Greenhouse cucumbers

This year I decided to grow two greenhouse varieties side by side, as I could not decide which to grow. I planted little leaf and telegraph improved and both are doing fine. That said, the telegraph plants are huge, with leaves over 12 inches wide. I have had to remove sections of the plants, as they were starting to push against the polycarbonate panels and were actually forcing the panels upward. I must admit that the cucumbers are worth growing though.

 

These are the best tasting cucumbers ever, but, I am going to have to remove them soon, as they are completely taking over the greenhouse because the plants are so BIG!

 

They're huge! More like marrows than cucumbers Hydrogardener.

 

Have they been pollinated?
We usually remove male flowers on "Telegraph", to stop pollination and bulbous fruit, which contain seeds.

One of the reasons "all female" varieties were introduced.

 

They were grown hydroponically in a screened greenhouse. There are no insects in the greenhouse to pollinate them.

 

Still look a funny shape to me, do they contain seeds?

 

They do have real tiny seeds.

 

I had a few cucumbers on my plant in the greenhouse and now some of the baby ones have turned yellow or brown. What have I done wrong?

 

Sorry, I only grow hydroponically, so I can't offer any advice on growing in soil.

 

The trick is to keep cutting them when they get large enough, if you leave them on the plant too long the newer ones tend to stop forming and usually go yellow and possibly rot.
Its better to pick them young rather than leave them on the plant.
