Why would it be humid? Heat doesn't cause humidity. Deserts can be hot and dry. (Edited are to can be for the pedantic people.)

Plants/watering cause humidity and the glass traps it. And although I guess they probably could, people aren't generally maintaining desert ecosystems in their greenhouses.

This is not a problem in the winter -- outside air (if brought up to room temperature) is extremely dry. So just a bit of air exchange would dry out any jungle if humidity is not supplemented.

It's a 10 year old house so it has survived a few winters already...in Sweden.

I assume by "...in Sweden", you are implying Stockholm gets fierce winters. But it doesn't really. It gets a lot of sun (comparatively) and not much snow. I was wondering about real snowfall accumulation.

We have greenhouses far north of Stockholm too and they work just fine so far. They can be built quite stable and ofcourse they do that where snow is expected.

I wonder how they control humidity inside the home and prevent mildew/mould? The air in the greenhouse would be very humid all year round I would have thought?

Deserts aren’t necessarily hot, they just have very little water.

Cool, I've visited this house! It's located just a few kilometers from where I grew up. Small correction to the article though: it's quite feasible to grow tomatoes and cucumber without a greenhouse in summer in Sweden.

Depends on which part of Sweden isn’t it?

Quite. It would be difficult in the polar region. It works great in the Stockholm area though!

I wonder if this has a negative effect on the amount of fresh air that they get

Fresh air is created by plants and CO2 is taken from the air by plants, a greenhouse has plants so... probably a good amount of oxigen there

Molds are a problem and there is another, for rodents, mosquitos and cockroaches this is a dream made true. Spiders can take mosquitos easily, but the other two will need a plan

>Why would it be humid?

The hotter air is, the higher its capacity to hold water vapor.
