I'm growing leeks for the first time this year, so I'm heartened to hear they're tough! I was planning to grow them in a seed bed though - I've made the bed, and it's got an old shower screen over it atm to warm it up a bit. It sounds like everyone here sows them indoors though. I suppose you'll all get much earlier leeks. I'm trying to limit the amount sown indoors to the strictly neccessary, because I haven't got much window-sill space.
If you grow them from seed into a big deep polystyrene veg box you don't need to pot on.You'll get good foot tall plants ready to transplant dead easily due to the depth of the compost. ;)
