Frequently Asked Questions

   Here’s why it’s the sweet spot:
Preserves Cannabinoids and Terpenes

• Cannabis contains volatile compounds like THC, CBD, and aromatic terpenes.
• At 62% RH, the flower retains maximum flavor and aroma without becoming too dry (which can cause these compounds to degrade or evaporate).

Maintains Ideal Texture

• Keeps the buds soft, sticky, and pliable, not brittle or crunchy.
• Prevents over-drying, which causes trichomes to break off and reduces the quality.

Prevents Mold Growth

• Mold and mildew thrive above 65% RH, especially near 70%.
• 62% strikes a balance: it’s moist enough to prevent dryness but low enough to stay below the danger zone for mold.

Improves Smoke Quality

• Properly cured cannabis at 62% RH results in a smoother, less harsh smoke.
• Over-dried weed can burn too hot and fast; too moist can be hard to light or taste musty.

Backed by Industry Standards

• Storage companies like Boveda and Integra Boost have studied this and developed humidity packs specifically targeting 62%.
• Growers and dispensaries often use this RH to extend shelf life and ensure product consistency.

 Canna Keepers jars combine Amish craftsmanship with a built‑in digital hydrometer. This means you can always see the exact humidity inside the jar — no guessing, just perfect storage conditions for cannabis, herbs, coffee, and more. 

 The hydrometer constantly measures the humidity inside the jar and displays it digitally. This lets you maintain the ideal storage level (around 62% for cannabis) by adding or removing humidity packs as needed. 

 Canna Keepers jars come in multiple sizes — from 8 oz personal jars to 1‑gallon bulk storage jars. Whether you need a single jar or a whole set, we’ve got you covered. .

Yes! We offer custom branding options for dispensaries, growers, and businesses. Add your logo, strain name, or special design to make your jars stand out. 

 Store your product in a Canna Keeper jar with the lid tightly closed. We recommend using a 62% humidity pack — the hydrometer will tell you when it’s time to replace it. 

Our jars are sourced directly from Amish and Mennonite craftspeople who’ve been perfecting their craft for generations. Each one is built with care, then fitted with our digital hydrometer system.
