Produces 50w for 10 days. Needs to be refueled with raw potatoes.
(Originally it made 5w but 50w seems good for game balance.)
Niche use for doing challenge runs such as permanent toxic fallout, where hydroponics are needed, but you also want to save on wood / chemfuel, but have stocked up on meals and can afford to grow a potato instead of rice. Or if you're just out of everything after a big raid.
