Growing Cleome from seed.

Hi, I'm trying to grow Cleome from seed. I sowed them on top of the compost and left them in the fridge for two weeks. As you can see they're now on a heated propagator. Should I leave the lid on? 
Thinking it might be too humid in there and they'll go moldy and not germinate.

    I think you may be working too hard. All you need is some damp compost and a bright place. I would take the lid off and turn off the heat and see how it goes.

    I sowed cleome in my heated propagator (set to 25c) in my unheated greenhouse on 18 March.
    I didn't put them in the fridge first.
    I think it took about 2 weeks for the 1st to germinate and the others came up over the following week or two. Once germinated I turned the thermostat down to 20C.
    They're now about 2" high and the thermostat is at 18C.
    After sowing I left the lid on, but left the vents open (just as you have).
    Once they germinated I keep the lid off wen it's warm enough in the day and put it back on at night as it still gets very chilly overnight in the greenhouse. 
    It's the first time I've gown them since I was about 10 years old which was a long time ago.

    I’ve got some that have just germinated.  I didn’t put them in a fridge.  They are on a heated propagator like yours, with the lid on.  They took about 10 days.  I will now open the vent on the lid for a couple of days then remove it entirely.  They are in an unheated GH, so I will keep the propagator on for a few more days

    I sowed mine (got from seed swap) in an egg tray, didn't cover, no heat, left on a south-facing windowsill, and they've germinated.
