House within a house

This year the garden is lacking any winter vegetables.... because just as the autumn planting season arrived I was hospitalised and therefore didn't have a chance to plant anything.  The neighbours are very kind and often bring armloads of spring onions or Chinese cabbage, but it is always nice to be able to go into your own garden and harvest your own vegetables.  

Last year I had good success in the tunnel house from about now on, but this year our tunnel house is looking a little worse for wear - with holes in many places, and one door that has basically fallen off.  The new plastic has arrived to re-cover the entire house, but finding time to actually do it is going to be a bit of a problem.  In the meantime I have created a house within a house and have managed to get a few radish seeds to sprout.  Hopefully the spinach and lettuce seeds will also follow soon, but I'm guessing the huge temperature range that they experience each day may not make for a highly successful experiment.  Roll on spring...
