These last couple of days, the temperature in my greenhouse has got up to 42 C, with all the windows wide open.
I've got some seed and seedlings in there - toms, cukes, various beans, okra, aubergines, courgettes, and some flower seedlings.
Are these things ok at that temperature, or should I be putting the shading up? The courgette seedlings were in full sun the other day and were looking very droopy, even though their compost was nice and moist.
