Fluorescents will work well, incandescent won't. You don't need the special
"grow" bulbs; a combination of one warm and one cool bulb is good, and you
can put them in a regular shop light. Keep the lights very close to the
plants--just a few inches above them. Don't leave them on 24/7. They need
a rest period--shoot for 16 on, 8 off. The cool temps will be ok once they
seeds have sprouted, but both tomatoes and watermelon prefer warmer temps.
to germinate. You can start them upstairs in a warmer place, and move them
under the lights once they are up. It's worthwhile to buy a sterile seed
starting soil-less mix to pot them in. A small fan nearby to provide air
circulation is useful to help prevent damping off and to help the seedlings
stay stockier. Water from the bottom and fertilize sparingly once they
have true leaves.
