If you’re playing Grow a Garden on Roblox and aiming to upgrade your farm, one item you absolutely need to know about is the Rainbow Sack which is one of the new item in the Newest Update. It’s one of the rarest and most powerful items added in the latest update. In this guide, we’ll explain exactly what the Rainbow Sack does, how to get it, and why you should grab it before it’s gone.


What is the Rainbow Sack?

The Rainbow Sack is a special item that lets you grow rainbow crops 100% of the time. Normally, rainbow crops are extremely rare and only show up occasionally when planting. However, when you place down a Rainbow Sack on your farm, the crops that grow from that spot will always be rainbow versions.

These rainbow crops are much more valuable than regular ones, making the Rainbow Sack an incredibly useful tool for boosting your garden’s profit and looks. Even though the item doesn’t have an official in-game description, testers have confirmed its effects: permanent rainbow crops wherever it’s used.

How to Get the Rainbow Sack

Getting your hands on a Rainbow Sack takes some effort and luck. Here’s the full process:

  1. Feed the Angry Plant: Focus on feeding the Angry Plant (also known as the Venus Fly Trap) 50 times.
  2. Earn a Premium Seed Pack: After 50 successful feedings, you will be rewarded with a free Premium Seed Pack.
  3. Open the Premium Seed Pack: The Rainbow Sack can only be found inside a Premium Seed Pack. However, the odds are low — you have about a 0.5% chance to pull it.
  4. Keep Trying: Since the drop rate is very low, you might need to open multiple Premium Seed Packs to get the Rainbow Sack. Keep grinding if you want it before the update ends!

Important note: Rainbow Sacks will become unobtainable once the update is over, so if you want one, start grinding now before it’s too late. Here’s the Full Guide on the Angry Plant Grow a Garden.

Why the Rainbow Sack is Worth It
