Unbubbling the greenhouse

I was away for a few days for my birthday - when I left, it was still very cold at night and I didn't want to remove the bubblewrap too quickly. 

But today I couldn't leave it any longer - the seedlings in there were really struggling and one tomato plant had died. 

It's forecast to get cold again next week, with some frosty nights so I thought it best to leave the bottom insulation but remove the bubblewrap at the top and back, which should also let a lot more light in.
