Minimum night temperature Toms and Cues

My Grow-house in my cold conservatory is not going below 10C at night (the last two nights were 10C and there was a frost both nights)

Is that warm enough for Toms, Cues, Peppers, Aubergines, or do I need to continue to bring them in each night?

On Sunny days they are getting up to about 30C (minimal ventilation, if we get a hotter day I will ventilate them - so 30C is the max really)

 

I would say that's ok Kristen my brugs have managed on 6-7c this winter (same family as toms) at 10 c they will continue to grow slowly.

 

I always used to wait until mid April before planting toms in an unheated greenhouse and make sure the plants are strong and hardened off.

By that time although the nights are still nippy they are relatively short.

I'd say 10C at night is fine, a bigger problem is a prolonged spell of dull cold weather when the greenhouse doesn't warm up during the day, not unknown at this time of the year.
