@Sheps, have you got a thermometer in the greenhouse? If so what temperature does it get to during the day? If the greenhouse is in full sun for a big part of the day I would put shading on the glass rather than cover the plants, I wouldn't want to restrict the airflow around the seedlings by covering them during the day. Is the door and vent open as this will help keep the temp down a bit. Once the seedlings have true leaves I start putting mine outside during the milder/ hot days to start the hardening off process.
I agree - shading is far better. It's that awkward time of year when it can get roasting hot in a greenhouse, but very cold overnight. Air flow is always important. My tiny growhouse gets up in the high twenties, or more, just now if it's sunny - but it's the same temp as outside once the sun goes, so I have to be careful with anything in there. Lettuce will tend to bolt and go to seed if too hot, although your plants aren't quite at that stage yet, so not a huge worry for now. If one side of the greenhouse is a bit shadier, you could maybe put them there which would also help. I used to do that at the last house. We had a stupidly big conservatory, but one side was much cooler due to the aspect, so I was able to have stuff on that side at this time of year.

Hi @scroggin temperature in the greenhouse is peaking at about 20°c and the vents, louvres and door are open.
I have shading on the opposite side, it's after midday when the sun reaches the other side for a few hours, will try some more shading and hopefully they will be ok.
The true leaves have just about formed, so coming on strong.
Yes - I wouldn't be too worried about that temp @Sheps just now, especially as you have lots of ventilation, but you'll just have to keep an eye on it all as temps increase . You'll be able to get them outside a little bit before you know it though. Then it's just the slugs to worry about...
I'd just like my kitchen to reach that temp a little more often so that mine would grow - they're still tiny!

A little update... I'm not sure if this is a sign of impending doom but, some of the taller seedlings are starting to fall over, not sure if this is a sign of the plants being leggy or possibly damping off, or the fact I didn't plant them deep enough.
Either way I've transplanted them into bigger pots and planted them deeper to try and save them.
Some of the ones planted deeper in the cells are thriving and doing really well, so they should be ok.
Don't worry too much. As long as they're getting enough light - ie being turned if necessary, they should strengthen up. They'll grow more or slow down too, according to temps - just like any plant would do. This is why it's easier to do them in clumps as cut and come again.
If I prick out a single plant, I tend to do it with the later sowings, as they might still be sown inside, but are moved outdoors more quickly, so they're sturdier right from the start.
