I find seedlings can take ages to recover from rest. Once they start growing can't you just give them a bit more water
than for more established plants?
No, I haven't watered yet.

But you're right, their only hope is water.
These are fully developed seedlings, if you know what I mean.
They are just tiny.

What's the lowest temperature you'd dare let your newly planted seeds drop to at night?

I've turned off night time heating but there's frost due this weekend.

I let the temperature drop ~10oC at night, so it goes much lower than 15oC at night.
I have my seedlings indoors so this is relatively easy to achieve.

Thanks, I read that first as -10C on my phone but now on the PC I see you mean 10C approximately.
Looks like a min of 10C would be good alright.

I'll crank up the main heater to compensate or else just go back to manual settings.
I've probably started them too early in the year as I intended to remove all heat at night.
