I have been wondering about the lighting issue for sometime now, and what I have been wondering is : If I go to Home Depot and purchase a 400W HID fixture, and one 400W HID
bulbs (for around $25). Will this be the "correct" HID bulb for plant growth? Or is this bulb only suitable for illuminating parking lots? The same question posed except for
hps lights.
Thanks a few hundred (Inflation, you know!)
