burping weed

How long do you guys *Burp* your jars? no newbs please..


I understand the concept, and follow the rules.. But what are the best *burp* times?

I know a lot of ppl on here come to a crawling, slow and painful finish when it comes to harvesting, if at all. So please only experienced grower’s comments welcome Lol. not to be a dick, I just dont wanna hear what you “heard” works best..anyways:

off one plant I raked in over 234g of chronic. A lil over half P. I have (11) (12oz I think) Mason jars, filled w 20g ea..
and one other side jar. So the jars are filled I’d say abt 80% ea.

**SO I’d like the “perfect cure” Anyone have any suggestions on burping times? how long/how often..

And if u don’t know from experience, please go troll another thread HAHA jk

Ya mine hung for 7 days, then just jarred up yesterday.

So how long do u leave the jars open for? I was thinking abt 20 min, 2-3 times a day. Maybe 1-2 times a day? IDK lol

I do what this guy said:

]Burp the jars when you see moisture forming on the jar. If you can go buy a hygrometer that will help with drying your buds correctly. That way you can monitor the RH inside the jar, if it increases several % an hour, you want to burp them for an hour or two, this can be done with the lid off, or you can put it in a brown paper bag for a more even dry. A 3 week cure is good, month or more is optimal. Heres some more info to help with RH levels if you buy a hygrometer.

Cut the product, trim it per your preference, but don’t dry it until the stems snap. Take it down while the stems still have some flex, but the product feel dry on the outside. This is a perfect opportunity to drop the dry-feeling flowers onto a screen and collect prime-quality kief that would otherwise get lost in the jar.

Jar the product, along with a Caliber III hygrometer. One can be had on Ebay for

$20. Having tested a number of hygrometers – digital and analog – this model in particular produced consistent, accurate results. Then, watch the readings:

+70% RH – too wet, needs to sit outside the jar to dry for 12-24 hours, depending.

65-70% RH – the product is almost in the cure zone, if you will. It can be slowly brought to optimum RH by opening the lid for 2-4 hours.

60-65% RH – the stems snap, the product feels a bit sticky, and it is curing.

55-60% RH – at this point it can be stored for an extended period (3 months or more) without worrying about mold. The product will continue to cure.

Below 55% RH – the RH is too low for the curing process to take place. The product starts to feel brittle. Once you’ve hit this point, nothing will make it better. Adding moisture won’t restart the curing process; it will just make the product wet. If you measure a RH below 55% don’t panic. Read below:

Obviously, the product need time to sweat in the jar. As such, accurate readings won’t be seen for

24 hours, assuming the flowers are in the optimal cure zone. If you’re curing the product for long-term storage, give the flowers 4-5 days for an accurate reading. If the product is sill very wet, a +70% RH reading will show within hours. If you see the RH rising

1% per hour, keep a close eye on the product, as it’s likely too moist.

I understand the concept, and follow the rules.. But what are the best *burp* times? I know a lot of ppl on here come to a crawling, slow and painful…

The Art of Curing Your Cannabis Crop

Takeaway: You’ve worked hard to grow a potent and flavorful crop, but now what? Follow Cory Hughes’s advice to keep your cannabis fresh and mold-free during storage, and don’t forget to burp your nugs.

Your months of hard work in the garden have paid off and your crop is almost ready to go. Your plants are harvested and the nugs are trimmed and dried. The next steps you take will determine not only the potency of your cannabis but its essence, flavor and aroma.

The curing process is essential in putting the finishing touches on the beautiful green buds you’ve worked so hard to grow. Proper curing and storage of your finely crafted buds will make or break your finished product.

The first step in properly curing your cannabis is making sure your buds are properly dried. You want your buds in an optimal moisture zone. When a plant is harvested, it will lose 80 per cent of its moisture before it is consumable.

You want to start the curing process before your buds get to that point. Ideally you want your buds at around 30 to 35 per cent moisture, a fraction of their original wet weight. Any more moisture than that and you risk the development of mildew and mold once sealed in an airtight environment. If you dried your flowers too long or at too high of a temperature, you may need to rehydrate them.

Just make sure that your weed is in that Goldilocks zone before you begin your cure. If you are not sure, you can test your bud by simply bending a stem. If the stem breaks or starts to break, then it is sufficiently dry. If it continues to bend, it should probably dry for another day or more.

