Nice
@IAmKrazy2 welcome back.
Yes you can stuff a decent chunk in. Airflow does help I had a load this morning out of my scs. Good results. The tighter you pack it the darker the plant becomes while extracting. Most likely due to the limited airflow allowing a longer roast before cooling. I'm going to throw a half load in now.
I agree with krazy, I have been getting 2~3 draws per heat cycle. Taking 2~3 heat cycles for extraction. It is the among the fastest conduction vapes I have used.
I loaded a half chamber of scs ground herb loosely. 1 heat cycle 2 draws complete extraction.
Addition. The only negitive I have if you could call it that is. The lighter does consume some butane. 2 days, refilled once and down a ½ tank on that fill today. Three flames =power and butane usage.
