plastic walk in greenhouse

Hi i have a cheap plastic walk in greenhouse, wondering if i could put my tomatoes,cucmbers,gazania,peppers and chilli out into to it now as they are on the windowsills and think they may benefit from the more light the y would get outside.. just was not sure if they would be warm enough outside?

 

Have you a thermometre you could put into the greenhouse overnight and see what temperature it falls to? It's been quite warm the last few nights. Is the greenhouse in full sun or against the wall of the house (our patio is a sun trap and is enhanced in summer by the bricks releasing their heat in the evenings)?

 

Green house gets sun in morning and then again in evening it's in a corner next to wooden fencing. I will have to get a thermometer
I was thinking keep them in there during the day and move in at night time

 

Check and see what the temperature drops to overnight in there, as opposed to outside or in the house.
