well brum, being a ninja, (well on saving cash! 3 women in the house!) I got my hands on panel heaters.. they are rubbish for heating a room or drying clothes, BUT, they cost pennies to run, typically less than 5 p a day, and that's them on all day. I have two, back to back on a wooden frame I constructed, connected to a thermostatic plug, I am finding just how powerful they are. Currently have a tent of bubblewrap inside my gh, it's a big 'tent' because gh is 10foot by 12. Basically tent is 2/3rds.. before I got the thermostat plug these two were keeping the gh at 18 degrees lol.. So next year I'm going to have bubblewrap up to about 4 foot wrapped around my staging, obviously moved inwards from the walls, but I think most stuff will be fine, quite tempted to see if just them two panels can keep whole gh frost free, if not I could add 2 more, honestly, 20p per 24 hrs, how can u say no? By the way, I do have the thicker safety glass due to my young kids, just incase that makes a difference.
Price for the heated bench is prob pennies a day btw.
