Pot Farm (also known as Pot Farm: Grass Roots and Bud Farm: Grass Roots in some markets) is a farming simulation social network game developed by Brain Warp Studios and owned by East Side Games. Gameplay involves planting and harvesting different strains of cannabis and manufacturing cannabis-based food items. Many of the plants, quests and achievements are named after elements of cannabis subculture.

It is available as an Android and iOS app, and was previously available as an application via the social networking website Facebook. On Facebook, the game was restricted to players 21 and older. Although the game could not be advertised online due to its content, it gained popularity through word-of-mouth and guerrilla marketing, and formed one of the world's largest cannabis-culture communities. The game was generally well received by critics and was nominated for Best Social/Casual Game at the Canadian Videogame Awards.

Pot Farm is a game similar to Happy Farm and FarmVille, but with an emphasis on cannabis cultivation. On mobile, the game is free-to-play and requires an internet connection.

The game starts with an empty plot of land, with the objective of turning it into a profitable cannabis farm. Progress in the game is tracked by the player's character level, which is increased by experience gained from tending crops, earning achievements and completing certain quests. The higher a player's level, the more types of seeds they can grow, products they can buy and sell, and upgrades they can make to their farm.

Crops are grown from seeds purchased with coins (the game's primary currency) and sold for a profit. The game's secondary currency, potbucks, are earned by gaining levels, planting rare seeds, and from earning achievements; they can also be bought with real currency through microtransactions. Coins can be used to buy decorations and upgrades as well as seeds; potbucks are used for reducing grow times and purchasing rare seeds and special items.

While most other farming games have a "withering" mechanic which causes untended crops to lose their value, Pot Farm has a "protection level" for its crops. In the Facebook game, if crops are not balanced with guards and other protection-enhancing items, there is a risk of a character called Ranger Dick appearing and confiscating stash and crops. A minigame-like feature called 'Gold Rush Mode' was also available, which has been compared to Bejeweled, in which potbucks could be gambled for a chance to win many more. These aspects are not present in the mobile game, but posting more people around the farm has benefits including quicker grow times, more money from sales, and more experience.

Pot Farm was developed Brain Warp Studios, specifically by Josh Nilson and Galan Akin in 2010, and published on April 20, 2010. The success of the app led to the creation of East Side Games in 2011, which the developers founded with Jason Bailey of SuperRewards. They had received $1.5 million of angel funding by July that year. The developers have reportedly only given one interview about the game, and used the "Uncle Floyd" character persona from the game to do so. East Side Games is based in Vancouver, and its sister company LDRLY, which specializes in cannabis mobile games, is based in nearby Nanaimo.

A representative from LDRLY spoke to Canadian media in 2019 about the publishing of the game, saying that "[they have] always made their mark by doing something different, [they] wanted to build this community out of nothing. It was a great business opportunity because there wasn't a market for it, and very few other games in that space".
