Hardening

Cosmos bipannatus
Encouraged by the success of a single tray of Cosmos in the greenhouse since 22nd, I have now moved all 5 of my Cosmos trays to the greenhouse. I also moved out a tray of Marigolds, Myrtle's mini-tray of Cosmos and Krista's mini-tray of Astrantia.
Night temperatures have been warm - a minimum of 4.6 since they went out.
Obviously it's great to move things out of the kitchen, but the best thing about half hardening seedlings by moving them to the greenhouse is that they start to straighten up. The photo shows the tray that has been hardening since 22nd.
The most dangerous part in bringing a tray of seedlings out is the journey from the kitchen to the greenhouse. My Cosmos are mostly prostrate so I could not protect them with a lid for this short journey - one gust of wind and that would have been the end of them. But luckily that didn't happen.
Obviously I'll be keeping a sharp eye on temperatures, moisture levels and which windows get opened. But it is good to be moving in the right direction.
