Yep, lack of light is the main culprit. You need a fluorescent fixture
within a few inches of the top of the plants. The best thing is to put them
out in a spot that is sheltered from the wind, temps. at least 55, on a
sunny day. Even a few hours of real sun now and again works wonders; it
also helps prevent damping off. Of course you have to be around to bring
them right in when the temperature starts to drop.

You can also brush your hand gently over them now and again to help
strengthen them. And, as someone else mentioned, when it's time to
transplant them , you can bury a lot of the stem. Tomato seedlings are
fairly forgiving.

Good luck,
Sue

Having a problem with spindly tomato seedlings - can't get the stems to
thicken up. Would it be a lack of light or too much light that would cause
this? The seedlings are a couple weeks old and about 3 to 4 inches tall.
Any ideas?
