How to Change Tick Speed in Minecraft

To change the random tick speed in Minecraft, use the command /gamerule randomTickSpeed [number]. The default value is 3 in Java Edition and 1 in Bedrock. Higher numbers make crops grow faster, leaves decay faster, and fire spread quicker. Set to 0 to stop all random ticks.

The Command

/gamerule randomTickSpeed 100 — sets tick speed to 100 (about 33× faster than default). Cheats must be enabled or you must be an OP on a server. Use /gamerule randomTickSpeed 3 to reset to default.

What Random Ticks Affect

• Crop growth — wheat, carrots, potatoes, beetroot, melons, pumpkins.
• Sapling growth — saplings grow into trees.
• Leaf decay — leaves disappear after removing the tree trunk.
• Fire spread — fire spreads faster to nearby flammable blocks.
• Grass/mycelium spread — dirt becomes grass or mycelium.
• Ice melting/formation — water freezing and ice melting.

Tips

• Use tick speed 100-300 for quick crop farms during testing.
• Values above 1000 may cause lag on slower devices.
• To give yourself OP and enable cheats on a server, use the server console.
• /gamerule randomTickSpeed 0 freezes crop growth — useful for adventure maps.

What Is randomTickSpeed?

The randomTickSpeed gamerule controls how fast random block updates happen. These updates affect crop growth, grass spreading, leaf decay, fire spreading, ice forming, and many other block behaviors. The default value is 3 in Java Edition and 1 in Bedrock Edition. Setting it to 0 freezes all random block updates, meaning crops stop growing, fire stops spreading, and saplings never develop into trees. Setting it higher speeds everything up proportionally.

Practical Uses

• Speed up farm testing: Set /gamerule randomTickSpeed 100 to test if your farm design works, then reset to 3.
• Timelapse builds: High tick speed makes trees grow instantly for forest-building projects.
• Freeze the world: Set to 0 to prevent any random block changes while you build in creative mode.
• Fire control: Setting tick speed to 0 prevents fire from spreading during demolition in wooden structures.

Tick Speed vs Game Tick

randomTickSpeed is different from the game tick rate. The game runs at a fixed 20 ticks per second (TPS). Each game tick processes mob AI, redstone, physics, and other systems. randomTickSpeed only controls how many random block updates happen per chunk per game tick. Changing randomTickSpeed does not affect mob spawning, redstone timing, entity movement, or server performance in the same way. On servers, setting randomTickSpeed very high (1000+) can cause lag because the server must process thousands of random block events per tick in every loaded chunk.

Tick Speed in Farming Applications

Adjusting randomTickSpeed is particularly useful for testing farm designs in creative mode. Set it to 300 to watch crops grow in seconds, verify that your water placement hydrates all farmland blocks, and confirm that sugarcane and bamboo reach full height. For tree farms, high tick speed lets you test sapling spacing and canopy clearance without waiting. Once your design is validated, reset tick speed to 3 (or 1 for Bedrock) in your survival world and build the farm knowing it works correctly. Some technical Minecraft players use tick speed adjustments in single-player to speed up afk-dependent processes like villager breeding and passive mob spawning during base setup phases.
