On Donut SMP, a farm is only good if the numbers work.

We tested two money routes:

• 80-module bonemeal farm
• Chest auto crafter using spruce logs

One made about 9M per hour.

The other lost about 26M.

The difference was not redstone skill. It was market math.

If you build farms without checking input cost, output price, raid risk, and server performance, you are not farming money. You are donating it.

↖ Donut SMP Money Farm Comparison

Best pick right now: bonemeal farm.

Chest crafting can print money, but only when chest price > 2 × log price.

↖ Why Bonemeal Farms Work on Donut SMP

The bonemeal setup wins because bone blocks have strong demand and the output sells cleanly.

The tested build used 80 modules, scaled from a 20-module design.

↖ Bonemeal Farm Test Data

This is a real profit farm, but it is not a starter build.

If your PC struggles with redstone, do not start at 80 modules. Start at 20. Test. Then scale.

↖ Best Bonemeal Farm Setup

The farm needs two things:

1. Stable output

2. A hidden location

If either fails, you lose time or get raided.

↖ Recommended Setup

Do not build this near surface bases.

A farm that makes 9M/hour is worth hiding properly.

↖ Bonemeal Farm Build Checklist

Most bad bonemeal farms fail because one small piece is missing.

Check this before AFKing:

Important detail: the signal dispenser matters. If it controls the next modules, one bad dispenser can kill output across the whole line.

If output looks uneven, check:

• Missing water
• Empty dispenser
• Hopper backup
• Bad timing
• Server lag
• Chunk loading

Fix the small version before scaling.

↖ Best Scaling Plan for Bonemeal Farms

Do not jump straight to 80 modules unless you know your setup can handle it.

Best practical size for most players: 40 modules.

It is strong enough to make real money and less likely to melt your client.

↖ Chest Auto Crafter: Why It Lost Money

The chest crafter worked mechanically.

The market killed it.

The setup converted spruce logs → planks → chests using auto crafters. The problem was input cost vs sell price.

↖ Chest Crafter Test Data

This is the key lesson:

A working machine can still lose money.

↖ Chest Auto Crafter Profit Formula

A chest needs 8 planks.

One spruce log gives 4 planks.

So one chest needs 2 logs.

That means:

Minimum profitable chest price = 2 × log price

If logs cost 85, your material cost per chest is 170.

If chests sell for 125, you lose 45 per chest before storage or market delays.

That is not bad luck. That is bad buying.

↖ When Chest Crafters Are Worth Running

Chest auto crafters are not bad. They are just market-sensitive.

Run them only when the math is green.

Chest crafters are closer to market flipping than farming.

If you ignore prices, the farm becomes a loss printer.

↖ Bonemeal Farm vs Chest Auto Crafter

Build bonemeal for stable income.

Build chest crafter only if you are watching the market.

↖ Best Donut SMP Farm Strategy

Use this loop:

Check price → build small → test output → scale only if profitable.

↖ Practical Rules

If you find chest prices below material cost, stop crafting.

If your bonemeal farm lags at 20 modules, do not build 80.

If your farm is easy to find, move before it gets raided.

↖ Best Recommendation by Player Stage

Best all-around pick:

40-module bonemeal farm at deep slate level with shulker storage and overflow protection.

It gives strong income without the worst lag of an 80-module build.

FAQ

↖ Is a bonemeal farm worth it on Donut SMP?

Yes. The tested 80-module bonemeal farm made about 9M/hour from 10 shulker boxes of bone blocks. It is worth building if you can handle the size and performance load.

↖ How many bonemeal modules should we build first?

Start with 20 modules. If timing, storage, and lag are stable, scale to 40. Only go to 80 modules if your PC and storage can handle it.

↖ Why did the chest auto crafter lose money?

Because the input cost was higher than the output value. Around 600K spruce logs cost about 54M, but the chests sold for only about 28M, causing a ~26M loss.

↖ What chest price is needed for profit?

Use this rule:

Chest price must be higher than 2 × log price.

If spruce logs cost 85, each chest costs 170 in materials. You need to sell above 170 to profit.

↖ Are chest auto crafters still good?

Yes, but only during price spikes. If logs are cheap and chest demand is high, they work. If chest prices crash, stop crafting.

↖ Where should we build money farms on Donut SMP?

Build deep underground, preferably near deep slate level, far from busy areas. Use hidden entrances and avoid obvious surface markers.

↖ What is the biggest mistake with Donut SMP money farms?

Scaling before testing. A farm that loses money at small scale will lose more at large scale.

↖ Which farm should we build first?

Build a 20-module bonemeal farm first. It is safer, easier to test, and more stable than chest crafting.

Summary

The bonemeal farm won the test.

It produced about 9M/hour with an 80-module setup. The main risks are lag, fuel cost, and raid protection.

The chest auto crafter lost about 26M because spruce logs were too expensive and chest prices were too low.

Use the simple rule:

Bonemeal = stable farm.

Chest crafter = market play.

If chest price is below 2 × log price, do not craft.

If bonemeal demand stays strong, scale carefully.

If your setup lags at 20 modules, stop before building bigger.

On Donut SMP, big farms do not make you rich. Profitable farms do.
