WATER WITH A LOTTA BOTTLE

I collect cold tap water runoff, which you need to run before it comes hot, into saved empty milk bo les. These go into my polytunnel under staging or in any spare space – there could be 50 or more bo les! In the winter, any sunshine warms the water in the bo les slightly, which raises the temperature in the tunnel very slightly at night. Then in summer I have lots of water saved to use when my water bu s are all empty.
