Quality of marijuana: these the key factors to consider

Before knowing the right conservation methods for quite long periods, it is good to analyze which are the conditions that cause the degradation of our legal hemp tops.

To ensure that CBD cannabis preserves its quality, in fact, it is essential to preserve it with care and in an adequate manner.

But how?

Among the variables that affect legal hemp deterioration, the first to consider is temperature – consider that most bacteria form between 25 and 30 °C. Among these, there is the mould that makes it unusable (but we will see that in a moment).

Also, too high temperatures damage the compounds contained in CBD weed, namely cannabinoids and terpenes, significantly lowering their quality and decreasing their power.

Moisture is another factor to consider as excessively low levels lead to excessive drying of the hemp, spoiling the aromas, while excessively high levels favor the spread of mold and fungus.

In fact, the ideal humidity levels fluctuate between 59% and 63%.

Finally, light and air circulation can also play a fundamental role in the conservation.

If kept in the right conditions, therefore, it is possible to preserve the quality of your own legal weed for periods ranging from six months to a year.

Marijuana storage: the three methods

Before going on, it is important to mention that weed can be store differently according to the amount of time.

It means that you need to know different things if you decide to store marijuana for one week or one month. So let’s have a look at the timing recommended for cannabis storage:

Short-term storage< one week
Medium-term storage30 days
Long-term storage> 30 days

Okay, now let’s dig deeper.

Short-term storage

Short-term storage means less than one week. However, when you intend to consume weed within a few days, it is advisable to store it in a small container, preferably made of silicone, so that not too much air can pass through it, as oxygen can damage the quality of hashish.

Medium-term storage

When you intend to store your weed for more extended periods (around thirty days), it is best to use an airtight container. Once divided into pieces, these should be wrapped in greaseproof paper and then put in a plastic bag. As we have said on several occasions, it will lose its properties if it becomes damp.

Therefore, weed should be in an optimal state, neither too wet nor too dry.

Long-term storage

If weed is stored for more than a month, it should be placed in a vacuum container to prevent condensation and slow down aging, an inevitable process that alters its quality to some extent; aging reduces the level of THC, which is converted into another cannabinoid, CBN. The taste is also changed, becoming more bitter.

In any case, whether it is stored for a short, medium or long time, it is necessary to store the hashish in a cool place with a temperature below 25.5° C to prevent mould from forming. In addition, the storage environment should always remain clean, dry (to prevent the hashish from absorbing too much moisture), and dark.

But that’s not all.

Each jar should be filled to ¾ full so that there is enough space and stored in airtight glass or ceramic containers. Plastic is not recommended as it can accelerate the ageing process of the substance.

Having said that, the question is basically automatic: which are the best containers to use?

How to store marijuana: the step-by-step guide

As we have just said in the previous paragraph, the first rule to be respected to best preserve the CBD flowers is to avoid plastic!

The plastic bags allow the passage of air and light, creating humidity inside. Furthermore, plastic releases chemical molecules that should be avoided.

The plastic bags, therefore, are used only for transporting the tops.

That said, the best containers for storing marijuana are the glass jars with hermetic closure to be kept in cool and dark places.

In addition, it is necessary to open the can only when necessary, so as to avoid unnecessary and excessive temperature changes that would damage the quality of the hemp compounds, compromising their aroma and smell.

The glass jars are also ideal because they make it easier to keep the buds intact, so as not to damage the crystallized trichomes contained in the cannabis CBD, avoiding losing important quantities of resin.

In reality, it is also possible to find humidifying bags on the market that are useful for maintaining the humidity percentage stable, so as to be certain of having a quality product that lasts over time.

After having warned of the use of plastic bags, however, another myth must be dispelled: you don’t have to keep CBD buds in the freezer!

Temperature changes can damage the freshness of the product and promote the proliferation of bacteria.

The frozen peaks then transform the trichomes into small pieces of ice which, of course, will break, greatly reducing the power of the hemp itself.

How to tell if the hemp is still in good condition

Mould formation is far from pleasant, both in cannabis foods and hashish, but unfortunately, it is widespread and particularly troublesome. If the product is not stored correctly, mould may appear within a few weeks! So, here are some tips to prevent its formation:

  • Ensure proper air circulation to prevent moisture accumulation
  • Avoid over-watering the seedling
  • Dry and season the product correctly: the room where it is stored should ideally have a humidity of 35% and a temperature of 12° C
  • Avoid airtight containers
  • Avoid hot places
  • Minimise the impact of environmental factors

When weed becomes mouldy, it is best to get rid of it immediately. However, some recommend that you do not throw it in the rubbish bin but instead heat it at a temperature of 95° C for 15 minutes because the mould will not survive temperatures above 60° C.

However, the best choice is not to take unnecessary risks and avoid using weed if you notice any signs of inadequate storage.

Furthermore, before using the buds set aside for a certain period of time, you always must make sure they are still in good condition.

Cannabis CBD, in fact, like other living beings, is subject to deterioration caused by the passage of time and therefore, it would be better to check the condition of the buds so as to avoid CBD weed which is by now stale, dry and without taste.

The first suggestion simply concerns the observation of the peaks that, to be still of quality, must be covered by a layer of small crystals, as the trichomes, producers of cannabinoids and terpenes.

In fact, the therapeutic properties of legal marijuana are essential to preserve the power, but also its aroma.

The more trichomes are observed, the better the quality is!

A further check is given by the sense of smell. Terpenes are the first compounds exposed to degradation during a long storage period, and when their concentrations decrease, the aroma of our legal CBD cannabis loses its intensity.

The state of the CBD bud can also be assessed through touch: quality buds must not appear either too moist or too dry, nor should they crumble at the slightest pressure.

If they appear wet or anyway soaked, they must be left in the open air, while if they are too dry they are fragile and then can be easily pulverized.

To conclude, a more than legitimate question concerns a possible expiry date of legal cannabis.

Let’s keep it clear: the answer is no. That means, this is not a food that if consumed after several months can make us feel bad, but using contaminated cannabis is not recommended.

All of this simply means adopting suitable methods for its adequate conservation to avoid altering the compounds, aromas and flavors of our CBD flower.

In conclusion, preserving the quality of marijuana, particularly CBD cannabis, requires careful attention to key factors such as temperature, moisture, light, and air circulation. These factors can significantly affect the degradation of cannabinoids and terpenes, leading to a decrease in quality and potency.

To ensure proper storage, it is recommended to use appropriate containers such as glass jars with airtight closures, avoiding plastic bags that allow the passage of air and light. Maintaining optimal humidity levels between 59% and 63% is crucial for preventing excessive drying or the growth of mold and fungus. Different storage methods are suggested based on the duration: short-term storage (< one week), medium-term storage (around thirty days), and long-term storage (> 30 days).

It is important to avoid temperature fluctuations, excessive moisture, and airtight containers. Proper storage can help preserve the quality of marijuana for extended periods, ranging from six months to a year. Regular inspections of the buds are recommended to ensure they are still in good condition, characterized by the presence of trichomes, intact aroma, and appropriate moisture levels. By following these guidelines, users can enjoy the therapeutic properties and aromatic experience of high-quality marijuana.
