7 Month Tomato Test Between an Herb Preserve Stash Jar and a Clear Glass Equivalent
The tomato in the clear glass had mold and microbiological growth while Herb Preserve's tomato showed no loss of color or sign of drying out. Imagine the difference it would make for your herb. It can't get much more smoker friendly.

2 Month Chive Test: (from L to R) Herb Preserve Deep Violet, Amber, and Clear Glass Jars
Chives are among the most fragile and easily perishable herbs you can find at a grocery store. Much like your stash, improper protection against visible light ,as seen in the amber and clear glass above,will lead to a fast decomposition8 and degradation of the potency of your nugs.
The instant herb is exposed to unfiltered light, the decaying process begins. The potency and quality of your herb is degrading as you read this if you don't already use Herb Preserve jars.This is supported by extensive biophotonic research, which is the study of life and light. Herb can become dry and impotent in a matter of hours.
Herb Preserve stash jars can actually stop the decaying process while maintaining the freshness of your herb. What sets Herb Preserve biophotonic glass apart from all the other jars used in smoking history is that it blocks out all harmful visible light rays while selectively permitting infrared and UV-A rays. These rays are necessary to protect organic matter from the aging processes, which explains why the tomato and chives were still as fresh as the day they were put in the container in the lab tests. Furthermore, the screw top seal is completely airtight, and the thick glass is smell-proof.
Your herb is totally protected, preserved much like ancient Egyptians- who invented deep violet glass thousands of years ago- preserved precious oils and herbs for centuries in tombs. The integrity of your herb is guaranteed to be protected for over 6 months when you use our jars! That’s what makes Herb Preserve stash jars the world’s best.
