Growing Cucumbers

[Debs1 10]

I'm growing 2 different varieties of Cukes outdoors, good growth, loads of male and female flowers, loads of baby Cukes but after about a week the baby Cukes are aborting, dieing off and a bit shrivelled, have tried hand pollinating from male flower, but can't even see any pollen?

 

any ideas, where I'm going wrong?

almost certainly toogreat a difference in temperatures between night and day, I would say Debs, assuming you are not overwatering of course!

Thanks for that, can't do much about the overnight temp and I've cut down on watering too, I don't realy know.  Any idea why there seems to be no pollen on the male flowers?    This is proper doing my head in!   Spent hours on google and can't work it out.
