The boiling point temperature charts are great, but if the flower doesn't have all those terps and compounds, it doesn't matter what the temp is.
I'm leaning towards vaping the bud as I would smoking... getting the full effect of the actual flower strain. That might mean a temp of about 410, but maybe start at 390 for the first couple hits (for flavor), then keep it at 410-420 for the rest. All subject to change, but I'm trying to keep things as simple as possible.
A lot of people usually prefer this way especially if they are vaping or smoking for recreational use. I thought I would add the information for people that don't like the sedative effects that vaping at high temps can cause. I use it medicinally so I'm usually looking for specific strains that provide the right compounds for what I need. You are right though, it makes it a lot easier when you are just looking to get the full extraction from the bud.
