Thanks I still Carnt believe they germinated sew about 50 seeds though and only two came up

Maybe they will be super heavy weight giant onions. They germinated after 6 years, so must be survivors. You never know  ;)  :lol:

Good germination from Hylander but still not very good from Isobel Rose, so I've moved those into the propagator, perhaps they need a bit more heat than the others.
Snowboar, sorry can't help as I've never used lights.

Grow lights- I move them out and into the greenhouse at the end of January usually. This is partly due to temperatures but also light levels, which improve a lot over the month. I harden them off and plant them out in May as a general rule, but you need proper spring like conditions and a cloche or fleece on standby for late frosts.

Feed - yes. I use a weak Baby Bio solution when they are in the house, because it lives under the sink and I use it for houseplants. They get weak veg feed once out in the greenhouse.

Potting on I leave until they straighten up and start on a second or third leaf. If you feed them, they can stay in a starter seed tray or pot for a while without harm and they are less fiddly to handle  :)

If the greenhouse is heated and insulated, I would say you go straight from one to the other, so long as temperatures are not too severe.   I have to faff a bit more and move them onto cool, but bright windowsills indoors before I trust them to the greenhouse.

We are forecast some cold nights over the next week or so, so I might well hang on until the first or second week of February this year  :)

Can I join the onions-from-seed club?
I've only grown them from sets before, but have somehow acquired a packet of onion seeds (why are seeds so good at jumping into the shopping basket?)
I have found the article on the main site about them, but does anyone have any useful advice or want to scare me away?
Would they be happy starting in the airing cupboard till they germinate then going onto a windowsill in a cold room? (It gets the most light of all the rooms in the house.)
Thanks
This post is 100% biodegradable and can be composted after use.

To give them a bit more reflected light a plastic survival / space blanket can be hung off the curtain track , selotaped to cardboard or similar.
You can get a few for very little money off an auction site beginning with e !

I've sown some more Isobel Rose and Long Red Florence, fingers crossed for 2nd time lucky!!
