After completing his quest, players gain access to his farm. The soil only allows for growing mushrooms however, and Bob's Uncle will receive 50% of the yields.
Compared to growing 50 shroom seeds on player's farm, it's slightly faster when growing on Bob's Uncle farm (3.125 and 6.25 hours with 4 plots). The farm acts as a stacking farming perk, offers much convenience for less farming XP (1,250 and 7,500 XP with traditional way) and half of the yields. The XP reduction of Red Mushroom is negligible at high level of farming however.
- He forgets to collect his 50% tax, but this seems to happen with Red Mushroom only. The loot dialogue says 200 - 575 like it's supposed to be, but it's actually 400 - 1,150.
