Scarlets Cut Flower Patch 2022/23/24

Ladies, FEW and Scarlet, do these flower seeds need continued bottom heat after germination and pricking out at this time of year?

Everything I've sown so far are "hardy annuals". I do have a heat mat in the greenhouse - so somethings are on that but mostly I just cover over with lids if it's forecast very cold. I take out of the prop the minute I see germination.

I’m in the same camp as Scarlet. Mine get bottom heat till they germinate, then are whipped out once they show and kept on the windowsill with a cover on. Tough stuff like antirrhinums, calendula, cornflowers go straight to a cold greenhouse as soon as they have germinated. My big problem with sowing early is that the windowsill ones can get stretched and spindly. If I’ve got a good lot of saved seed,I still think it’s worth a try with sowing early though. I can never wait to get started with it!
