A week or so back I bought some Cos lettuce plants from a local

They are growing well and fast in the 'raised bed' bags but so far they
don't look like the picture on the label :-)

At the moment they are more like a leaf lettuce than a heart lettuce -
but it looks as though the heart is beginning to develop.

If this carries on, I think I will have a lettuce heart and a more or
less redundant ring of leaves around the base.

So when can I pick these outer leaves for an early crop without
compromising the forming of the heart?

You don't say what variety they are.

Just checked and they are Little Gem Delight.

They certainly seem to be going for it.
