I think it's an interesting idea but impractical for cfls IMO. If you had multiple different spectrum hid lighting setups and used that instead of cfls, it'd be a more useful experiment. Since cfl lumens drop significantly beyond say an inch away from the bulb, I wouldn't expect any useful information to come from it.

Balkey Reviewed by Balkey on . MH/HPS + CFL lighting sequence I've got some extra lights (6x 6500k 26 watt, 4x 2700k 23 watt cfls plugged into four Y-fixtured clamp lights) accompanying a 250 watt MH/HPS bulbs/Lumatek digital ballast between two timers. I have 6.75 sq ft space potentially giving my "to be" garden 5000+ lumens per sq foot. I plan on raising at the most 8 square pots in a 1.5'd x 4.5'w x 6'h closet. With all this extra lumens per sq available for the plants, I have an idea or out of curiosity to imitate a natural phased light Rating: 5
