Soviet Standard Greenhouse

Soviet Standard Greenhouse in two sizes: single and double.

During the glorious Soviet era, many cities with big heating and power plant, specially in the north but also common in the south, use such greenhouses in this configuration. Mainly the waste heat was used to grow plants on a very efficient scale. Cities in the far north and northeast of Russia use such greenhouses as main food source until today. This one is a 1:1 scale replica of the greenhouses used in the city of Kurchatov, Kurskaya Oblast, which is using district heat from the nuclear power plant. The same greenhouse was also used at other sites like Balakovo (Saratovskaya Oblast) or Pripjat (Ukraine, Kiev Oblast).

(!) Important notes (!): The greenhouse will only work if you connect it directly to a heating source. (!) Don't use heat exchangers, just use the heating connections of the building (!). Otherwise the heating tank will run out of hot water and the production will stop until reaching it's needed level! Don't be worried about the rapidly twitching indicator needle. It's the Soviet Union, fluctuating heat supply could be happen there! ;) When water supply will be available in the game, I will update the mod's water needs!

How I calculate the output? I use as reference the big conventionel field, which have a output of 300,35 tons of crops during one season, so 62.48 tons per hectares. The greenhouse can operate double the season, so the output will be double to 124.96 tons per hectares. Because of it's higher efficiency with the ultimate use of the sunlight and lightning, greenhouses have 80% higher harvest, including heating (+20%) and fertilizer (additional +20%), it will produce 274.91 tons per hectares. Calculated on the overall planting area of 2,50 hectares, 687,3 tons will be produced in one year, which is a maximum output of 1.89 tons of crops per day for the single greenhouse. For the double greenhouse, it will be double of that 3.78 tons per day.

For comparsion: one single field can produce 0.82 tons per day. So that means with one single greenhouse, you can replace around ~2.5 big fields, with the double greenhouse, you can replace ~4.5 big fields. The size of a single greenhouse is around the size of one big field (longer but smaller). This makes sense for advanced gameplay to feed your big population without placing fields in every vcorner of your republic or for remote cities, many kilometers away from your main supply chain.

Please note: Because of how snowmelt works, I can't remove all the snow in winter. Some tiny snow areas can be seen when snow is falling, but the most of it will melt away shortly after reaching the ground. Because the shadow disappears at a certain zoom level, the textures will be some brighter.
