The code list for Plant Brainrot Simulator is sitting at over 40 active codes right now, with no confirmed expirations. That's unusual for a Roblox game, and if you haven't redeemed yet, you're missing out on a pile of free crystals, potions, and fruits.
What the game is actually about
Plant Brainrot Simulator drops you into a garden defense loop where you're growing plants and smacking down waves of brainrot enemies. You collect money from kills, upgrade your plants, and eventually rebirth for permanent stat bonuses that reset your progress but make the next run faster. The codes cut down the early grind significantly, especially if you're starting fresh.

Where codes come from and how fast they drop
Rainbow Isle Studio releases new codes through their Discord server, usually tied to update milestones and Discord member count targets. The naming makes the pattern obvious: UPDATE10 dropped with the tenth major patch, while 8KDC, 9KDC1, and 10KDC2 tracked Discord growth. Milestone codes like 1KLIKE and 5KLIKE also appear when the game hits like count targets.
More codes are coming. The jump from UPDATE9 to UPDATE10 happened recently, so an UPDATE11 announcement is probably next.
