Let me see if I've got this right: you have a propagator inside a
greenhouse. The heat for the propagator is off, and the vents open.
The temperature in the greenhouse is 25C (sunny day), and the
temperature inside the propagator is 40C. Goodness, what a little
clear plastic will do! Having broiled a set of seedlings with a
similar arrangement (except I had the heat on below the propagator),
all I can advise is keeping a sharp eye/ear on the weather. If it's
going to be sunny and warm, give extra ventilation to the propagator.

As for bringing the trays indoors, that'd be fine for germination.
However, once the seedlings emerge, they need light, and you'd have
the same problem until the plants were large enough to be unlidded in
the greenhouse. Perhaps someone else has better ideas.


Well, I went out and had a look to see how things were going and several
tomato and chilli plants have now germinated. They must like
temperatures in the 30s and 40s (C). I only sowed them on 31st March and
they have germinated already. I think I have accidentally given the
seeds ideal germination conditions. I haven't seen any aubergines emerge
yet though (they were sown on 28th March).

I think I'll just carry on as I am and switch the propagator on at night
and take the lid of on a sunny day. Seems to work, by trial and error.
