Quick answer: Buy the Super Sprinkler from Molly's Gear Shop for $100,000 Shillings (or 149 Robux), equip it from your hotbar, and left-click to place it in your garden. It activates immediately and runs for 15 minutes, increasing both growth speed and fruit size for every plant within its range.

What the Super Sprinkler Does
The Super Sprinkler is a single-use, placeable tool that waters nearby crops automatically for 15 minutes after you set it down. During that window, it accelerates plant growth and enlarges the fruit that those plants produce — bigger fruit sells for more Shillings. It outperforms both the Basic Sprinkler (5-minute duration, Uncommon rarity) and the Turbo Sprinkler (10-minute duration, Epic rarity), making it the strongest sprinkler tier currently in Garden Horizons.
Because it carries Legendary rarity — the only item in the game at that tier — it appears in the shop far less often than other gear. You may need to check back several times before it shows up.

Buying the Super Sprinkler from Molly's Gear Shop
Step 1: Head to Molly's Gear Shop. The quickest route is to tap the Seeds button at the top of your screen to teleport near Bill's seed stall, then turn left. You'll spot Molly's stall under a white-and-green awning near the fountain area.
Step 2: Press the E key to interact with Molly and open the shop interface. Scroll to the bottom of the inventory list. If the Super Sprinkler is in stock, it will be listed at $100,000 Shillings.
Step 3: Click Buy to purchase it with Shillings. If you'd rather skip saving up in-game currency, you can also buy it outright for 149 Robux.
The shop's stock rotates every five minutes, and Legendary items have the lowest appearance rate. If you don't see the Super Sprinkler, close the menu, wait for the next rotation, and check again. Joining the Garden Horizons stock-tracking Discord server and enabling notifications can save you from camping the shop manually.

Placing and Activating the Super Sprinkler
Step 1: Open your backpack and drag the Super Sprinkler onto your hotbar. Press the corresponding number key to equip it.
Step 2: Walk into your garden and position yourself where you want the sprinkler. A green highlighted zone will appear on the ground showing the tool's effective radius.
Step 3: Left-click to place the sprinkler. It starts working the instant it hits the ground — no additional activation is needed.
The 15-minute timer begins immediately. Once it's down, harvest any ripe crops inside the green zone right away so the next growth cycle benefits from the size boost. You can also plant fresh seeds around the sprinkler before the timer expires to give an entirely new batch the enlarged-fruit effect.

Super Sprinkler Compared to Other Gear
| Item | Cost (Shillings) | Rarity | Duration |
|---|---|---|---|
| Watering Can | 5,000 | Common | Immediate |
| Basic Sprinkler | 15,000 | Uncommon | 5 min |
| Harvest Bell | 35,000 | Rare | Immediate |
| Turbo Sprinkler | 60,000 | Epic | 10 min |
| Favorite Tool | 80,000 | Epic | Immediate |
| Super Sprinkler | 100,000 | Legendary | 15 min |
The Watering Can gives a quick one-time speed boost, and the Harvest Bell lets you collect every fruit from a plant in a single action. The Favorite Tool locks a fruit so it won't be accidentally sold. Among the three sprinkler tiers, the Super Sprinkler offers the longest active window and the largest growth and size multiplier.
Maximizing Profit with the Super Sprinkler
Because the Super Sprinkler is a one-time-use item at a steep price, placement matters. Avoid wasting it on low-value crops like carrots or onions. Instead, cluster your highest-earning plants — check the game's seed tier rankings — into a tight group before you set the sprinkler down. Positioning it at the center of that cluster ensures every high-tier plant falls inside the green radius.
Timing your harvest cycle is equally important. Clear all ripe fruit the moment you place the sprinkler so the next round of growth happens entirely under the 15-minute buff. If you have spare seeds for top-tier plants, drop them into open plots within range before the timer runs out to squeeze extra value from a single sprinkler.
At the late-game stage, where individual harvests can return well over 100,000 Shillings when mutations and traits align, the Super Sprinkler pays for itself in a single cycle if you pair it with the right crops. Treat it as an investment rather than a convenience item, and time your purchases around when your garden is fully stocked with premium seeds.

The Super Sprinkler is straightforward to use but easy to waste. Stock-watch the Gear Shop, save your Shillings, and deploy it only when your most valuable plants are ready for a growth cycle. One well-placed sprinkler can turn a 100,000-Shilling expense into a multi-harvest windfall.
