Data sources & methodology
How The Garden Codex gathers, verifies, and labels every value on this site.
Every value is traceable to a named source, labelled with a confidence level, and correctable by the community. No decompiled data, no GAG1 data, no automation tools.
Last calibrated: 2026-06-28.
- In-game testing — direct verification by our editors; the gold standard.
- TheGamer — community-verified base resale prices; our primary floor-value baseline.
- growagarden2wiki.net — independent wiki; matches TheGamer within 5%.
- Community calculator bundle— the in-game calculator's
sellValuefield; stored ascalc_sell_value_sheckles. - Single-source reports — flagged Unconfirmed until cross-verified.
Two independent sources agreeing upgrades an entry to Cross-verified; an official source upgrades it to Official.
Recalibration history (2026-06-21 / 2026-06-22)
2026-06-21: Removed the legacy base_value_shecklesfield for 27 of 30 crops — it tracked a community ranking-page number, not the in-game base resale price (ratios ranged 5–250×). Kept for carrot / tulip / bamboo (≤ 2× ratio). Full notes live in each data file's _meta.
2026-06-22 fix: Removed the MULTI_HARVEST_BASELINE (×8) constant introduced in fix-19. It was an invented harvest multiplier — the community-consensus 5–15 range was speculation, and the A bundle calculator does not fold a harvest count into its profit formula; it lets users input quantity instead. Profit margin is now calculated using the same formula as the community calculator bundle: sellValue × weight² × mutationMult − seedCost. Default parameters: weight = 1 kg, no mutations, quantity = 1. Most crops show negative profit at this baseline because they need higher weight, mutations, or multi-harvest lifetime to be worthwhile. Use the calculator to model real scenarios.
2026-06-22 values-table simplification: The /values table only shows accurate facts (sell value, seed cost, grow time, rarity). Profit / ROI columns were removed because they are misleading at default parameters for multi-harvest and speculative crops, and there is no single canonical lifetime value. Profit calculation is done in the calculator where the user supplies real parameters. The Grow column shows a ↑ suffix for multi-harvest crops and ⚠ for speculative crops as a lightweight type hint.
2026-06-22 badges recalibration: Badges are sourced directly from the official Roblox Badges API (universe 10200395747). Statistics are real-time as of fetch date (2026-06-22). All 23 badges are now labelled Official — the previously community-reported awarded_count and win_rate values have been replaced with authoritative Roblox statistics.
Official | Official. Confirmed by the Roblox API, patch notes, or an official announcement. |
|---|---|
Cross-verified | Cross-verified. Multiple independent community sources report matching values. |
Likely | Likely. One community source; not yet cross-verified. |
Unconfirmed | Unconfirmed. Speculation, datamine, or no source evidence. |
Priority targets
- P0 (urgent): Electric, Frozen (280%+ source discrepancy); Shocked (zero independent cross-verification)
- P1 (moderate discrepancy): Bloodlit, Rainbow
- P2 (small discrepancy): Starstruck
Testing protocol
- Wait for the relevant weather event (Lightning → Electric, Snowfall → Frozen, Starfall → Starstruck, Blood Moon → Bloodlit, Rainbow weather → Rainbow)
- Plant a crop with a known base sell value (e.g. Apple = 12 Sheckles)
- Record the crop's exact weight in kg
- Apply only ONE mutation (avoid stacking to isolate the multiplier)
- Sell the crop and record the final sell price
- Calculate:
multiplier = sell_price / (base_value × weight²) - Collect ≥5 samples per mutation across different servers
- Report results via our contact email with screenshots
Why this matters
Single-source data (including the calculator bundle A) can be stale after game updates. Multi-source consensus is our current best proxy until in-game verification confirms the values.
- Mutation multipliers. Adopted values come from cross-source Council arbitration (2026-06-28), not from a single primary. Major disagreements: Rainbow (Site A 25 / Eurogamer-media 30 adopted / deprecated C 40), Electric (Site A 70 / Eurogamer-media 25 adopted / deprecated C 80), Frozen (Site A 40 / Eurogamer-media 14 adopted / deprecated C 4). See /insights/mutation-multipliers-complete for the full table.
- Pineapple buy price. 10,000 vs 30,000 Sheckles.
- Coconut buy price. 140,000 vs 70,000 Sheckles.
