Hothouse

Hothouse is one of the Buildings in Frostpunk.

Acquisition
Hothouse is available after finishing research Hothouse (Technology), then it can be built from Food tab. It differs from the Hunter's Hut in that it only requires 10 Workers to be fully staffed and provides twice the Food output compared to the Hunter's Hut. The downside is that it requires a valuable Steam Core to build and must be adequately heated in order to function.

Description
Produce 30 Raw Food/10h

One of the hallmarks of civilization is ability to cultivate agriculture; the cultivation and breeding of animals and plants to provide food, fiber, medicine, and other products to sustain and enhance life. However, due to the rapid arrival of the New Ice Age, most of our crops and seedlings were destroyed before they were able to mature or be harvested. The vast majority of plant-based crops cannot grow in the extreme cold weather, and the few hardy species we had were either eaten into extinction, or were not able to adapt fast enough to the new climate. Forced to find alternative sources of food, it was discovered that certain species of algae, mosses, and lichens are edible and rich in protein. These hardy crops can be grown within improvised Hothouses, and while these algae, mosses, and lichens are not particularly tasty, it is far better than starving to death.

Fan lore
If we want to be able grow other plants than just algae, mosses, and lichens, then we would need to set up a full-industrialized hothouse that has a completely sealed environment and thick glass windows that allow light to enter and keep the warmth inside and the cold outside. That would theoretically allow us to grow Old World vegetables or fruits like Grain, Tomato, Potatoes, Corn, and maybe even Apples and Pumpkins.
