I grew an all-female cucumber last year and it was producing fruit in no
time. This year I bought three, thinking I would be rolling in fruit, but
despite the exact right greenhouse conditions, lots of growth and flowers,
all they have is little gooseberry-like fruits. I'm a beginner so have no
idea what the problem is, but by now I have about ten or more of these
little things and none growing any larger. Can anyone help? The plants are
well watered, also.

That seems like a problem with the stock rather than with your
management. It could be worth enquiring at the place you bought them.
