When it comes to grow lights professional nursery managers prefer metal halide grow lights. The color spectrum this type of bulb generates is intense and when paired with high pressure sodium bulbs is considered ideal for growing plants of every designation of light needs. Cost, positioning and monitoring are all greater than the demands of metal halide grow lights are greater than fluorescent systems but are needed if you are planning to grow vegetables, fruit bearing or flowering plants indoors.
Due to the heat generated from the bulbs it is important to keep the bulbs between a foot and foot and a half from the plants. Many indoor growing environments are setup to help keep the distance between lighting and plant tops at the optimal span. Some place risers of wood or block beneath the surface that the plant container sits on and remove the risers as the plant grows. Approaching the solution from the opposite angle, some growers mount the metal halide grow lights on frames that are hung from the ceiling and can be raised as the plants mature. Since distance can be somewhat variable it is important to recognize the signs of light stressed out plants. Yellowing or brown leaves indicate that the distance between the plants and lamps needs to be increased as the plant is getting burnt from the heat generated by the light bulbs. On the other hand if the plant is stretching out and getting leggy the light bank needs to be moved closer. Catching these tell tale signs early is the secret to good indoor gardening.
Use of timers to insure the plants get the right amount of sunlight can make indoor gardening much easier. Plant light needs are designated as full sun, partial shade, shade, and deep shade. Those needs are the basis of how long the metal halide grow lights need to be on per day. Set the timer and then watch the plants for indications of what they need. The time frames listed to simulate natural sunshine are estimates. You need to monitor the plants themselves to fine tune the amount of time the lights are on and off.
A few small accessories are good to have in combination with metal halide grow lights. Since the environment also includes work with water a surge protector is a wise piece of equipment to have your metal halide grow lights in to. A small fan is the other recommended piece of equipment that helps create a good growing environment. Circulating air disperses the heat as well as discourages the growth of mold.
Metal halide grow lights provide the type and amount of light needed to grow plants to maturity indoors. Blooming and fruiting vegetation are huge consumers of red spectrum light that can be generated by metal halide grow lights. Although setting up a growing environment equipped with a combination of metal halide and high pressure sodium lights is more costly it makes it possible to grow plants designated as needing full sun or partial shade indoors.
