Poor greenhouse crops this year

[gumboot]

Has anyone noticed that greenhouse crops seem to be very slow developing this year? I've got an unheated greenhouse and all my greenhouse plants were started off indoors in hearted propagators. My all-female cucumber plants ( grown fro seed) are far from thriving in the greenhouse and haven't even shown any signs of forming tendrils yet in their ten inch pots. My tomato plants (also grown from seed) are don't seem to be growing very well and are still in their three inch pots.
I'm getting concerned about this. Is anyone else experiencing similar problems? Is it down to the weather?

Thank you.

It will be due to the cold weather. The night time temperatures have been very cold with frosts all last week where I am. This will slow the growth down quite a lot. It should be warming up now so you should notice some faster growth.

Thanks Hawkwalk. I thought the same too.

everything is slow this year. Got hardly any veg coming through at the moment. Last May I had kale ready.
