Blackout is a high multiplier (×95). Put it on a high base-value crop (this site uses Sunflower, 50,138₡ at 8.55 kg, as the reference) and add weight² before chasing extra small mutations.
💰 Worked Examples: Blackout on a Sunflower
Numbers use the site formula Base × (Weight/BaseWeight)² × Growth × (1 + Σmutations − count) and Sunflower's listed base. Plug a live crop into the Grow a Garden calculator for other weights.
🔗 Stacking & Best Combos
Once Blackout is on a fruit it follows the additive rule with other non-growth mutations: 1 + Σ(multipliers) − count. Gold (×20) or Rainbow (×50) then multiplies that total. Cleaning Spray (Gear Shop, listed on stock) can strip mutations if you need to rebuild a fusion.
