Glass Greenhouses for Tomatoes + Plastic for Cucumbers

[Galileo]

On last Weeks gardeners question time BBC Radio 4 Bob Flowerdew mentioned that Tomatoes prefered glass greenhouses while Cucumbers prefered plastic greenhouses. He did not give any reason. Anyone have any ideas why?

The double skinned placcy ones tend to have more diffused light, which cukes like, and the blowaways/polytunnels seem to be moister inside.
Not all placcy ones are like that though

I agree, it's more than likely something to do with light transmission. One of the older chaps on our allotment site always grows his cukes in an old greenhouse frame covered with shade netting instead of glass/plastic and gets great crops.

I used to grow both in a glass greenhouse and now grow both in a plastic polytunnel. They do fine in both.
