Overview
The Grandmaster Sprinkler is a prismatic gear obtainable from the Gear Shop. It was added in the Cooking Update. Upon using this, every new plant in the radius of the sprinkler will have massively increased Crop size, Mutation chances, faster growth speed, and boosting pets. Specifically, crops receive a 4× size multiplier (+3 when stacking additively with other sprinkler types). Sprinkler lasts for 10 minutes. The boost on pets does not lower the pet's ability cooldown but increases the passive by effectively increasing the pet's weight by 4 kg.
Appearance
The Grandmaster Sprinkler has a unique appearance, with light-red and black colors. It does not take the appearance of a circle from a Basic Sprinkler and Advanced Sprinkler. Instead, it has four-line water shooters with two small water shooters on top that exit through the sprinkler, similarly to the Master Sprinkler and Godly Sprinkler. Additionally, it has a gear-like ring going around under the shooters, similar to the Advanced Sprinkler. Like all other sprinklers, its base is black.
Obtainment
The Grandmaster Sprinkler can be purchased in the Gear Shop for 1,000,000,000 Sheckle at a 0.5% chance of coming on stock or for 279 Robux. The Grandmaster Sprinkler has a very low chance to be obtained from the Mole, Pancake Mole and Imp. The Grandmaster Sprinkler could be obtained with a 2.35% chance from Chubby Chipmunk's acorns. The player could obtain the Grandmaster Sprinkler through evolving an Evo III crop in the Seed Stages Event. The player could also use Fall Activities to obtain this gear by completing 50 activities in the Fall Market Event.

What does this mean?
Grow a Garden's in-game currency. A crop's value is its base Sheckle sell value at its average weight — the anchor the game's weight formula scales from. Gear is listed at its documented Sheckle shop cost instead. Both are in-game figures from the community wiki. Values are not comparable across games.

Patch history
This is currently the first and only sprinkler that affects pets. This sprinkler is the only sprinkler that does not have an outline on its icon in the Gear Shop. Instead, the icon is blurred The Grandmaster Sprinkler is the first Prismatic sprinkler. Grandmaster Sprinkler is the second Prismatic Gear, after Levelup Lollipop. The Grandmaster Sprinkler is the sprinkler with the biggest radius, beating the Master Sprinkler. The Grandmaster Sprinkler has a stock schedule, the same with Levelup Lollipop. By placing all kind of sprinklers near a growing plant, as well as using pets with special abilities, such as Moon Cats, plant size can be maximized. Jandel used admin commands to restock three Grandmaster Sprinkler in the Gear Shop during the Admin Abuse War. During the Safari Harvest Event, The Grandmaster Sprinkler's water particles was changed from a red to a rainbow/color-changing variant. This happened with every other Gear Shop sprinkler as well; Basic and Advanced Sprinkler's water particles are a lighter blue, Godly and Master Sprinkler's water particles are a gold-like color. This is the most expensive Sprinkler in the game, costing 1,000,000,000 Sheckle. The second most expensive are Sweet Soaker, Berry Blusher, Flower Froster, Stalk Sprout, Spice Spritzer, and Tropical Mist Sprinklers, all costing 50,000,000 Sheckle. All of these sprinklers costs 950,000,000 Sheckle less than the Grandmaster Sprinkler. On 10 December 2025, this sprinkler naturally stocked 3 times. On 10 January 2026, this sprinkler stocked with Octobloom & Bonanza Bloom at the same time!
