'G' day tomorrow!

I have 2 full heated props in GH with chillies, aubs and toms. Some tom babies and other things on unheated gh bench. Seedlings still under lights indoors outgrowing their space as well as plants on the living room windowsill indoors, plus a tray of cucurbits about to germinate in the airing cupboard. Shortly something's gonna have to change. I have a heater in GH that will keep it just frost free about 2° and the tomatoes will just have to put up with that. They do get fleeced and bubble wrapped if a really cold nigh is forecast. I find toms cope reasonably well with the cold, it's light they crave. I'm not experienced with chillies and aubergines so I'm going to hedge my bets and have some stay in low bottom heat and others unheated but covered. They've got two choices grow or not.
The forecasters are a bit erratic though, last night one lot said +6° the other +2° in reality it was about +1°.
