Thanks chucku, Lo, nr-cole to answer me
30 minutes it's a lot of time, i don't like taste from 12-15 minutes. It's too toasted.
I made some photos of vaporized weed in Iolite and Volcano to compare. See it:
Weed vaporized about 15 minutes in Iolite (190C):
Weed vaporized in Volcano at 185C:
The 2 weeds to compare colours (on the right: Volcano at 185C):
Weed vaporized 8 minutes in Iolite:
This weed has better colour, a little bit darker than weed vaporized in Volcano at 185C, but very similar.
Pic with 3 weeds vaporizations:
up: Iolite 8 minutes, left: Iolite 15 minutes, right: Volcano at 185C (filled 3 bags about 65-70cm)
Pic with vaporized weed with Volcano at 215C-220C (during some minutes until I didn't see more vapour):
It see brown colour, but light brown, lighter than weed in Iolite during 15 minutes and some dark than weed in Iolite during 8 minutes
Pics with weed vaporized in Volcano: on the left, weed vaporized at 215C, on the right, weed vaporized at 185C
Pic with 4 vaporized weeds:
up: Iolite 8 minutes, left: Iolite 15 minutes, right: Volcano at 185C (filled 3 bags about 65-70cm), down: Volcano at 215C
