My Sturon seeds will be going in a planter in the spare bedroom, (under glass until they are about 2" tall, then into the garden room, which is insulated, but with the heating off it stays at approx 10c), on Saturday. I'll try and post a photo next week  for reference purposes.

been away for a couple of days  back home and  toiling with the idea of starting some onion seed of in a propagator  got Globo and Robinsons mammoth red and white sounds like some of you have already been sowing onion seed

Q. having sowed the seed in a tray in the  propagator  should I sow in damp compost? and hopefully when they get to the crock stage prick out into pots

Q. after potting on do the plants need heat to keep them going in my greenhouse

I ask these questions because I've always sowed onion around mid February but I suspect the early sowings get bigger bulbs?

I sow into a small seed tray and prick them out into modules, but I leave them to develop a 2nd leaf first.  If that takes a while, a weak liquid feed can keep them going in the seed tray.

An unheated greenhouse is not ideal at first.  They don't need a lot of warmth, but frost free is a minimum, plus good light levels. 

Maybe try a few seeds and see how you get on, then you have some backup for Feb sowings.

I sowed mine at home last year and soon as they germinated I transfered them to my unheated polytunnel, coddled in bubble wrapped propagators (as pictured) They grew well despite the frosts we had.

I've used the foil on cardboard idea on the spare bedroom window and it works pretty well. Ailsa Craig were good for me and Yellow Rijnsburger. The latter are such a nice looking onion, both growing and in store.

I usually grow onions from seed but had trouble germinating Red Barons last year so resorted to sets, not the same ! Am trying Red Brunswick, Ailsa Craig and Rignsburger this coming year and more of them as I had ate all mine by Christmas :tongue2:

I grew from sets and seed last year having all round good results. Definitely will be planting a few trays of seed that are destined for the kitchen window, OH will love that!  :wacko: how she loves a tidy kitchen!

for those of you that have gone with the cardboard and foil method I can remember a friend of ours making a wooden box lining the inside with aluminium foil with a light bulb fixed on the top centre presumably it was the same idea as yours for propagation heat and extra light

perhaps this mite be a better idea when the onions have germinated to put them in the box and I'm not sure how big the box would need to be for the coverage of the light bulb

but as said some of you have just put the seedlings in the poly tunnel covered in bubble wrap depending on the replies I mite consider making a propagator box  :unsure:

My giant onions are coming along nicely, 7-9" tall now with some Heath-Robinson supports added.

They look like they are doing well  :)

I had to re-sow after the first lot of seed failed  :(  Internet supplier, but fresh stock (or so they reckon  :unsure:).

Anyway, Suttons to the rescue, as I was ordering something.  I can see little signs of life already  :)

I bought my Globos from Sutton and sowed on 26th Dec but no sign of life yet despite greenhouse not dropping below 8C in that time
Leeks (Lincoln) likewise

Do I hang on? Do I start again?

What d'you reckon?

Hmm Sunny thatís a tough 1, you donít want to end up with too many but how long to leave it could you pre chit some of the same seed to see what germination is like?
My sister in law is ordering me 40 kelsae seedlings, never ordered any before, a bit of a cheat I know but will make a change.

I thought they needed +10C  to germinate, so maybe not consistently warm enough?
