We use old fashioned fluorescents and 4' trays about 20-22 inches wide
with 4 tubes. Like many we use egg-crate* for drainage. We upgraded
today by setting 1/2 inch spacers under the egg-crate(legs) and window
screen on top. It is not as easy to set your plants in place - the
window screen floats like a table cloth and moves as freely if you
drag a pot. But now when the bark falls into the tray it will be on
top of the window screen and I will be able to clean it off. It will
not get into the egg-crate or into the drain on the tray. We cut the
legs from left over PVC pipe we had on hand so they happen to be about
1 inch diameter. They would probably be better if they were larger -
but scrap is the correct price..... free.

Ya - late in the game for the light bulb to go off -- but better late
than never.

* egg-crate = the plastic diffusers used in commercial buildings on
drop ceiling fluorescent fixtures, about 4' x 20" they have a pattern
of small squares.
