Bbbrrrr. Just been on metcheck.com and the windchill for our part of Essex for the next 48hours could get to -4. Glad I have the electric heater on in the greenhouse. I also lifted all the pots from the floor and gathered them together on the staging....I figure heat rises so it will be warmer near the top of the house. I really could do with watering in there, but I keep resisting the urge because of the freezing temperatures. The insulation is working well as I still have chillis cropping, and an aubergine plant still growing! I finally removed the last tomato plant today as it has botrytis dashing up the stem and I don't want to loose everything in the house to the ravages of mould.
