Grow Light Systems

FAQs:
Q. What is T5 Fluorescent Grow Light Fixture?
A. The T5 fixture use high sufficiency, digital electronic ballast, built into unit, to power the T5 fluorescent lamps. The fixtures have a low profile and give off low heat, allowing the fixture to be placed close to the tops of the plants. The large grow area of light dispersal and intense light makes the T5 very comparable to the light output of the Metal Halide or High Pressure Sodium systems.
Q. Why use Metal Halides for vegetative growth and High Pressure Sodium for flowering?
A. Many people switch between bulbs for different stages of growth for a couple of reasons. First of all, Sodium bulbs have been known to make some plants grow leggy and stretched out because of the yellow to red spectrum that they give off. Metal Halides tend to keep these plants tighter with less space between inter nodes. So some growers use the Metal Halide lights during vegetative growth to keep the structural growth of the plant nice and tight. But they switch to Sodium lights when the plants begin to flower because the Sodium lights produce so much more light than the Halides. Even though the Sodium's do not have as good a spectrum as the Halides the intense light that is put off by the Sodium's aids in flower development and fruit set. Do not be fooled though, you can use either light throughout the life of a plant and get excellent results.
