Germinating seeds without heated propagator - help

[peridito]

I've been v stupid and carried away with my lovely thriving Aldi plug plants ( outside in a plastic propogator ,cpvered at night ) I've bought seeds .

I've put some in little cardboard pots and some in some small cell cheap propagator trays .

But now I'm thinking window sills won't be adequate and that they will need more warmth .

Please - any tips ,advice ?

window sill will be fine. as long as it's above 15 degrees.
until seeds come up they don't need light. so you could even have them in an airing cupboard or next to the radiator behind the sofa for example and then transfer to a lighter spot once shoots show.

I do all mine in an unheated propagator on a sunny windowsill, they always grow.

Oh wow ,thank you so much .Can't tell you how that's cheered me up !

The cheap trays have lids .Should I put the individual cardboard pots with seeds in plastic bags ? And open them to vent in the day ?

Have to go out now so if I don't reply ,dont think me rude !

We've put our tomato seeds on the sunniest windowsill without lids, they've all grown!

If they have lids you won’t need plastic bags. Mine have always been fine on a sunny windowsill or on the floor in front of the sunny patio door.
