Black Leaf Violet Glass Jar Review
If you’ve been storing your cannabis in a plastic bag or a regular mason jar, you’re probably losing potency, flavor, and freshness faster than you realize. This Black Leaf violet glass jar review covers everything you need to know about one of the best herb storage containers on the market — a UV-blocking violet glass jar with a built-in digital thermometer and hygrometer to keep your herbs in peak condition.
What Is the Black Leaf Violet Glass Jar?
The Black Leaf violet glass jar is a premium herb storage container made from specialized violet-tinted borosilicate glass. Unlike clear or green glass, violet glass blocks the full spectrum of visible light while allowing beneficial UV-A and infrared light to pass through. This unique property makes it ideal for violet glass herb storage, preserving the terpenes, cannabinoids, and essential oils that give cannabis its character.
Black Leaf kindly sent over their violet glass jar for this review, and I’ve been testing it for several weeks to give you an honest assessment. The jar comes with a built-in digital display showing real-time temperature and humidity — two of the most critical factors in keeping your herbs fresh.
5 Key Benefits of the Black Leaf Violet Glass Jar
1. UV Light Protection for Preserved Potency
UV light is one of the biggest enemies of cannabis quality. It degrades THC into CBN, dulls terpenes, and accelerates the breakdown of delicate plant compounds. The violet glass used in this Black Leaf glass jar filters out harmful UV-B and UV-C rays while letting in only beneficial wavelengths. Studies on violet glass (also called miron glass) show it can significantly slow the degradation of organic materials stored inside.
