How to level herbalism from 160-450 quickest?

[Omgowned]

How would I go about doing this? With the current profiles it seems way to long and annoying(the ones I have been using.)

I would like it done by tonight so I can bot in Wintergrasp..

Since I have the following GOLD MINE professions

Hunter:
450 Mining, 160 Herbalism

Pally:
450 JewelCrafting, 450 Inscription

Suck it up and do it manually. That's the fastest way.
wow-professions.com has a guide on all professions for powerleveling.

More importantly, be grateful that GB is automating the "slow" process for you.

I do it manually until 300, and then use GB up to 450.
Flying mount ftw.

1~300, GB is slow cause of ground mounts.
