I have sown some seeds and all look to be doing ok in unheated greenhouse, some seeds have started sprouting.
I have mine in trays with propagator lids on, only remove them to water.

so i would say yes.

If its not a cold day, leave them off. it prevents condensation and the risk of damping off. Once germinated, the need for any heat is very much reduced.

Thanks for the information. Two contrasting approaches, very interesting.

OK I'll give you a third ... no I agree with Piglet.

The cooler you can keep them (within reason) the better they will be. If they get too warm they will get leggy and weak. I would even go so far as to risk them out in the greenhouse full time but with the lids on for the last hour or so to build up a bit of warmth in there and it it gets really cold, drape some fleece over.

Or you could put a parafin frame heater under the staging at night and it will give enough back ground heat to keep them going.

Thanks NTG. The greenhouse over the last couple of days has been quite warm, so that has been fine, and of a night, I bring them in to the heated conservatory, just to be on the safe side. Do you think I'm doing right.

What are they WH?

The most important thing is to try and keep a constant temperature. At this time of year my soil thermometer is in constant use. Personally, I use lids until the seeds have germinated then I keep them with just bottom heat for a week, then take them off all heat and sow more seeds in my propagator.

Good luck

I have a couple of variety of tomatoes on the go, and some bedding plants, but not to many.
