Cheap Cannabis Humidor on Amazon: Buying Guide

Advice first

Skip wood humidors made for cigars. Cigar humidors hold 70% relative humidity. Cannabis needs 58% to 62%. High humidity grows mold. Low humidity makes flower dry and harsh. A cheap Amazon humidor that works is an airtight container with a two-way humidity pack and a calibrated hygrometer.

Buy a glass jar with a gasket and latch. Amber glass blocks UV light. UV light degrades THC. A 1-quart jar holds about 1 ounce of flower. Add a Boveda 58% or 62% pack. Size the pack for the jar volume. A size 8 pack works for up to 1 ounce.

Check the hygrometer before you trust it. Cheap analog hygrometers on Amazon can be off by 10% RH. Buy a digital hygrometer. Calibrate it with a salt test. A salt test uses table salt and water in a sealed bag. It should read 75% RH after 24 hours.

Parameters to check

• Material: glass, stainless steel, or food-grade plastic. Avoid untreated wood. Wood absorbs terpenes.
• Seal: silicone gasket or rubber gasket. A latch or clamp. No screw-top jars if you open them often.
• Humidity control: two-way packs. Boveda or Integra Boost. Do not use a sponge or bead system.
• Hygrometer: digital. Accuracy ±2% RH. Analog is not reliable.
• Capacity: 1 ounce needs 1 quart. 2 ounces needs 2 quarts.
• Light: opaque or amber. Clear glass lets light in.
• Price: $15 to $40. Above $40 you pay for a brand name.

Pitfalls

• Wood humidors with Spanish cedar. Cedar oil can change the smell of cannabis.
• Humidors that ship with 69% or 72% packs. Those packs are for cigars. They push mold growth.
• Uncalibrated hygrometers. You will chase the wrong number.
• Cheap plastic that smells like chemicals. That smell transfers to flower.
• Small jars that hold 1/8 ounce. You will buy again.
• No UV protection. A clear jar on a shelf loses THC in weeks.

One last check: read the reviews for mold reports. Mold is the main failure. If reviews mention mold, skip that humidor.
