I don't think the orientation when drying changes how fast they dry. Gravity doesn't pull the water out of the plant. The water first transpires rom the leaves while the plant is living, and then it just evaporates naturally. Unrestricted airflow, air movement, low humidity, and heat are the only things that will make it dry faster.
You know you're high when you wonder why moms everywhere choose Lysol when to normal squares it's no wonder. And if a Woolite Pod commercial somehow makes you think of sex.
