Is it too late to start off some more leeks?

I have got 2 sets of leeks about 30 in each but the OH has pointed out we could do with more.  Is it too late to start from seed?  I looked at buying plants and there are dearer per plant than it would cost to buy.

I started some late last year.  They didn't grow huge but they were certainly as big as the tiny ones that cost a fortune in the supermarket.  Very nice griddled 

I am sure there is a place near Lesmahagow that is selling winter hardy leeks for £2.50 for 50. That is all the details I can give you but they are very good.

i sowed some last july for a trial and put them in in september ,just finished cropping them last week ,they werent as big a usual leeks but were tasty .They may only have been smaller because of the hard winter ,but  give it a go it might be ok
