Grow lamps are vitally important in the world of hydroponics as without them, plants wouldn’t be able to grow. They provide the electromagnetic spectrum appropriate for photosynthesis that stimulates plant growth. This is all very crucial to the growth of the plant as the light produced from the grow lamp is very similar to that of the sun.
There are a number of different types of grow lamps available to use for you hydroponic needs, I shall be focusing on the following three. First are incandescent grow Lights. These grow lamps have an average life span of 750 hours; they are generally less energy efficient than fluorescent or high-intensity discharge lamps. This is because it converts much of the electricity consumed into heat and not light. They have a red-yellowish tone and low color temperature. In addition to this this type of grow light can attract unwanted attention from pests due to the illumination given by the light.
The second is fluorescent grow lights. These indoor grow lamps are generally used for growing vegetables or for starting seedlings. They are very much suited to this as they are available in any color temperature in the range from 2800 K to 6000 K. Compared to Incandescent grow lamps they have a much longer life span (20,000 hours) and they produce twice as many lumens per watt of energy consumed. High Output Fluorescent Lamps are available with a slightly shorter life span (10,000 hours) but producing twice as much light.
And the last is high pressure sodium lamps. There are clear advantages and disadvantages to these grow lamps. The advantages are if used for vegetative phase, plants will usually grow slightly more quickly. And in the horticultural industry they enhance the fruiting and flowering process in parts. Disadvantages are if used exclusively throughout a plants growth process the plant tends to be taller and leggier with a longer length. And they do not appear very healthy (even though they are) due to the poor color rendering of high pressure sodium.Led grow light for cactus,гроубоксы своими руками из холодильника
