I did my change over with time rather than height. I had my pc's on for 12 hours. When I put the mh on I started at 6 hours and moved it up to 8 hours by about 1/2 hour a week. I know that other people use layers of screen and take a layer away each week. I had all kinds of crazy algae growth when I changed lights so be prepared.
