does it matter how long grow lights are

[ladyslipper]

thanks for your replies guys, could I make up for the fact the light drops off at the end of the grow tubes, if I had the stand about 3 ft from an east window that has no shading?
regards, m

Sure could. A lot of folks keep their racks near/in front windows for additional light. Many times its almost necessary since fluorescents dont give off real intense light. If its unshaded, then the several hours of sunlight coming in each (sunny) day will do great for them.
