⏱️ Grow Time Scaling
Grow time scales with target fruit size. The time shown above is the base grow time for a 0.09 kg harvest. If you use sprinklers to grow a heavier fruit, the crop will take proportionally longer to reach full size — a fruit twice as heavy takes roughly twice as long to grow.
Harvest Yield — How Many Fruits Does Firefern Give?
Each Firefern tree produces 4 fruits per harvest cycle. As a multi-harvest plant, Firefern regrows its fruit after each harvest, so you only pay the seed cost once.
At Lush value (900 Shillings per fruit), a full harvest of 4 fruits yields ~3,600 Shillings per cycle at base weight — even more with Sprinkler weight boosts.
Weight & Value
A typical Firefern weighs around 0.09 kg at harvest. Crop weight has a major impact on how much it sells for — the scaling is quadratic, meaning a specimen twice as heavy as average earns roughly four times more at the market.
Lighter harvests will be worth noticeably less than the base value, while an unusually heavy crop can multiply your earnings several times over. Always wait for the heaviest possible harvest before selling, and use our plants value calculator to see exactly what any given weight is worth.
