DigiFarm

The Digi-Farm is where Digimon that are not traveling with you can live and train. This is also the only place where you can have a conversation with the Digimon you have been training. Upgrades At the stores there is often a Digimon vendor that specifically sells upgrades for your Digi-Farms. It is even possible to buy new Digi-Farms from them.

BGM
The background music (BGM) that plays at a Digi-Farm effects the efficiency of a Digimon’s training there. This is based on what species the Digimon is. Each song benefits some while hindering others.

Terrain
Planning ahead Every Digimon line needs certain types of species exp to Digivolve to their farthest forms. If you are having a hard time raising the required exp then place them on a farm that has a matching terrain. By the time they are strong enough to Digivolve they will have an easier time meeting the requirements. The terrain at a Digi-Farm is the deciding factor on how much base experience a Digimon will gain every time cycle while training there.

Even if a specific type of experience is not a Digivolution requirement for one if the Digimon at that Digi-Farm it is not a loss. For example let's use Duck version's starter Lunamon. The Dark species type Lunamon will never have a good use for Bird or Machine experience. Its farther Digivolutions only require high friendship and Dark experience. This does not mean gaining Bird or Machine experience is useless. Experience types that are not requirements for anything related still count toward that Digimon's total experience and gaining levels.

Talking
When a Digimon spends a long time being ignored in the Digi-Farm their friendship percentage will go down. To prevent this you should talk to your Digimon every once in a while. If you talk to them frequently their friendship percentage will increase.

Quizzes?
Sometimes when talking to a Digimon will result in more than a random quip. They will ask you a question that is both Digimon related and can be found in the game itself. You will be given 2 answers to choose from. If you answer the question correctly then you will win a random item. Nothing will happen if you got the question wrong.

Farm report
After enough time passes you will receive a report about updates on your Digi-Farms and their inhabitants.

Digimon stats and level increases Events Food production and use At the beginning of the report you have the option to read it or skip it entirely.
