Cobblestone farms on Donut SMP are one of those ideas that sound boring until you actually build one. Cobble is easy to understand, always useful, and usually has buyers. But once TNT cost enters the equation, the farm becomes less about how much cobble can we make? and more about are we selling it at the right price?

After testing a large cobblestone farm setup, the answer is clear: cobble farms can be meta, but only when cobblestone prices are high and TNT is cheap enough. If the market is bad, this farm can lose money even while producing a ton of blocks.

↖ Quick Verdict

For most players, a cobblestone farm is not a guaranteed money printer. It is a market-dependent farm.

If you are low on money, this probably should not be your first big farm. If you already have capital, storage, and a good schematic, it can be worth building.

↖ Our Test Results

In our test, the farm worked well mechanically. It produced a large amount of cobblestone in one hour and filled multiple storage sections. The problem was not the farm design. The problem was the market.

This is the part a lot of players miss: high output does not always mean high profit. At 26 per cobble, the farm simply did not earn enough to beat the TNT cost.

↖ Why TNT Cost Matters So Much

A TNT-based cobblestone farm burns money while it runs. Every blast has to be paid for, so your profit depends on the gap between cobble income and TNT expense.

If TNT is expensive, the farm needs a higher cobble price to survive. If TNT is cheap, you have more room to profit.

If you check the market and cobble is selling low, do not force the farm. Let it sit. A silent farm is better than an active farm losing millions.

↖ Donut SMP Build Notes

This farm is not hard because cobblestone is complicated. It is hard because the redstone, TNT timing, and storage system all need to work together.

One important Donut SMP detail: hopper behavior may require different item counts than a normal setup. In some hopper/dropper parts, you may need two stacks of items instead of a smaller amount for the system to work properly.

From experience, the first startup is where most mistakes show up. Do not fill the whole system with TNT immediately. Test it slowly first, unless you enjoy watching your bank account evaporate.

↖ Is It Better Than Other Farms?

Cobblestone farms can compete with other Donut SMP money farms, but they are less stable than low-cost farms.

Cobble farms are best for players who already understand the economy. If you just want steady income, kelp or berries may feel safer. If you like timing the market and scaling output, cobble has real upside.

↖ When Should You Run a Cobblestone Farm?

Before running the farm for a long session, check two things:

1. Cobblestone buy price

2. TNT price

Then do a short test.

A short test is the easiest way to avoid a bad overnight session. If 10 minutes is losing money, one hour will not magically fix it.

↖ FAQ

↖ Are cobblestone farms worth it on Donut SMP?

Yes, but only in the right market. They are worth it when cobblestone prices are high and TNT prices are reasonable.

↖ What cobble price should I look for?

Around 45–50+ each is where the farm starts looking good. Under 30 each, it is usually not worth running.

↖ Why did the farm lose money?

The farm sold cobblestone at about 26 each, which was too low to cover the TNT cost. The farm produced well, but the market price was bad.

↖ How long does the farm take to build?

A large setup can take around 6–8 hours, especially with digging, redstone, TNT systems, and shulker loaders.

↖ Is this a beginner farm?

Not really. The idea is simple, but the actual build is better for players who are comfortable with redstone and storage systems.

↖ Should I run it overnight?

Only after a short profit test. Run it for 10–15 minutes first, sell the cobble, subtract TNT cost, and then decide.

↖ Final Thoughts

Cobblestone farms on Donut SMP are powerful, but they are not always meta. In our test, the farm made plenty of cobble but still lost over a million because the sell price was too low.

The smart play is to treat cobble like a market farm:

• Run it when cobble is expensive.
• Pause it when cobble is cheap.
• Watch TNT prices closely.
• Test before long AFK sessions.
• Make sure storage can keep up.

If cobblestone is selling for 45–50+ each, this farm can be a serious money maker. If it is sitting around 26 each, save your TNT and wait for a better market.
