NoBurp Bags & Lidz — Passive Cannabis Curing & Storage

EZ Trim NoBurp Bags & Lidz are passive cannabis curing and storage systems designed to reduce or eliminate the repetitive manual burping traditionally required when curing flower in sealed containers.

At the center of the NoBurp system is EZ Trim's patent-pending passive one-way valve technology. As cannabis cures inside a sealed container, moisture vapor, CO₂, ethylene, and other gases can accumulate. The NoBurp valve provides a passive outward path for these gases while restricting outside air from flowing back through the valve.

Instead of repeatedly opening a jar or bag on a schedule to exchange air, NoBurp allows the curing environment to vent passively while the container remains sealed.

NoBurp Bags

NoBurp Bags combine the passive one-way valve with a 130-micron, UV-protected, food-grade Mylar bag and heavy-duty resealable zip closure.

The bags are designed to provide a controlled environment for cannabis curing and storage while helping protect flower from outside air, light, odor transfer, and unnecessary handling.

For proper operation, fill the bag approximately 75–80%, leaving 20–25% headspace. This gives the flower and internal environment room to equalize and provides space for moisture vapor and gases released during curing to reach the one-way valve.

NoBurp Bags range from small personal and retail sizes through ½-pound, 1-pound, 2-pound, 5-pound, and 27-gallon commercial tote liners, allowing the same passive-curing concept to be used from small quantities through commercial harvest volumes.

NoBurp Bags ½ pound and larger include an integrated digital hygrometer, allowing RH to be monitored without opening the bag.

NoBurp Lidz

NoBurp Lidz bring the same passive one-way valve technology to traditional mason-jar curing.

Available for Regular Mouth and Wide Mouth mason jars, NoBurp Lidz replace the standard jar lid with a lid containing the NoBurp valve. This provides a passive outward vent path for moisture vapor and gases while restricting reverse airflow through the valve.

NoBurp Lidz are designed for growers who prefer curing and storing flower in glass but want to reduce the repetitive opening associated with traditional jar burping.

Mason jars are not included.

Proper Drying Comes First

NoBurp is a curing and storage system—not a replacement for properly drying cannabis before curing.

EZ Trim recommends beginning the curing process at approximately:

Flower Moisture Content: 10–12%

Water Activity (aW): 0.55–0.65

Target RH: 58–62%

Starting with properly dried and equalized flower is critical. Flower that is excessively wet should continue drying or Equalizing Dryness before being sealed for curing.

Why NoBurp?

Traditional jar curing requires the grower to repeatedly open containers to release accumulated moisture and gases.

NoBurp is designed to make this process more passive. Once properly prepared flower is loaded and the container is sealed, the one-way valve provides an outward vent path without requiring routine scheduled burping.

This can help reduce labor, repetitive handling, and the number of times flower must be exposed to the surrounding environment during curing.

NoBurp does not eliminate the need to monitor flower condition. Starting moisture, water activity, RH, temperature, flower density, cultivar, and other factors can all affect curing.

PRODUCT MANUAL

How NoBurp Works

NoBurp Bags & Lidz use EZ Trim's passive one-way valve technology to simplify cannabis curing without requiring routine scheduled manual burping.

During curing, cannabis can release moisture vapor, CO₂, ethylene, and other gases into the sealed container. The NoBurp valve provides an outward path for these gases while restricting outside air from flowing back through the valve.

NoBurp should be used with properly dried flower. It is designed for curing and storage and is not intended to replace the initial drying process.

Before Curing

1. Properly Dry and Equalize the Flower

Before placing cannabis into a NoBurp Bag or NoBurp Lidz-equipped jar, target approximately:

Flower Moisture Content: 10–12%

When water-activity testing is available:

Water Activity (aW): 0.55–0.65

Flower should also be reasonably equalized in dryness before curing. If some buds remain substantially wetter than others, continue drying or Equalizing Dryness before sealing the flower in the curing container.

2. Separate Strains When Possible

When practical, cure one strain per bag or container.

Different cultivars, flower structures, and bud densities can retain and release moisture differently. Separating them makes it easier to maintain and evaluate a consistent curing environment.

Filling NoBurp Bags

1. Fill Approximately 75–80%

Fill the NoBurp Bag approximately 75–80%, leaving about 20–25% headspace.

Do not tightly pack or compress the flower.

The remaining space allows the flower and internal environment to equalize and gives moisture vapor and gases released during curing room to reach the valve.

2. Gently Remove Excess Air

Before completely sealing the bag, gently press out excess air.

Do not compress the flower.

3. Completely Seal the Bag

Close the heavy-duty resealable zipper completely across the top.

Check the entire closure to ensure that it is properly sealed.

NoBurp Bags also incorporate a heat-sealable opening when a more permanent package seal is desired.

