Initial Price	500
Base CpS	2
Max CpS	20
In-Game Description	Grows cookie plants from cookie seeds.
Introduction	1.0 Update

The Farm is the third cheapest building you can purchase and has an initial cost of 500 cookies. It produces cookies at a base rate of 2 cookies per second. 100 farms cost roughly 3,914,374,835 cookies.

From the time it becomes more efficient than Grandmas (when Grandmas cost 132 cookies to buy), it's unfortunately all downhill for Farms. They are the building that (as of 1.036) becomes obsolete fastest and stays obsolete - Cursors have Thousand Fingers and similiar upgrades, while Grandmas have grandma type upgrades and the Bingo Center/Research Facility. Factories will become more efficient than Farms when Farms cost 661 cookies (price of your third farm), although Farms may just have otherwise paid themselves off in the time it takes for you to save up for a factory at that point.

Upgrades

Farms can be made to become more productive by purchasing the following upgrades from the store:

For upgrades in beta versions of Cookie Clicker (if any), see Cookie Clicker Beta.

Trivia

• Farms have the lowest CpS of any fully upgraded Building when a reasonably large number of Buildings have been purchased, meaning that their greatest use later on is improving the CpS of fully upgraded Cursors. The 150th Farm costs 533 billion cookies but only increases the output of Farms by 20 CpS (before bonus multipliers) with all upgrades; it however contributes 26,520 CpS (plus multiplier) to the Cursor rate and per mouse click, if you have 200 cursors and the Quadrillion Fingers upgrade - a 1326x difference(!).
• It has been confirmed that the farms will be the first to get a content upgrade on the scale of the 1.03 update, which re-introduced the Grandmapocalypse.
• Farms were not included in the Classic version of Cookie Clicker.