One of the chemical secrets to curing is cannabigerol, or CBG. Cannabigerol is the chemical precursor found in cannabis that metabolizes into THC. It is believed that CBG has profound medical impact on its own.

CBG reduces pressure in cell walls and is a big part of cannabis treatment for glaucoma. It is considered to be the primary cannabinoid, as it is broken down inside the plant in order to create THCA, CBDA and CBCA.

We are all familiar with THC and CBD but CBC, or cannabichromenic acid, is by far the lesser known of the cannabinoids. Due to its involvement in the creation of other cannabinoids, CBG is usually found in concentrations of less than one per cent in finished products.

After the plant is harvested, the metabolic process that creates THC from CBG continues. This results in THC levels rising long after the buds have been collected.

Some people choose to begin the curing process in paper bags to make sure they are adequately dry. I haven’t found this to be a necessity, so I go straight for airtight glass jars.

A mason jar or a jar with a flip-tight lid are optimal as they perfectly seal and keep air out. You will want to place as much marijuana in your jar as possible in order to force out as much of the remaining air as you can.

Always date your jars so as to not confuse them with other batches you may have already started!

Creating Potency and Flavor of Cannabis Through Proper Curing Techniques

The primary functions of curing are potency and flavor. As the chemical components of the plant matter break down over time, it shifts the taste from an overly earthy and green flavor to flavors that are more palatable and that we can more readily associate with particular strains.

This process is conducted by aerobic bacteria present in the plant at the time of harvest. The bacteria consume the chlorophyll in the cannabis making the taste and overall experience less harsh. Just like your grow, your curing buds thrive in a micro-environment dependent on specific conditions in order to nurture the process.

If your buds are overly moist when you start to cure, you run the risk of allowing mold to grow, which can lead to harmful bacteria destroying the fruits of your labor.

It is important to keep your cure in a dark room or storage area. Light will degrade THC and interfere with the metabolic process taking place in your jars. Maintenance of the micro-environment is vital to keep your good bacteria thriving and your bad bacteria at bay. Your temperatures should be slightly lower than your growroom at around 50-75˚F. Now that you have an idea of what conditions you need to cure your cannabis, you can begin without further delay.

Burp Your Nugs

The key to curing your cannabis is burping your jars. That means after allowing the metabolic process to work, periodically opening your jars to let out the built up carbon dioxide and moisture the buds have shed. Every grower has their own schedule of burping and they all vary greatly. For buds that are in the right humidity zone, you should burp them daily for approximately 30 minutes.

Everyone will have an opinion on the time, however, 30 minutes is sufficient to expel the gasses and allow the micro-environment to return to an acceptable relative humidity. Some choose to use an RH meter to determine the amount of time they burp their buds. You should keep the relative humidity above 55 per cent.

Below that threshold your buds don’t have the moisture required to allow the metabolic process to continue. If you burp your nugs and find you still have a relative humidity more than 70 per cent then they need to come out of the jar and be allowed to dry more thoroughly. How long you cure for is really up to you.

Most growers will tell you that with daily burping under right conditions, your buds should be delicious and potent in three weeks to a month. Others who have cured their cannabis for months or even years claim that their product only improved the longer it cures. If you have the patience to cure your weed for six months or more, you are a better person than I.

Stick With Glass Jars for Curing Cannabis

Now that you have properly cured some dynamite bud, it is time to prep it for storage. Storing your weed under proper conditions will preserve your THC content and allow for quality consumption at a later date. I think it goes without saying, but never use plastic bags for storage, or anything else.

Stick with your airtight glass jars. Some prefer dark-colored glass to prevent light from creeping in but if you are keeping your jars in a drawer or closet, clear jars are just fine. Glass doesn’t breathe like plastic. Avoid freezing your cannabis.

The freezing process turns the trichomes brittle. You can end up damaging your buds when there is really no need. Molds and mildews will spread at high temperatures, so never allow your stored weed to go above 77˚F. All in all, keep your airtight jars of cannabis in a cool and dark location that won’t be disturbed by your day-to-day routine.

For long-term storage, you still want to burp your jars once or twice a month just to let out the gasses your buds will continue to give off. The result will be cannabis that is as good, if not better than it was on the day it was stashed away.

You’ve worked hard to grow a potent and flavorful crop, but now what? Follow Cory Hughes’s advice to keep your cannabis fresh and mold-free during storage, and don’t forget to burp your nugs.
