables at one place. For them fluorescent grow light could be the best option as it offers full spectrum and is relatively cost effective.
