well uh i was happily suprised when i harvested 16 rannars from 1 seed, i got 5 and 7 and 7 from 3 otehr crops and i dint use any gloves or secatuers

Im going to say 16 is max if someone says different dont believe me.

my max was 17 snaps with super compost and secatures

heard the max was 19 from somewhere.. my best is 17. usually about 7-8 though. =X

I know for sure 19 is, maybe even 21.

My max is 18. Anything above that is just too rare, I've been farming herbs for like 8 months now :?

Max is 19, had it 3 times I think on the way to 99 farming.

i once got 19 snaps, but i used secatures and super compost, i'm not sure it is the max but it migh aswell be.
