Seed price is the cost of starting or adding a plant when that seed appears through the reviewed shop route. Average value is the published unmutated Sell Stand value for one crop at its listed average weight. Comparing those two numbers directly does not produce profit because repeat harvests, growth time, crop count, weight and mutations still matter.
For a buying decision, start with this page to identify the crop, then use the Seed Shop audit for refresh and wait-time evidence. Use the crop profit calculator only after entering your own harvest count, cycle time and mutation scenario.
The listed chance is a community-reported per-refresh field, not a guarantee that the item is currently visible. The live server shop remains the final check. A crop outside the shop snapshot can come from a pack, event, testing route or a later update; this database does not guess which explanation applies.
For pack-exclusive crops, move to the seed-pack odds calculator. For the published sell metric and all ten historical discrepancies, open the complete crop values audit.
