Hang on - inside or outside the greenhouse, and where do you live?

Hops are a cool-climate plant, from choice, and vines like a warm
summer. There are a dozen or so suitable species of climber for
outside where I live, and hundreds if you get a couple of hundred
miles south (like 90% of the contiguous USA). Few of those I can
grow outside will grow inside a greenhouse, where I would have to
grow some of the heat-tolerant climbers (even with our minimal
summers).

Vines aren't terribly prone to pests when grown outside in cold
winter areas, though there are some, but most plants are when grown
in warm greenhouses. And so on.
