my tomatoes and sweetcorn and cucumbers are spending their nights in a plastic growhouse and the days outside in my sheltered yard near the sea.
how high do the night temperatures have to be for me to leave the tomatoes and sweetcorn out overnight safely? the nights seem quite warm this week (6-8 degrees C) and there isn't any wind in the yard...
can i put squashes with one true leaf out in the growhouse or are they too small?
thanks in advance, i'm so proud of my little plants i'd hate to kill em now!
