BTW, I found that laying down a pad of cotton flannel in the bottom of a seedling tray helps pull excess water out of the tray. I think this helps most in shallow cells or pots, where water-logging the bottom inch of soil wastes half of the root zone.
The cotton flannel also makes sure that every pot or cell has access to water even if you only put a few ounces of water into the tray. That makes bottom-watering really easy.
I still use the baster to remove any water that is deeper than the flannel is thick.
