Ken -
As long as the peat pots are spaced pretty far from each other and not too much "over-crowding" , watering from the bottom has never been easier ~
Also, I always use room temp. 24-48 hour distilled water ; and that rooms usually about 70 degrees F ... (South facing window ect.)
Using this method , I usually have tomato seeds up in 4-7 days; pepper seeds in 10; and herb seeds in 2 ...
Dwarf project seeds however, are on their own schedule ~

ps.
been using those trays for 4 seasons - washed of course with diluted bleach ...
