First pick: CVault with a Boveda pack

The CVault is a 304 stainless steel container with a latch and a silicone gasket. The lid holds a Boveda pack against the top. Sizes run from 1/8 oz to 2 lb. Steel blocks light. The gasket holds a seal under pressure. Boveda packs come in 58% and 62% relative humidity versions and move moisture both ways. A 62% pack suits flower you plan to smoke. A 58% pack suits material you plan to vape or grind soon. Small CVault units start near $30. Large units run past $90. This is the pick for storage of six months or more.

Option 2: Cannador

The Cannador is a wood box with dividers and a slot for a humidity pack. It looks like a cigar humidor. Wood absorbs and releases moisture, so the internal RH drifts more than steel or glass. The seal is not airtight. Price runs $150 and up. Buy it for display, not for a year of storage.

Option 3: Mason jar plus Boveda

A Ball or Kerr quart jar costs $3 to $5. Add one 8 g Boveda 62% pack. The lid is airtight. Glass blocks visible light but not UV. Keep the jar in a closet or a drawer. This setup costs under $10 and holds about an ounce. It is the cheapest option that works.

Option 4: Infinity Jar

Option 5: Tightvac or Herb Guard

Both are opaque plastic containers with a press and seal lid. They block light and cost $20 to $30. Plastic can pick up odor over time and holds static, which pulls trichomes. Use them for transport more than for long term storage.

What to compare

Numbers that matter

Target 58% to 62% RH. Target 60°F to 70°F. Keep the container out of sunlight. Oxygen drives terpene loss, so open the lid as little as possible. Burp new flower once a week for the first two weeks, then seal it. Do not use a cigar humidor at 70% RH. Do not store flower in a fridge or freezer. Condensation and ice crystals damage trichomes.

Avoid

Skip humidors that use propylene glycol solution. Skip clear plastic bags for storage past a few days. Skip any container that lets in light or air.
