Redstone 101: an automated wheat farm in 30 minutes

1. What you need

Gather before you build — running back for one observer kills the thirty-minute target.

Gather everything before you lay the first block — running back for one observer or a missing hopper kills the thirty-minute target and tempts you to leave the farm half-wired.

1. 11 iron hoe, 1 bucket of water
2. 29 hoppers, 2 chests, 2 observers
3. 31 piston, 1 redstone dust, 32 building blocks
4. 432 wheat seeds (plant after wiring)

1. 11 iron hoe, 1 water bucket, 1 solid block for water containment
2. 29 hoppers, 2 chests, 2 observers facing each other
3. 31 piston, 1 redstone dust, 32 building blocks (cobble is fine)
4. 432 wheat seeds — plant only after the wiring is tested

2. Farm layout

Nine wheat rows in a 9×7 rectangle. Water source at the back center hydrates the whole field. Collection hoppers run under the front two rows.

Nine wheat rows in a 9×7 rectangle. One water source at the back center hydrates the entire field. Collection hoppers run under the front two rows where broken items slide — the rest of the floor is solid blocks to keep items in range.

3. Wiring the harvester

Place an observer watching the front wheat row. When growth updates, it pulses the piston behind the row, breaking mature wheat into the water stream.

Place an observer watching the front wheat row with the output facing into a piston behind the row. When any wheat block updates to its final growth stage, the observer pulses the piston, breaking mature wheat and seeds into the water stream below.

4. Testing and AFK collection

1. 1Plant seeds and bonemeal one row to force growth.
2. 2Confirm items reach the chest within 5 seconds.
3. 3Break and replace one observer if pulses misfire.
4. 4AFK at the chest chunk — no player input needed.

1. 1Plant seeds and bonemeal one row to force a growth update.
2. 2Confirm items reach the chest within five seconds of the pulse.
3. 3Break and replace one observer if pulses misfire — usually a facing error.
4. 4AFK within the chest chunk — no player input needed once rows are mature.

5. Doubling yield

Mirror the observer line on the opposite row — same piston circuit, shared hopper chain. You double output without doubling water or collection chests.

Mirror the observer line on the opposite row — same piston circuit, shared hopper chain down the middle. You double output without doubling water sources or collection chests, and the comparator lock still applies to the whole system.

6. What to build next

Once bread is passive, move to iron or a mob farm — same hopper logic, bigger scale. Our iron farm guide is the usual step two.
