What would be the best to represent hydroponics systems in game (i was thinking about refrigerated cargo bay)?
I think that makes sense.
Is there any idea how many people could 1 ton of hydroponics support?
An square meter of hydroponics generates about 100 kg of food per year, depending on the crop.
A person needs about 1.5 kg per day, so 547.5 kg per year. Call it 6 square meters per person as a baseline. With a full crew of 53, that's 318 square meters.
If we assume that you need a *cubic* meter of water to support a square meter of hydroponic (probably not) that turns in to 318 tons.
If you only need 10 centimeters of water on average (which is the depth of most standard hydroponics trays I found), it'd be 31.8 tons.
If you want enough to cover additional people, bad crops, mechanical failures, etc, you likely need to boost that tonnage anyway.
How additions of that two systems would change look of dropship outside?
What's the second system?
Hydroponics would be inside the existing cargo areas presumably, so no exterior changes.
