Plant Grow Lights
Plant grow lights come in many shapes and sizes. High Intensity Discharge (HID) lighting produces the excellent usable light for indoor gardening. High intensity bulbs come in a variety of color spectrum's. to Generally blue spectrum light is used for vegetative growth for flowering plants and none flowering plants. Plant grow bulbs that produce a blue spectrum are Metal Halide with a 6K temperature. High pressure sodium bulbs produce a red spectrum light with a temperature of 3K used for flowering plants.
Fluorescent lighting runs cooler than HID which allows the bulb to be very close to the plants. However, Fluorescent plant grow lights do not have enough intensity to light beyond 12 to 18 inches. Fluorescent grow lights are available with a vegetative or flowering spectrum.
