One of the many things you can produce on your farm is BUTTER. Here's how to do that!
Butter x4 - Head on over to the Dairy and give your worker 3 Milk and 6 Northern Lights to churn out 4 sticks of Butter in 5 minutes.
Butter x40 - If you've got the Dairy upgraded and give your workers 18 Milk, 24 Northern Lights, and 1 Super Silver Haze they can churn out 40 sticks of BUTTER in 3 hours.
The Dairy contraption (blue building with white tanks) is unlocked at level 18 and produces the following:
- Butter (1 worker)
- Ice Cream (2 workers) *unlocked at level 26
- Chocolate Milk (3 workers) *level 33
- EVEN MORE Butter (4 workers) *level 40
- Banana Split (5 workers) *level 50
Remember that you will need to perform maintenance on these contraptions with Materials after you run them several times, so be prepared for that!
