Bamboo farm: harvests by itself (automatic farm)

fuels ~280 items smelted an hour: a double chest of ore every 12 h, a tenth of an 8-furnace super smelter at full speed · 64 bamboo stalks · 858 blocks · 389 iron to build

Harvests bamboo by itself, forever, from its 64 stalks: every block that grows is broken and its item goes into a chest. It gathers about 1,100 bamboo an hour: 1.3 for each block placed. As furnace fuel, its bamboo smelts about 280 items an hour: a double chest of ore every 12 h, a tenth of an 8-furnace super smelter at full speed.

the simple design: no flying machine, no slime blocks · 0.33 items smelted an hour per block · needs open sky or light 9 · harvests each stalk at 3 blocks tall · fits in 66×6×4

Try it

The view plants the bamboo, puts a chest under its hopper and grows the bamboo 8 times faster than the game does: watch the farm break each block that grows and send its item into the chest (the tag over each chest shows what it holds).

How this design does it: The obvious bamboo fuel farm, 64 stalks in a row: each stalk on mud over one hopper line into a chest, a piston beside its 2nd block and an observer above the piston watching its 3rd; the observers' dust behind them is one line, so any stalk reaching 3 fires every piston.

Build it

Download .litematic Download the design as text

The .litematic opens in Litematica (Minecraft 26.3): every block of the design in one region. The text file is the same build written as plain text, block by block.

After building it, plant a bamboo on each of its 64 mud blocks and run its collector hopper line into your super smelter's fuel chest: the download has no bamboo. It needs open sky, or light 9 at every stalk (a torch or lantern beside it): in the dark, indoors or underground, nothing grows; with light 9 it works day and night.

Blocks used: glass hopper mud observer piston redstone wire stone

Which to build: this is the simple design: it has no flying machine and no slime blocks. The farm that sweeps its field with a flying machine fuels more for each block placed (1.1 items smelted an hour against 0.33, 3.4 times as much), for 92 slime and its flying machine: Crop farm: fuels ~2,750 items smelted an hour: a double chest of ore every 1.3 h, 95% of an 8-furnace super smelter at full speed · 639 bamboo stalks · 2,492 blocks · ~4,400 iron + 92 slime to build.

For a super smelter: run its lines into the fuel chest of Auto-smelter: a double chest of raw iron in 72 min (100% of 8 furnaces) · ~8 stacks of coal · 108 blocks · rests.

Details: how it works, measurements and properties

In depth

harvests its crop by itself: every block that grows is broken and its item sent into a chest, forever, with no replanting

How to try it

The farm runs in the view: the view plants the crop and puts chests at its outputs, then grows it 8 times faster than the game; every block that grows is broken and its item drops into the chest at OUT. The numbers over each chest show what it holds; speed it up with the bar's speed dropdown. Drag to look around, pinch or scroll to zoom.

Measurements

metric	value	what it means
items per hour per block	1.304	items harvested each hour for each block placed, over 10 hours of game time: the farm's efficiency, what the main design is ranked by
items per hour	1119.2	items the whole design harvests each hour, over 10 hours of game time
per stalk	13.41 blocks	blocks placed for each bamboo stalk it harvests
items per hour per stalk	17.49	bamboo harvested each hour for each stalk, over 10 hours of game time
harvest height	3	how tall a stalk gets before the farm cuts it, in blocks
wait	48.5 s	the longest a grown block stood before the farm harvested it
items smelted per hour per block	0.326	furnace items its harvest smelts each hour as fuel, for each block placed (a furnace smelts one item per 200 game ticks of fuel: bamboo burns 50, a quarter of an item each)
items smelted per hour	279.8	furnace items the farm's whole harvest smelts each hour as fuel (an 8-furnace super smelter at full speed takes 2,880 an hour)
game rts	24	how fast the plants grow in the 3D view, as the game's random tick speed (normal play is 3): a farm of up to 8 plants at 300, a bigger one slower so its collection keeps up
bill	389 iron, 64 quartz, 256 redstone	what its blocks cost to craft: iron, quartz, redstone, slime

Notes from its designer

The obvious bamboo fuel farm, 64 stalks in a row: each stalk on mud over one hopper line into a chest, a piston beside its 2nd block and an observer above the piston watching its 3rd; the observers' dust behind them is one line, so any stalk reaching 3 fires every piston. The fuel farm's bar: 280 items smelted per hour, 0.326 per block. Its walls are what make it work: a piston squeezes each popped item against what is in front of it and the item shoots up and out, so glass walls in front, at both ends and over the stalks and observers keep every item in (glass lets the light through: bamboo grows only at light 9), and a stone row under the front glass closes the gap an item pushed down along the wall slipped out of.
