The garden is the Tier II version of food generation, it produces a moderately larger amount of food, however, it is significantly more expensive. Like most other buildings the garden can be combined into a 3 wide building, increasing production and allowing more workers. It requires 70 dwellers to unlock.
To increase the speed at which Food is generated, place dwellers with better Agility in this room.
The garden, like other rooms, gains a production and upgrade cost bonus from being connected to another room of the same type and level. The rooms will gain a +2 production bonus for each connected room. Upgrade costs will be 25% cheaper for a double room and about 34% cheaper when upgrading a triple room vs upgrading 3 single rooms.
Compared to the diner, the basic food production room, the garden generates more food with slightly longer production time. The garden is overall the more efficient of the two, with a better ratio of production time to production quantity than the diner. As a downside, the garden is significantly more expensive to build and upgrade than the diner. Once the Nuka-Cola bottler is unlocked, gardens are rendered obsolete.
|Single Room||Double Room||Triple Room|
|Greenhouse Upgrade Cost||3000||4500||6000|
|Hydroponics Upgrade Cost||9000||13500||18000|
