I think you might find you made a very wise choice with the capsules. I sometimes vape Cannatonic for the high CBD there, usually at my 'standard' 390F. I 'end early' typically, having learned by experience when the THC and CBD are basically exhausted. Still remaining are a lot of heavier components (still making vapor) that contribute to 'couch lock' and similar sedative effects. If I'm using CBD so I can function normally (as is often the case with MMJ types?), that's something I sure don't want. I save the ABV (partially vaped herb) for bedtime when I put it back in and crank the heat up to 420F or something like that to get that benefit.
Make no mistake, the 420F run is more harsh, and lacks some/most of the flavor. A WT here really helps. Even though the production rates are low (high production, dense vapor, being the usual reason to use), the WT can not only cool the vapor some but importantly add water back into it so it doesn't irritate the throat as much.
So, while you should experiment with different techniques for sure to see what suits you best, I suggest you might like vaping a capsule or two of high CBD herb and intentionally 'stopping early' (say when you lose most of the green?) then changing to a new dosing capsule to finish the dosage and let your father finish them (getting the sedative effects) with the WT later on?
Experiment around, you'll sort it out, yer on the right path for sure.
Regards to all.
