How Long Can You Store Weed Before It Gets Moldy?

Mold spores are all around us and can be especially damaging to human health if consumed. This is why when it comes to cannabis it’s important to protect your consumables, because you don’t want to be wasting your products, harming your body and losing money.

The world of marijuana storage has come a long ways since the olden days which included plastic baggies and maybe an empty prescription medication container. Although these methods can sometimes help retain some freshness and protect the herb for a little while, they aren’t doing much to prevent any possible mold from developing.

Now in 2018, cannabis storage technology has immensely improved, making it that much simpler to not need to worry about your weed anymore, but even with advanced technologies, everything has its limit of preservation.

How Long Does Weed Stay Fresh?

When it comes to marijuana, freshness and free from mold should not be synonymous. Your cannabis will stay fresh for a certain period of time, and sometimes if it is no longer fresh, it does not mean it’s moldy. Freshness simply implies the herb is not so dry that it becomes crusty, and that its pungence, aroma and usual coloration still remains. It is said that with proper storage practices, your good green stuff can be kept for up to 6 months, but this doesn’t necessarily mean it’s off the hook from getting moldy during the 6 month period. If your bud drying up is more so what you’re concerned about, then be sure to keep it in an airtight container that is not too big for the amount of herb, as well as keeping it away from too much light or heat exposure.

How Does Weed Get Moldy?

There are two main kinds of mold that can affect cannabis, one of them is generated during the cultivation process before the ganja has been harvested, while the other only occurs after curing has already happened.

Botrytis cinerea, also known as the infamous bud rot, is the type of molding process present during the cultivation of the plant. It begins to grow all the way down at the stem of the buds and slowly makes its way into them, sometimes completely inhabiting the flowers from the inside out. It kills useable buds, turning them into a squishy and moist mess, and it can actually ruin entire colas easily, making them non consumable. This molding process is usually caused because of humidity and a lack of airflow, which causes growth encouraging moisture to get trapped inside the dense colas and buds, leading to the bud rot. If you’re not a cannabis cultivator, you won’t need to worry about this type of rot, because if you’re buying your bud from a reputable dispensary, they won’t be selling marijuana that has bud rot in it. Most of all, you’ll be able to see a white film layer that starts at the stem and goes upwards, so there will be a visible presence if this is the situation.

The other type of possible mold that affects cannabis is known as aspergillus. It is an airborne mold usually, and can grow on not only marijuana, but fresh produce and other foods too. It is quite difficult to notice at first with the naked eye, and especially with a very frosty cannabis bud, it could be mistaken for the frosty crystals. There are a few hundred different types of aspergillus mold, and the spores are just about everywhere, indoors and outdoors. What causes the mold to grow, however, depends heavily upon conditions, and therefore the environment must be one which supports the thriving. Environments that are humid, or with a source of water present, in addition to lacking a source of air circulation, make the perfect space for this mold to flourish.

How to Tell If Your Weed Has Mold?

Mold can thrive in bud that has a 15% humidity content or higher. Any less than this and it’s unlikely that mold spores will be capable of surviving, in addition to thriving. At first it is a bit challenging to see the spores growing and developing, but once the amount has gotten to a mass level, it becomes visible to the naked eye. This can be problematic, because you could have been smoking this contaminated weed and not even have known it. Usually, a good way to judge is by using your other senses.

If you open up your stash and it has an overly sweet, musty or stale smell, then there’s a fair chance that mold could be growing. Furthermore, touching the bud and giving it a bit of a pinch can work wonders, because if the nugget feels damp or wet instead of simply dry and sticky, it could mean there is some trapped-in moisture. Most of all, if you take a hit of your cannabis and suddenly beginning having an allergic reaction or coughing profusely in strange ways that aren’t normal or typical, don’t just assume your weed is strong- consider the fact that maybe it has some mold spores in there. If you have a few of these signs combined, then the chances of moldy bud is even more likely.

What to Do If Your Weed Has Mold?

Unfortunately, the only real solution if your already cured bud starts growing mold, is to throw it away. Of course wasting this gift from Mother Nature herself is such a shame, but consuming and especially smoking aspergillus is extremely harmful to your health and is not recommended. In this circumstance, it is better to waste the money than allow something to harm your body. Money comes and goes, but your health is irreplaceable.

The best way to assure that mold is not present, is to only buy laboratory tested marijuana from a reputable dispensary. Actual scientists and professionals are checking this cannabis to make sure it’s safe for your consumption, guaranteeing that you won’t get sick.

How Long Does It Take For Weed to Become Moldy?:

There’s no definite answer to this question, for not all cannabis is guaranteed to get moldy, especially if extra precautions are taken and quality assurance marijuana is purchased instead of just something random with an unknown origin. In humid conditions with little to no airflow it could take a matter of days for the spores to thrive and flourish, so it isn’t as much about the length of alloted time for mold to be present, rather the quality of cannabis and the facility in which is was cultivated.

The Best Ways to Store Your Cannabis:

Contrary to popular belief, keeping your ganja in an air tight container with plenty of humidity trapped inside or just baggies that get packed and never opened is not a smart move. Trapping air means not enough airflow, which creates the perfect incubator for mold to start its growing process if the spores are already stuck in that space. Additionally, some growers add in orange peels or fruit peels to keep the cannabis fresh, but all this does is blend the buds with any mold spores that may have been located on the fruits to begin with. The best way to get rid of excess humidity and prevent mold, is by storing your tested cannabis buds in an airtight container that also contains some type of humidity pack, because these little devices absorb excess moisture. Most of all, pick buds that don’t smell off, don’t feel damp to your fingertips and that appear fresh with no visual signs of mold. Purchase your weed for a place you know you can trust and go over some of the obvious signs before agreeing to buy if it isn’t from a lab tested dispensary.
