Reliable 2-Way Humidity Control

Made from a non-toxic salt-and-water solution, completely food-safe and worry-free.
Convenient & Mess-Free
Each pack comes individually wrapped for maximum freshness. Remove the outer wrapper and place it inside your airtight container—the pack does the rest. For best results, replace every 3 months. (Tip: Do not mix different %RH levels in the same container.)
Versatile Protection
Perfect for herbs, coffee, tea, cigars, and more. Also trusted for protecting guitars, wood instruments, camera lenses, antiques, and rare books from the damaging effects of humidity swings.

Why Pay Attention to Trichomes?
- Clear Trichomes: The plant is still immature and hasn’t reached its full potential or size.
- Cloudy White Trichomes: The plant has reached its peak vitality and is at its most potent.
- Amber Trichomes: As the plant continues to mature, the trichomes turn amber (yellow).
- Spider Farmer Trichome Magnifier: Many growers already have smartphones with advanced cameras. With good lighting and a steady hand, you can easily capture clear, high-quality trichome photos, allowing you to track the plant’s progress and revisit them anytime.
- Handheld Magnifiers: These don’t provide enough magnification for a clear view.
- Jeweler’s Magnifiers: Affordable, but they have a small viewing window.
