Although it didn't smoke, because the burner flame burned the smoke, it did stink and set off smoke alarms. I had to grab the can with tongs and shake it to redistribute the hulls because the hulls near the top didn't get hot enough.
I am going to experiment using this as a substitute for perlite in mixes with peat moss. First, using tomato seeds.
