The message
from "Neil Smith" contains these words:

Dear All,
first attempt at gardening. I planted some seeds, prior to planting out in
the garden. within 7 days some decorative cabbages have shot up 2/2.5" and
is now bumping against the plastic lid of the propagator. The propagator
which is sitting on a ledge beside a south-west facing window and does a
little direct sunlight. Is the situation healthy.


Take the lid off. Everything sounds nice to me.
