Just saw your comment @Sheps - sorry. Yours look absolutely fine after their transplant. Good job. They're quite easy when it comes to splitting up, even when small. They should establish well and really thrive over the next few weeks. You'll need to get a rabbit if they all grow too well
Mine are still much the same - not really warm enough yet for them to get going properly. I did them earlier than I normally would, just to see how they'd do. I knew it probably wouldn't work but that's what it's all about - experimenting now and again.

Hi everyone...tonight is going to be cold, only a couple of degrees or under, so I was wondering what sort of temperatures can Lettuce seedlings take in an unheated greenhouse?
I've never had them in a greenhouse at this time of year, so can't really advise. It was zero/minus 1 here last night, and the kitchen was 11 degrees when I got up. I wouldn't want them being below about five degrees or so at the tiny seedling stage though, but it's not something I've ever experienced. When they're fully grown plants they can cope down to zero though.

@Sheps, I would say that they would be ok, the biggest problem will be if you have a huge temperature differential between day and night, at this time of year it can get very warm during the day. On days where we have lots of sun I put the seedlings outside during the day and bring in as the temperature cools. Try to avoid making them too damp and it won't hurt to give them a fleece cover or even a sheet of newspaper will suffice just before dark.
I think that would be wise @Sheps - they haven't even got true leaves yet, and you've just moved them on, so they're pretty vulnerable. That swing from hot to cold if there's sun is always tricky as @scroggin says - even with hardy annuals that are further on. Better safe than sorry.

Hi @Fairygirl and everyone else, I'm trying to protect the seedlings from the worst of the sun whilst I'm at work, so will fleece give enough light transmission while the shade is doing its job?
Or, is there a risk of them getting leggy, if lettuce do that sort of thing?

Carrots and Onions are next, just waiting for the seeds to be delivered, it's quite addictive this growing from seed.
