Second crop of cucumbers

I planted a second crop of cucumber seeds at the end of June. In the greenhouse they are already up to the roof and taller than I am. The leaves are enormous! Apparently cucumbers don't really react to the shortening days - they just keep going if it is still warm. Despite a few cooler days it is still up in the 70s and they are all doing fine.

Another early cucumber was completely spent and finished, so I cut it back to about 2feet tall and two leaf joints - it is already up to the roof as well as having a lovely bunch of cucumbers growing.
