More warmth required

I have moved my mini greenhouse! The seed trays I brought inside a few days ago (see here) are already looking more promising, so I suspect my greenhouse was just not warm enough for them. The greenhouse used to be in the most sheltered corner of the patio, but this meant that it didn't get any sun until mid afternoon. I've moved it onto the West facing wall, where it is a little less sheltered, but should get sun  from early afternoon (not this week judging by the weather forecast!).
