Hey so I'm 92 herblore, I grinded it the first like 2 weeks (was in the top 10 ranked at the time for a while if I remember correctly, as I haven't trained it in like 3 weeks). Anyway, a lot of the times you end up with random herbs, whether its from slayer or bank keys. If you bring me the supplies I will gladly make you the pots free of charge. Ex. if you somehow end up with 10 dwarf weed in your bank, just go buy 10 wine of zammy for 25k and boom you got 10 range pots for 25k.
