An ounce of flower is roughly 28 grams — weeks to months of supply for most people. That's the problem: by the time you reach the bottom of the bag, the flower has been losing moisture, terpenes, and potency the entire time. The last bowl never tastes like the first. Fixing it costs a few dollars and five minutes. Here's exactly how to store an ounce so the last gram smokes like the first.
Why the dispensary bag fails
The mylar zip bag or pop-top your ounce came in is built for transport, not storage. It's a passive barrier: it doesn't add humidity, doesn't block all light, and every reseal traps a little more air. Within 2–4 weeks the flower dries past the smooth zone, terpenes flatten, and the grind turns to dust. More on why passive bags fall short: trapping moisture vs managing it.
The four things an ounce needs
Airtight container. A quart (32 oz) mason jar holds about an ounce comfortably with low headspace. Glass is inert and won't off-gas. 62% RH, 2-way controlled. One Humidi-Cure® 62% pack per quart jar holds the flower in the smooth band and pulls it back from dryness automatically. Darkness. Light — UV especially — degrades THC faster than air or moderate heat; an opaque jar or a cupboard solves it. Stable, cool temperature. 60–70°F. Skip the fridge and freezer (here's why).
Three storage tiers for an ounce
| Tier | Setup | Best for |
|---|---|---|
| Good | Quart mason jar + 62% RH pack, in a cupboard | Most personal stashes |
| Better | Opaque/UV jar + 62% pack + RH indicator card | Bright rooms, longer holds |
| Best | ruksak™ ½ lb pouch — opaque, airtight, child-resistant, built-in 62% RH | Multiple ounces, homes with kids |
Don't subdivide more than you need
Every jar you open exposes flower to fresh air and light. If you've got an ounce, keep the bulk sealed in one well-controlled container and decant a few days' worth into a small jar for daily access. The main stash stays untouched at 62% RH; the working jar takes the wear. This single habit extends freshness more than any gadget.
Keep the last gram as good as the first
Drop a Humidi-Cure® 62% pack in your jar, or step up to a ruksak™ ½ lb pouch — opaque, airtight, child-resistant, 62% RH built in.

How long does an ounce stay fresh?
In a zip bag, 2–4 weeks before noticeable decline. In an airtight jar at 62% RH, dark and cool, 6–12 months.
How many 62% packs for an ounce?
One standard pack per quart jar (about an ounce). See choosing your RH for 58% vs 62% vs 65%.
Is a mason jar or a bag better for an ounce?
A mason jar with a 62% pack beats a passive bag. A purpose-built 2-way pouch beats both on light protection and child resistance — compare in ruksak vs mason jar vs mylar.
