O2 marble like farm + switch

O2 marble like farm + switch

This list is intended for just ONE farm, and the first photo may be utilized differently, not for two farms.

The list includes:

- one O2 farm (90 x 70mm) ,  This is 3D print Marble-Like PLA, not real marble.

- switch connector part (used to connect other farm part, also can "open and close pad")

- now got red cover (ant can not see red color, so they will think it is black dark undergrand, but we can see though red)

- top right side have a water area, add water and it can keep half of nest moisture.

- syringes included

Once the colony grows, this farm can be connected to more O2 farm using a "switch part," and it can be connected to as many as you like. This way, you can expand the farm as the colony gets bigger and bigger.
