Grand Herbalist & Small Manisi Plant

[Barlu]

Did some digging here on the forums without much luck. Anyone that has farmed a few know the spawn % on Grand Herbalist and what a realistic drop % is on the small manisi plant?

Wiki says 20% spawn and 2% drop rate. Trying to get a feel for whether it would be worth camping. 2% drop rate would probably be a no. Thank you!
