The Mushroom Sprinkler Method is a community money farm where you stack as many sprinklers as you can over a dense bed of mushroom seeds so the mushrooms grow oversized and sell for far more — but it’s an unofficial trick, results vary, and at least one recent run suggests it may have been nerfed.
The idea behind the mushroom sprinkler method in Grow a Garden 2 is simple enough to explain in a sentence: over-water a tight patch of mushrooms with a pile of sprinklers, let them balloon in size, then sell them for a fat stack of Sheckles. The catch is that almost nothing about it is officially documented. It’s a player-discovered trick — often called a sprinkler glitch — and the numbers behind it shift from run to run, so treat everything below as the current community read rather than confirmed mechanics.
What the mushroom sprinkler money farm actually is
At its core this is a money-farming setup, not an official feature. You blanket a plot with sprinklers, grow a dense field of mushrooms inside that coverage, and bank on the stacked watering pushing the mushrooms to an oversized harvest worth far more than a normal one. Mushrooms get used for this because they have decent base value and turn over quickly, which makes them friendly to repeated cycles.
What’s not settled is whether this is an intended mechanic or a bug. Players widely describe it as a glitch or exploit, and there’s no official stance published on it — meaning it could be patched, nerfed, or left alone at any point. The exact size multiplier, the sprinkler count you actually need, and even whether mushrooms still respond to the trick after recent updates are all unverified. A recent showcase run is the clearest warning sign here: a fully grown field topped out at only a 30 kg mushroom, underwhelming enough that players openly wondered whether it had just been nerfed.
Gear and seeds to line up first
You don’t need anything exotic, but you do need volume. The essentials are an empty plot you control (so nobody else harvests your mushrooms), a stack of sprinklers across as many tiers as you can afford, a big pile of mushroom seeds — players show inventories running from dozens up past 100 for a single cycle — and ideally your best watering can to push everything to fully watered fast. Higher-rarity sprinklers reportedly give bigger size boosts and wider range, so a few strong ones mixed into the cluster help more than a wall of weak ones.
The figures below are worth knowing, but read them as rough, unverified guidance rather than gospel.
| Sprinkler | Approx. cost (Sheckles / Robux) | Duration | Notes |
|---|---|---|---|
| Basic | 25,000 / 79 | 5 min | Shows up most often (~33% stock chance) |
| Advanced | 50,000 / 99 | 5 min | Mid roll (~14% stock chance) |
| Godly | 120,000 / 149 | 5 min | Rarer pull (~9% stock chance) |
| Master | 10,000,000 / 199 | 10 min | Larger boost, ~1% stock chance |
| Grandmaster | 1,000,000,000 / 279 | 10 min | Top tier, ~0.5% stock chance |
Sprinklers turn up in the Gear Shop and from a Sprinkler Merchant. The community also claims a 100 sprinkler cap per plot; that’s unconfirmed, but it’s a reasonable ceiling to assume when you’re packing a field.
How to run the mushroom sprinkler method in Grow a Garden 2
Lay your sprinklers down first
On an empty plot you control, place all your sprinklers before planting a single seed — this ordering is the whole trick.
Stack every sprinkler tier together
One showcase loadout used five common, five uncommon, three rare, one legendary, and one super sprinkler, clustered tight so their watering ranges overlap.
Spam mushroom seeds across the covered tiles
Plant mushrooms on every tile the sprinklers reach, dropping them by the dozen so nothing sits outside the coverage.
Let the mushrooms grow fully
Wait until every mushroom hits its fully grown state — with stacked sprinklers and a strong watering can this can take only a short while.
Apply mutations, then harvest and sell
Once they’re grown, stack mutations like wet, chilled, or shocked onto the mushrooms before selling for the size-boosted payout.
Place every sprinkler before you plant or harvest a thing — sprinklers-then-seeds is the one piece of ordering every version of this method agrees on.

The leave-and-rejoin twist and why payouts swing
Here’s where the method splits in two. The on-screen run above plants, waits, and harvests in one sitting — and its big mushroom came out at just 30 kg, a result that read more like a nerf than a jackpot. Community write-ups, on the other hand, insert an extra move the demo never shows: once everything is fully grown, you leave the server and immediately rejoin, and players report the mushrooms coming back visibly larger — often around 2–3× — than a normal harvest.
Whether that rejoin step is doing real work or is just folklore isn’t settled, and there’s no consensus on how long to wait. Some guidance suggests a 5–10 minute offline window for tree crops, while mushroom runs usually just bounce out and back in the moment the field finishes growing. Exact Sheckles per mushroom aren’t documented either, so the honest summary is this: the no-rejoin version underwhelmed in at least one recent run, the rejoin version is what most claimed-2–3× results lean on, and all of it traces back to player footage rather than confirmed numbers.
Where to take your mushroom farming next
If the payouts feel shaky, the natural next questions are about alternatives. There’s a live debate over the best crops for sprinkler farming — mushrooms versus strawberries versus high-value tree fruit for Sheckles per hour using the same stacking — and plenty of interest in getting high-tier sprinklers fast, mostly by grinding the Gear Shop and events like the Mole for rare, legendary, master, and super sprinklers.
It’s also worth having a non-glitch fallback ready. Optimized mushroom layouts with mutation stacking — wet, chilled, shocked — can pull strong income on their own, which matters a lot if the sprinkler trick gets patched out from under you.
Frequently Asked Questions
Is the mushroom sprinkler method a glitch or an intended mechanic?
It’s widely treated as a glitch or exploit rather than a confirmed feature, and there’s no official stance published on it. Until that changes, assume it could be patched at any time.
Did Grow a Garden 2 nerf the mushroom sprinkler trick?
Possibly. A recent reported run produced a mushroom of only 30 kg, weak enough that players suspected a nerf — but there’s no official confirmation either way, so it’s an open question, not a settled fact.
Do you have to leave and rejoin for it to work?
Community guides add a leave-and-rejoin step and credit it with the big 2–3× size jumps, while the on-screen run skipped it and underwhelmed. There’s no consensus on the wait time, and the rejoin’s real effect is unverified — but most of the standout results lean on it.
How many sprinklers do you need, and is there a cap per plot?
There’s no proven number — more and higher-rarity sprinklers reportedly mean bigger boosts, and the goal is full coverage with no gaps. The community claims a 100 sprinkler cap per plot, but that figure isn’t confirmed.
Does the sprinkler trick work on other crops like strawberries or bamboo?
The wider glitch is reported to work on strawberries but was found “busted” on bamboo. Mushrooms haven’t been explicitly tested in that comparison, so whether they behave more like one or the other isn’t confirmed.

Should you place sprinklers before or after harvesting?
Place them before — sprinklers go down first, then seeds, while the plants can still benefit from the size and growth boost. Setting them up after the fact is the most common way to waste a run.
