Pick a crop, click your ring, stack mutations — see income per second and per harvest. Click the rings to set placement (7× / 13× / 19×).
Total income = base value × mutation stack × ring multiplier × quantity. The further a crop sits from the centre, the bigger the ring multiplier (Inner 7×, Middle 13×, Outer 19×). Since Update 6, multiple mutations on one crop multiply together. Values are labelled by source — verified in-game, community-reported, or pending.
