Storing for Winter

[Anthony Darby]

Not sure I should put up with your sauce David?

Oh, come on Anthony ... catch up ... !!!  

  If you mint that, I'll send you to Worcester, Cliff!

Name that sit-com: " I don't mind what I eat as long as it don't drown taste of HP sauce".

What was the sauce my Uncle Tommy called "stingo"?

There you go - except mine are much older so not so fancy looking !!!

25W on a quarter square meter seems to be on the high side. I would not use it without a thermometer at pot bottom level.
To compare, A single pane of glass will let through approximately 4W/degrees C and square meter The beer mat gives 100/ square meter That corresponds to 25 degrees difference on a single pane glass. A beer mat at the bottom and polystyrene lining on to will give too high temperature.
A good thermostat will work of course.
Bottom heat mats used for propagation will work well if the thermostat can be set low enough.

Sorry, didn't mention - I've got the thermostats aswell.

You can buy heat mats of half a metre square or smaller for putting under fish/reptile tanks. Don't think they will tolerate damp though?