Once sealed, the NoBurp valve can passively vent moisture vapor and gases from inside the bag without requiring routine scheduled burping.

Using NoBurp Lidz

Place properly dried and equalized flower into a compatible mason jar.

Leave adequate headspace rather than tightly packing the jar.

Install the appropriate Regular Mouth or Wide Mouth NoBurp Lidz and ensure the lid is properly seated and sealed.

The NoBurp valve will then provide the same passive outward venting concept used in NoBurp Bags.

Monitoring the Cure

For ½-pound and larger NoBurp Bags, use the integrated digital hygrometer to monitor the internal relative humidity.

Target RH: approximately 58–62%.

Check the flower periodically, particularly during the beginning of a new cure.

If RH remains substantially above the desired range, the flower may have entered the bag too wet. Open the bag if necessary and allow the flower to continue drying or equalizing before resealing.

If RH is substantially below the desired range, the flower may have been dried beyond the preferred starting condition.

The NoBurp valve manages outward venting; it cannot correct improperly dried flower.

Storage During Curing

Store sealed NoBurp Bags or Lidz-equipped jars in a cool, dark environment away from excessive heat and direct sunlight.

Avoid unnecessary opening and handling during the curing period.

The passive valve is designed to reduce the need for routine scheduled burping, but flower condition should still be monitored.

Curing Time

A typical curing period may be approximately 2–4 weeks, but curing time varies.

Cultivar, bud density, starting moisture, water activity, temperature, RH, and other conditions can affect how the flower cures.

Use flower condition and available measurements rather than time alone to determine when the desired cure has been achieved.

Long-Term Storage

Once the desired cure has been reached, NoBurp Bags can continue to be used for flower storage.

Keep the bag properly sealed and stored away from excessive heat and light. Minimize unnecessary opening and handling to help maintain the storage environment.

Important

NoBurp is designed to simplify cannabis curing—not compensate for improper drying.

For best results:

Dry properly → Equalize Dryness → Verify moisture condition → Load NoBurp → Seal → Monitor → Cure → Store

Frequently asked questions

EZ Trim NoBurp Bags & Lidz are cannabis curing and storage systems that use a passive one-way valve to reduce or eliminate the need for routine manual burping.

During curing, the valve allows moisture vapor, CO₂, ethylene, and other gases generated inside the container to vent outward while restricting outside air from flowing back through the valve.

NoBurp Bags use the valve in a resealable Mylar bag, while NoBurp Lidz bring the same passive-curing concept to regular-mouth and wide-mouth mason jars.

Under normal curing conditions, routine scheduled burping should not be necessary.

The NoBurp valve provides passive outward venting while the bag or jar remains sealed. However, NoBurp does not eliminate the need to monitor the flower.

If the flower enters the container too wet or the internal RH remains above the desired range, open the container and allow the flower to dry further before resealing it.

NoBurp is designed for curing properly dried cannabis, not as a replacement for the initial drying process.

EZ Trim recommends starting at approximately 10–12% flower moisture content. When water-activity testing is available, the target starting range is approximately 0.55–0.65 aW.

Starting with properly dried and equalized flower is important for a successful cure.

The target curing range is approximately 58–62% relative humidity.

NoBurp Bags ½ pound and larger include a built-in digital thermometer and hygrometer so temperature and RH can be checked without opening the bag.

If RH remains too high, the flower may have been sealed with too much moisture. Open the bag and, if necessary, allow the flower to dry further before resealing it.

Fill the bag to approximately 75–80% of its capacity, leaving about 20–25% headspace.

Before sealing, gently press out excess air without compressing the flower. Then completely close the heavy-duty resealable zipper.

Leaving adequate headspace gives the flower and internal environment room to equalize during curing.

The NoBurp instructions recommend a typical curing period of approximately 2–4 weeks, although actual curing time can vary based on the flower, starting moisture, storage environment, and desired finished characteristics.

Rather than relying only on time, continue monitoring the condition of the flower throughout the curing process.

Both use the NoBurp passive one-way valve, but they provide different container options.

NoBurp Bags use food-grade, UV-protected Mylar with a heavy-duty resealable zipper. Bags ½ pound and larger also include a built-in digital thermometer and hygrometer.

NoBurp Lidz are designed for growers who prefer curing in glass mason jars. They are available for regular-mouth and wide-mouth mason jars and replace the standard lid with a NoBurp valve-equipped lid.

Mason jars are not included.

Yes, NoBurp Bags can be reused as long as the bag, zipper, seams, valve, viewing window, and hygrometer where equipped remain in suitable condition.

After use, empty and clean the bag appropriately and allow it to dry completely before reuse.

Do not reuse a bag that is punctured or damaged, cannot be properly sealed, or has a valve or closure that is no longer functioning correctly.
