It seems that I'm quite successful at growing pumpkins, cucumber plants and evil, bitter gherkins. The excessive heat and dry weather is making the cucumbers taste so bitter that smelling them is enough. I tried to eat one and it was so horrible the taste was in my mouth for half an hour. The cucumber plant in the greenhouse is going crazy, but I can't see any cucumbers on it so far.
Supposedly I need to pick off the male flowers to prevent the cucumbers from tasting bad. I'll have to try that.
