What kind of bulbs are usually used for the vegetative growth phase?
Specifically, The blue light, ranging from 400 – 490 nanometers, is used during the vegetative and foliage growth phase. The orange-red light, between 590 – 700 nanometers, is used during the flowering and fruiting phase.
Can you use metal halide for veg?
Metal Halide (MH) lamps typically emit a white colored light. Traditionally Metal Halide lamps have been used by indoor growers during the vegetative stage of plant growth. They are ideal for growing plants up to the flowering and fruit production stages because they mimic the spring/early summer seasonal sun.
How far should metal halide lights be from plants?
As with the HPS & MH light, you should conduct a hand test to see how hot the light is. Once you have done that you can estimate the distance needed between plant and light, however, typically you should hang a CMH bulb two feet above the canopy of your plants.
What is a metal halide bulb used for?
Metal-halide lamps are used for general lighting purposes both indoors and outdoors, such as commercial, industrial, and public spaces, parking lots, sports arenas, factories, and retail stores, as well as residential security lighting; automotive and specialty applications are further fields of usage.
Are LED grow lights as good as metal halide?
LEDs tend to last much longer and are a more energy efficient and less maintenance intensive technology. Metal halides have long warm-up periods and a shorter lifespan but produce a very high quality light and are one of the most efficient lights when it comes to very cool color temperature outputs.
Can you touch a metal halide bulb?
You should be extremely careful never to get skin oils or anything else on a small MH lamp (the small ones are around the size of a fingertip or so). This will definitely harm the lamp and can cause premature failure.
What light do you use for vegging?
T5 Fluorescents One technology that revolutionized lighting for indoor vegetative growth is the T5 fluorescent. T5 fluorescent lights are high-output fluorescents and are capable of producing great vegetative growth. Some old-school growers may remember using T12 or T8 fluorescents for growing plants.
What color light is best for vegetative growth?
Blue light
Blue light is necessary for vegetative growth while red light is needed to promote flowering and fruit production. The color temperature of a grow light helps you understand if the overall output of the grow light trends towards blue or red.
