Hello all,

I've recently grown a variety of tomato plants from seed in an electric
propagator. For whatever reason (perhaps too high a temperature?) the
seedlings are very leggy. The first leaves are typically 3-4 inches
above ground level and the stems are so thin that the plants are having
difficulty standing up straight.

I'll shortly be looking to transplant them into pots but am wondering
if it would be beneficial to plant them somewhat deeper than their
current level. I'm sure I read somewhere that this is generally a good
idea with tomato plants as they'll sprout new roots from the buried
part of the stem. It would also make the seedlings rather less
top-heavy than they currently are. My question is, firstly is this a
good idea and secondly if it is, then how deeply should I be
transplanting them?

Thanks.
