In every batch of Tangiers i have ever opened i have never come across even one stem. Only gigantic leaves. Never a stem. I get way more stems in Starbuzz.
Acclimation doesn't exactly have to be for a whole day, it can be shorter, but i do acclimate it for about that long. I probably have more free time then you do though.
. Spreading it out over a large surface area will make it acclimate quicker, but fluctuations in humidity will mess with it.
And it also does not have to be smoked using a phunnel. I know many people that just use a standard style bowl.
I am actually not able to smoke Tangiers in the winter season, as my temperature and weather change so abruptly. It is almost always in a constant state of humidity shock.
The mod does lessen the amount of shisha in the bowl, but i have never used it with Tangiers, and have been told not to. But i think it's worth a try.
