Exposure to oxygen is a big factor when it comes to preserving your weed. Too much oxygen can degrade your weed and too little oxygen can alter humidity levels which can cause your weed to get mouldy. Always store your weed in a vacuum sealed bag or in an airtight container to preserve its potency.
Harmful UV Light can heat up your cannabis plant and degrade its valuable compounds like cannabinoids and terpenes. To avoid this, store your bud in an opaque glass jar in a dark and dry place away from sunlight. Humidity plays a very important in the preservation of your weed. Too much humidity can promote mould and taint your bud, while weed that is too dry will cause the terpenes and cannabinoids in it to degrade. Therefore it’s important to maintain proper humidity levels which can be managed with humidity control packets, a humidor, etc. High temperature can also cause buds to become too dry degrading the cannabinoids and terpenes. Mould and mildew thrive in temperatures between 78 to 86 degrees, therefore, the ideal storage for cannabis is below this threshold. Properly stored buds smoke or vaporize perfectly and retain the flavour and cannabinoid profile, but what happens when you don’t store buds the right way?
How does improper cannabis storage affect its quality? If you haven’t paid attention to the right methods for storing cannabis chances are that your bud will lose its potency over time. It simply means that its chemical structure has changed. Let’s see typically what happens when weed is not stored correctly. Marijuana has a number of chemical compounds present in it which are known as cannabinoids. For example, tetrahydrocannabinolic acid (THCA) is a cannabinoic acid present in freshly harvested cannabis flowers. However, THCA cannot get you high and must be converted into THC through a process known as decarboxylation. When fresh buds are cured, dried and then heated, the process of decarboxylation begins whereby cannabinoids are broken down into THC, CBD and CBN among others. When cannabis is exposed to excessive heat or oxygen on account of being stored improperly, the THC can get converted to a different cannabinoid called CBN. CBN is less psychoactive than THC meaning consumption will not get you very high. Instead, CBN plays an important role in regulating sleep so smoking bud which contains CBN will in all likelihood make you drowsy but don’t expect to get high. Dry weed makes for a very unpleasant smoking session. To preserve the integrity of weed one must control the humidity as weed needs to be stored at a relative humidity level between 59 to 63. Excessive heat can cause the terpenes and cannabinoids in weed to dry out resulting in a harsh smoke that will burn the throat when inhaled. Moisture is marijuana’s worst enemy and when weed is exposed to it, chances of mould developing are seriously high. Smoking mouldy weed is a big mistake as the mould in the weed can enter your lungs and cause serious infections from a basic cough, to fever and fatigue. Fortunately, it’s easy to identify if your weed has gotten mouldy. Just hold your bud in the light and carefully examine it. If you see white powdery flakes or whitish layers on the weed, it’s most likely been compromised with mould. Since weed does not expire quite like cheese or milk identifying if it has gone bad is easier said than done. Thankfully there are more than a few indications that can help you detect if your old bud is smokable or not. Marijuana gets its distinct smell from fragrant oils known as terpenes. They’re what give Blueberry its signature berry smell, Sour Diesel it’s funky fuel flavour, and Lavender its sweet floral aroma. As weed becomes old, it loses its scent as the aromatic terpene oils reduce in potency and the THC degrades.
So if your weed smells like anything other than weed, it’s a good enough indication that your bud is past its expiration date. Old weed is generally drier than weed you just scored, as with time the bud has been exposed to more light and heat thereby affecting its potency. However, there is a trick to identify if your green is still smokeable. Try pulling apart your stash, it should snap not crackle.
If it crackles chances are that the weed is too dry and will give you a harsh uncomfortable smoke without the high. Another trick to assess if your weed is smokable is inspecting its texture. Weed that has been kept for a while will most likely be crumbly on account of being dry and you may notice a white powder or layer covering the surface of the buds.
