Thinly in pots? Germinate inside house, and move out to cold conservatory? Cold frame sowings? Advice, please.

Unless you want early leeks I don't think there's much advantage in sowing them this early.
Mine don't get dibbed out until I've lifted the early spuds from the bed they go in - so I don't start them 'til end of Feb/beginning of March.

I usually sow mine in deep trays towards the middle of February, in a slightly heated well insulated (ie around 7degC at night) greenhouse, and fed them a couple of times between then and late May/early June, when they go out to follow first early potatoes.

Growing an early and a late variety, both at the same time, gives me leeks from Setember through to March, unless we have eaten them all before then

This year I  bought mixed seed packet from T&M that can all be sown same time and harvest from early to late season in just enough quantity. anyone ese going for this variety?
