How To Get The Rainbow Sack In Grow a Garden In Roblox
You can only obtain the item by opening a Premium Seed Pack. It has a 0.5% chance of dropping. Here is a step-by-step guide on how to get the Rainbow Sack in the game:
- Step 1: You need to obtain the Premium Seed Pack first. To get the Premium Seed Pack for free, you can feed the Venus Flytrap approximately 50 times. You can also purchase a Premium Seed Pack directly with Robux.
- Step 2: Once you have a Premium Seed Pack, go to your inventory. Select the Premium Seed Pack and choose to open it. This will randomly grant items. As mentioned, the Rainbow Sack only has a 0.5% drop chance.
- Step 3: Since the drop rate is low, focus on earning more Premium Seed Packs (Repeat the Venus Flytrap feeding process). This is a grind-heavy process and players have to be patient.
What Does The Rainbow Sack Do?
The Rainbow Sack is a rare item that can increase the crops’ value by 50x. It will make your crops rainbow-colored. These crops glow with vibrant, multi-colored hues and have their selling price multiplied by 50x their regular value.
This will help the player earn Sheckles (in-game currency). This will help the player buy better seeds, gear (e.g., Advanced Sprinklers), or rare items. Note: For maximum profit, use the Rainbow Sack on multi-harvest crops like strawberries, blueberries, grapes, or tomatoes.
