These are the same powerful lights used by professional
greenhouse growers. HID lights are highly energy efficient. You can grow
any plant, anywhere, anytime you choose. The high intensity
light energy is effective much farther than fluorescent:
250 watt/3 ft., 400 watt/5 ft., 600 watt/6 ft. The 400
watt is recommended for most hobby greenhouse applications.
- High Pressures Sodium (HPS)
This light has extra output in the yellow, orange and red spectrum,
which increases flower quality, size and fruiting. It is the best choice
for use in a greenhouse.
- Metal Halide (MH)
A full light spectrum is the advantage of MH. It is the most effective
light for use indoors where there is limited sunlight.
