Leggy leeks

To give a short and sweet answer........ Yes 

Thanks. I can get a good nights sleep now

By that I assume they are in a container of some sort, as are mine. I started mine in a trough outside down the lottie (not enough space for a seed bed), they are grass like, and are being watered regularily. They are hardy things, when you can I would move them out of the greenhouse. 

.. and make sure they're in nice deep containers or else the roots will form knots that would mystify a seasoned sailor and you'll never get the individual plants apart to transplant them (I learned the hard way )

I wouldn't worry, I'm  sure they'll be fine - Look at Johns video on planting out leeks here :

All a bit tangled but ok  in the end
