I always sow too much stuff Kitty. I even sow seeds from my own plants, those that would divide and give me flowers more quickly
I've used vermiculite this year, I prefer grit really but it's hard to come by round here, all too big. Grit prevents algae better than anything else for slow germinators. 99% of my stuff is hardy, sown fresh and either germinated last autumn or is germinating now. Some things are in those pots for months and moss/algae can be a problem. The aquilegias were sown at new year in the GH
I know little about half hardies and tenders. Cosmos germinate easily and someone gave me those seeds. I think aubrieta is easy as well, I have grown that, though there doesn't appear to be any in the garden now. Overtaken by weeds probably
The GH is big and provides shelter but isn't heated and the door is always open.
