In Build A Ring Farm, the seeds get the attention — but the upgrades quietly decide how fast you get rich. The Saw, Sprinkler and Soil Quality each improve every future harvest, which makes them better long-term value than any single seed. This guide explains what each does and the order to buy them. For the full money plan, see how to make money fast.
Why upgrades beat seeds
A seed earns money once per harvest. An upgrade earns you a little extra on every harvest, forever. That difference compounds hard: a maxed Saw running on a full farm of mid-tier crops will usually out-earn a single rare seed you spent everything to afford. The rule of thumb for any reinvestment decision is to ask whether it improves one harvest or all of them — and put your cash behind the “all of them” options first.
The Saw — your top priority
The Saw (often “Saw Yield”) adds roughly +2× per level on top of your ring multiplier, and crucially it applies across your entire farm at once. Because total income is base income × ring × saw × mutation, raising the Saw lifts every plant on every ring simultaneously. That farm-wide effect is why the Saw is almost always the best place to put early and mid-game cash. Keep it levelled as high as you can afford before splurging elsewhere.
The Sprinkler — automation and speed
The Sprinkler improves growth and automates watering, so crops mature faster and you spend less time manually tending the farm. Faster growth means more harvest cycles per minute, which directly multiplies income — and the automation matters even more for offline income, since a smoother-running farm banks more while you’re away. Level the Sprinkler second, right behind the Saw.
Soil Quality — the steady booster
Soil Quality gives a broad boost to your earnings. It’s a solid third priority: not as transformative as the Saw’s farm-wide multiplier, but a reliable, always-on improvement that’s worth buying once your Saw and Sprinkler are in good shape. Think of it as topping up the multiplier stack after the two bigger levers are handled.
The recommended upgrade order
For most players, this order gives the best return on cash:
- Saw Yield — first and ongoing. Farm-wide multiplier; never let it fall far behind.
- Sprinkler Power — second. Faster growth and automation, which compounds the Saw.
- Soil Quality — third. Steady earnings boost across the board.
- Then seeds and rings — once the above are healthy, push into better seeds and unlock the Outer ring.
This isn’t rigid — if you’re sitting on a huge cash pile and a clear seed upgrade is available, take it. But when in doubt, feed the Saw.
Common upgrade mistakes
- Hoarding for a rare seed while upgrades lag. A trillion-dollar seed on an unupgraded farm earns less than a cheaper seed on a maxed-Saw farm.
- Ignoring the Sprinkler. Slow growth throttles everything, including offline income.
- Spreading cash evenly. Push one upgrade meaningfully ahead rather than nudging all three a little.
How far ahead should the Saw be?
There’s no hard cap on how much to favour the Saw, but a useful guideline is to keep it levelled to the point where the next level costs noticeably more than a meaningful seed or ring upgrade — then switch focus. Because the Saw multiplies your entire farm, falling behind on it quietly caps everything you plant. If you ever feel like your income has plateaued despite better seeds, an underlevelled Saw is the usual culprit. Check its next-level cost against your per-cycle income: if you can afford it without starving your replanting, buy it.
Tie it together with layout and the calculator
Upgrades and layout work as a pair: a high Saw multiplies whatever you’ve planted, so it pays off most when your farm layout already has the right crops on the right rings. Before a big purchase, run the numbers in the calculator to see how much an upgrade-boosted harvest is really worth. Get the Saw, Sprinkler and Soil Quality humming and every seed you plant afterward earns more — that’s the quiet engine behind every rich Build A Ring Farm save.
