Omelet,

I have considered shade cloth over the greenhouse, but I fear that the
reduction in sunlight would not be beneficial to the plants,  We are
in a coastal area and have fog and overcast a good part of the time.
The problem seemed to be that when we do have full sun it raised the
temperature of the soil in the pots (not the plants) too high.
Shading the pots seems to be accompli****ng this.  I await further
developments.

There is a large hatch in the roof and one at each end of the
greenhouse.  All three are open and there is no condensation inside.
The only way to increase the ventilation would be with a fire axe.
