Ok so far my expereince is not going too well but I am learning and that is the most important thing.

The herbs in my IPA have been sitting there for a day and the IPA isn't evaping much (even with fan), I think I used too much IPA. So for next time should I use as little of IPA as possible so they are just barely covering the herbs? Any tips or pointers?

First suggestion is to use the same thread as before in the future...

Second is to use a shot glass and just use enough alcohol to get your spice dissolved...

When you use too much alcohol you can move it over to something with more surface area like a small bowl or evaporation dish. More surface area = faster evap times.

I usually put my changa evaps under a ceiling fan that has a shelf nearby so that the majority of the wind is coming down from above. That seems to help evap things pretty quick.

Depending on the ISO alcohol %, there will be some water in the mix that takes a bit longer to evap.

Last tip is to have some patience. These things take time and if you try to rush them, you'll just end up smoking alcohol vapors or something. Put it under a fan and go do something else for the day. It's kinda like the saying "A watched pot never boils"... "watched changa never evaps"..
