Grow Tools Mylar Bag - Light-Proof, Odour-Proof Storage for Dried Flower
Best for: growers who need to store or transport dried, cured flower without losing freshness, aroma or potency.
Our thoughts
A jar is fine for a small stash, but once you're storing or moving anything in bulk, a proper mylar bag does a better job of keeping light, air and smell out. Cheap, simple, and it actually protects what you've spent months growing.
The Grow Tools Mylar Bag is a foil-lined bag designed for long-term storage of dried herbs and cured flower. The metallised lining blocks out light and UV, which degrade cannabinoids and terpenes over time, while the heat-sealable closure locks out moisture and air far more effectively than a standard zip-lock bag once properly sealed.
It's available in a few sizes to suit anything from a small personal stash to bulk curing or transport, and works equally well for short-term storage using the resealable opening or long-term storage once heat-sealed shut.
How it compares
Mylar bags are a simple, well-understood storage format, and the differences between brands come down to thickness and seal quality.
- Grove Bags offer a similar smell-proof storage concept but use a different material designed to actively manage humidity rather than just block light and air.
- Standard resealable zip-lock mylar bags (widely sold for food storage) do a similar basic job but are rarely heat-sealable for true long-term storage.
- Glass jars are reusable and easy to check without opening, but don't pack down flat or protect against light as completely once opened repeatedly.
It's a cheap way to get genuinely long-term, light-proof storage rather than relying on a jar or sandwich bag.
Usage guidance
Get the seal right and it'll outperform most other storage you've got at home.
Filling
Make sure flower is fully cured and at the right moisture level before sealing, trapping excess moisture in a sealed bag risks mould.
Sealing
Push out excess air before sealing, then heat-seal with a household iron on a low setting or a hair straightener along the top edge for a proper long-term seal.
Storage conditions
Keep sealed bags somewhere cool, dark and dry, the bag blocks light but doesn't control temperature or humidity on its own.

Who this is for
- Growers storing or curing larger harvests than a jar can comfortably hold
- Anyone transporting dried flower who wants it sealed and protected
- Growers who want long-term storage that actually blocks light and air properly
Best suited to bulk or long-term storage rather than a single jar's worth for daily use.
Our take
It's a small cost for protecting a harvest that took months of work, light and air exposure are the main things that degrade cured flower in storage, and this blocks both properly once sealed.
Worth picking up if you're storing more than a jar's worth or need it to travel.
