I sowed Lobelia, Busy-Lizzies and sweet peas 3 days ago. Sweet Peas are on a windowsill in the study which is quite cool and the others are in heated propagator on the kitchen windowsill. I have a heated by a cable cold frame in the greenhouse and a cold frame just by the kitchen wall for later.
Other seeds I'll sow in March. Have 2 more heated propagators.
