Glow Mushroom in Grow a Garden 2

The Glow Mushroom can be obtained from the Ghost Pepper Pack with a 15% chance of obtainment.

Average sell value is 700 Sheckles at 7.0 kg average weight, which makes it ranked 38 of 93 crops by sell value.

Prime window is 4m, and it is multi-harvest, so it keeps producing after the first pick.

Sell value scales with weight, so the honest efficiency measure is value per kilogram. The Glow Mushroom returns about 100 Sheckles per kg. That ranks it 48 of 83 crops for value density.

For reference, the most efficient crop in the game is the Atlantic Giant Pumpkin at roughly 40,000 per kg, and the median across all 83 crops is about 133.

Among Epic crops, 3 sell for more than the Glow Mushroom and 10 sell for less.

The higher-value Epic options are Maple Mushroom (13,000), Mushroom (13,000), Cinnamon Stick (1,200).

The game calculates a fruit's sale price like this:

Price = SellValue × SizeFactor × SizeMultiplier × MutationMultiplier × DecayPenalty × FriendsBonus, rounded down.

The part that matters most is SizeFactor, which is Size raised to the power of 2.5 for almost every crop. That is steeply non-linear: a fruit 50% larger sells for about 176% more, and one at double size sells for roughly 5.7×.

Two crops override it — Mushroom uses 1.9 and Bamboo 1.75, so oversized specimens of those are worth proportionally less than they would be otherwise.

Above a size of 5, diminishing returns kick in and the exponent drops to 1.5. Enormous fruit are still worth more, just not on the same curve.

Decay costs 80% of value at full decay, and each friend on your server adds 10%.
