Grandmaster Sprinkler

The Grandmaster Sprinkler is the top tier of the sprinkler line — a prismatic gear from the Gear Shop, added in the Cooking Update. Within its radius, every newly planted crop gains massively increased size, higher mutation odds, and faster growth at once, making it the single most powerful planting buff a player can self-trigger.

The headline number is the 4x crop-size multiplier, and crucially it stacks additively as +3 when layered with other sprinkler types — so combining it with lesser sprinklers pushes size scaling even higher rather than overwriting it. Because size and mutation both feed final sell value, a crop grown entirely inside this field can be worth multiples of the same seed grown bare. The catch is the clock: the boost lasts only 10 minutes, so it rewards preparation.

To capitalize, pre-stage a full batch of your most valuable seeds and plant them all the instant the sprinkler activates, layer it with secondary sprinklers for the additive size bonus, and park boosting pets nearby — the sprinkler raises a pet's effective weight by 4 kg, strengthening its passive even though it does not shorten ability cooldowns.
