Grove Bags TerpLoc is the best pick for curing cannabis if convenience decides the purchase: it needs no burping, holds humidity near 62% RH, and stores flat. Wide-mouth quart Mason jars stay the best value option for growers who do not mind opening lids daily. CVault and Infinity Jar fill the middle ground with steel or glass bodies and built-in humidity control.
What is the best jar for curing cannabis?
Grove Bags TerpLoc wins overall. The multilayer film releases oxygen and carbon dioxide while keeping moisture and terpenes inside, so a sealed bag does the work a burped jar does.
Cannabis Curing Jars Size Per Ounce: Jar Sizing Guide
Mason jars win on price and availability. A quart jar with a two-piece lid costs a few dollars, holds about an ounce of dried flower, and adds no plastic taste.
cannabis curing jars humidity level
1. Grove Bags TerpLoc: best overall
- Zero burping required after the first week
- Humidity stays in the 58% to 62% RH band
- Heat-sealable and reusable for multiple runs
- Sizes from 1 ounce to 1 pound
Convenience is the whole pitch. Seal the bag, store it in a dark drawer at 60 to 70 F, and check it once a week.
where to buy large curing jars for cannabis
2. Ball wide-mouth Mason jars: best value
Quart size handles roughly one ounce of dried flower. Pint jars suit small harvests, half-gallon jars suit large ones.
The downside is labor. You must burp each jar for a few minutes daily through the first two weeks.
3. CVault with Boveda: best humidity control
A stainless steel body, a latching lid, and a slot that holds a Boveda pack against the lid. Light cannot reach the flower.
Cost runs higher than glass, and the opaque body hides how the cure looks.
4. Infinity Jar: best burp-free glass
Thick glass with an airtight silicone seal and a humidity pack holder. It gives glass purity without daily lid work.
It is heavier and pricier than Mason jars, and the seal needs replacement over time.
Has convenience become the deciding factor in cannabis curing?
Yes for most home growers. Ready-to-use packaging and two-way humidity packs removed the daily chore that used to define curing, and shoppers now pay a premium for that.
Convenience does not beat cost for everyone. Growers with large harvests still buy Mason jars by the case because glass is cheap, inert, and stackable.
The practical split: buy Grove Bags or Infinity Jar when time matters, Mason jars when budget matters, CVault when humidity precision matters.
How to choose a curing jar
- Match volume to harvest: about 1 ounce per quart jar.
- Pick a seal that holds 58% to 62% RH. Silicone gaskets and TerpLoc film both qualify.
- Block light. Amber glass, steel, or a dark cabinet all work.
- Decide on burping. If you will not open jars daily, choose a burp-free option.
FAQ
Do you still have to burp cannabis in a jar?
Yes with glass. Burp daily for the first 10 to 14 days, then weekly. TerpLoc bags and Infinity Jars with humidity packs skip most of that schedule.
What size jar cures one plant?
Plan on one quart jar per ounce of dried flower. A typical indoor plant yields 2 to 4 ounces, so 3 to 4 quart jars cover it.
How long does curing take?
Two to four weeks minimum, with flavor peaking around week four to eight. Cure longer for a smoother smoke.
Verdict
Grove Bags TerpLoc is the best jar for curing cannabis when convenience is the deciding factor. Mason jars remain the best value, CVault is best for humidity precision, and Infinity Jar is the best glass option that skips daily burping.
