Methodology & Calculation Methods
Transparent methodology for calculating Grow a Garden trading values, handling outliers, and addressing community discrepancies about event multipliers.
Our Formula
Median Value = P50(CleanedSamples)
Where CleanedSamples exclude the top and bottom 10% of raw trading data
Step 1: Data Collection
- Gather trading samples from multiple sources
- Include Discord, Trade Hub, and in-game data
- Timestamp all samples for freshness tracking
Step 2: Sample Cleaning
- Remove bottom 10% (P10) - suspicious low values
- Remove top 10% (P90) - suspicious high values
- Keep middle 80% for reliable calculations
Step 3: Statistical Analysis
Eclipse Event Multiplier Discrepancy
The community has different opinions about Eclipse event multipliers. Some sites show ×15, others show ×20. Our testing indicates ×20 based on in-game sell price calculations.
Our Stance: ×20 Multiplier
- Based on direct in-game testing
- Consistent with sell price calculations
- Verified by multiple community members
Why Discrepancies Exist
- Game updates change multipliers over time
- No official documentation from developers
- Different testing methodologies across sites
Our Testing Method
We test by comparing actual sell prices during Eclipse events vs normal times, using the same crops with identical weights and mutations.
Sell Price Formula
Weight Scaling
Quadratic scaling: (actualWeight/baseWeight)². Heavier crops are exponentially more valuable.
Growth Mutations
Choose one growth mutation. Multiplies directly: Rainbow (×5), Corrupted (×50), etc.
Env/Event Mutations
Multiple allowed. Uses "extra parts" method: 1 + Σ(multiplier - 1) to avoid double-counting.

This is an unofficial fan-made tool. We are not affiliated with Grow a Garden or its developers. All values are community-driven estimates based on player trading activity, not official pricing.
Values should be used as rough guidelines only. Actual trading values may vary significantly based on market conditions, player preferences, and game updates. Always negotiate and confirm values with trading partners directly.
