No, to the question of standing water.  Its okay to water them by setting them
into trays of water for water take-up or if you have to go away for a week.
Otherwise, the roots will grow like mad through the tray of water and you'll
have to cut them off to get the plant out of its pot.    I clip mine off at
10" also, don't raise the lights....cool white bulbs only (warm white and gro-
lux are to help bloom), lights on 24 hours a day.  My table is 4ft x 8ft
plywood and my 8, 8ft tube fixtures are attached to 4ft x 8ft plywood attached
to the ceiling by chains.   I can get about 1700 seedlings under there.  I've
learned not to germinate the seeds much before Feb 1 (for line out June 1),
otherwise too much mowing and at least every other day watering by April !
