It is KILLING me to watch people grow and keep their lights so far away from their plants.

If you are going to invest the time, money, effort, and risk into growing YOU should definitley keep your HID lights as close to the tops of your plants as possible. This means, you will need adequate airflow. Exhaust lights and keep oscilating fan between the tops of the plants and the bulbs.

I have been visiting a few garden in Northern California latley and the growers have their lights 16-24 inches from the tops of their plants..

WRONG, BAD, a waste of F-ing light. With proper airflow a 1000watt bulb with a glass fixture can be brought within 1- 4 inches of your plants...

This will more than double the yield of a light at 16-24 inches... not to mention make some huge baseball bat diameter colas..

IMPORTANT - bring light down slowly- start at 16 inches and lower light 1-2 inches per day... study leaves..... plants less than 3 weeks old probably can not handle a 1000watt bulb at 2 inches.
