2 weeks ago I sowed two types of tomato seed and I kept them in a unheated propagator on a window sill with lots of light and warmth.
Yesterday I re-potted them into plugs, (they are about 2" high by now) and, left them in my unheated shed which has lots of sun during the day.
When I looked at them this afternoon all but 3 had wilted and are now lying sadly on the surface of the soil!
I only re potted after the first pair of true leaves had appeared.
Have I over watered or is it due to a drastic temp change and why have 3 survived and the rest not?
Any help appreciated
