I never use seed compost just normal and never have many problems. One seed that I can't get to show is snapdragon. Covered uncovered under plastic ect never have joy
75% germination is pretty good. I don’t grow much in the way of flower seed but vegetable seeds of the same variety sown at the same time in the same medium can germinate at wildly different rates. I usually give them a month before I replace the no shows, but then the odd one surprises you. Till you’re ready to pot on the rest, as suggested, seems a good measure.
Mountainous Northern Catalunya, Spain. Hot summers, cold winters.
Sweet peas can be slow and there seems to be no rhyme or reason to their germination timing. I always hang on for at least three weeks after the others have come through before deciding to give up. I am unsure what is going on with Sarah Ravens "Hi Scent" as they are not showing at all despite being started off two weeks ago. I wonder if anyone else is having problems with that one?
@Old Arthritic marc I find the antirhinnums like an early start. I put "lipstick silver" and "bronze Madam butterfly" in the heated propagator on 14/2/19 and they did not germinate until at least 21 days later. They should not be covered by compost as they need light. I took them out and have them under cover now with no heat and they are doing well. I got mine from Chilterns. I hope you have success in the future.
Sweet peas can take from 2 to 4 weeks, so it depends on conditions and temps. I sowed some at the end of Feb. An experiment really as it's very early for doing them. They're covered, and in the greenhouse, but are only just poking through- a month later. I sowed some a couple of days ago, and they'll probably be quicker. I usually wait till April at least, or sow direct, but as I have more time now, I did some to get a small head start . I never use seed compost for them, but that's only because I don't sow in autumn. If I did, I'd use something with less nutrition, as you don't want them geting big and soft going into winter. You'd only be hacking them back all the time.
