Linda, I have to rotate my trays anyway, because the outside row of seedlings in my set up gets less light than the inner rows. So when I pull out my tray to reverse it, half of it comes out from under the lights and can be watered. Then I shove that to the new position and pull out the dry side and water that and replace under the lights. I've never cared for bottom watering either. I also use a fan after most of the seedlings are up.
