Blüten trocknen & curen: Was Physik und Studien wirklich zeigen

ℹ️ Journalistic educational video on the legal situation according to the KCanG (German Cannabis Act): no instructions, no encouragement to cultivate or consume, no advertising. For adults 18 and over only. Between harvest and finished flower, up to 75% of the weight is lost – and often a large part of the aroma along with it. In this deep dive, we look at what happens physically and chemically during drying and curing: relative humidity, water activity and dew point, why heat destroys terpenes (in one study, only 29.9% remained at 90°C instead of 82.1%), and what "case hardening" means. We also address the 7 most common mistakes and myths, why the KCanG counts the dry weight, why flowers from pharmacies are dried according to completely different rules – and whether curing cabinets are really worth it. To help you understand the reliability of a statement, the video uses an evidence traffic light: Green = supported by studies or standards, Yellow = plausible or manufacturer's information, Red = myth. ⏱️ CHAPTERS 0:00 The 2 weeks that decide everything 1:04 Why dry at all? 2:34 The physics: Humidity, water activity, dew point 5:25 The chemistry: Terpenes, THCA, and chlorophyll 8:09 Post-harvest in practice: Climate, air, duration 13:32 Curing: The phase after drying 15:59 The 7 most common mistakes and myths 18:00 The legal catch: Dry weight is what counts 19:03 Pharmacy: How medicinal flowers are dried 23:18 Curing cabinets reviewed 27:48 Conclusion: 8 key takeaways ℹ️ CONTEXT This video is journalistic and informative reporting.
