5 Ways to examine Your Weed for Mold

Nothing can kill a good buzz like weed that’s gotten moldy. It adversely affects its flavor, potency, and smell of your preferred strain. Moldy weed is caused by high humidity, lack of airflow, oxygen, and temperature. It can even cause health problems, so it’s essential that you know how to examine your weed. Basically, there are 5 ways you can examine your weed to see if it’s developed mold:

  • Feel it – healthy, properly cured weed should feel crisp and dry. If it has a damp or spongy feel, it may already be moldy. Detecting mold on marijuana plants takes due diligence and practice. Furthermore, it often involves the 3 tests – feeling it, looking at it, and smelling it. Thus, if you feel it is not right or smells slightly musty, it might have gone bad.
  • Look at it – the easiest and most common way to check for mold is to examine it with your naked. The most common signs to look for include:
    • cobweb-like material
    • dark spots on green buds
    • grey or yellow-looking fuzz
    • powdery appearance
    • slime
  • Look deeper – if you have microscope or can borrow one from somebody, you can easily detect the first hints of mold before you can see it with the naked eye. A jeweler’s loop or magnifying glass (the stronger, the better) can help you look deeper into the surface of your buds. Molds have structures that look nothing like any parts of a marijuana plant. If something doesn’t look right, you may be looking at mold.
  • Search online for marijuana recalls – although it’s a last resort, you can always check different grower’s websites or media outlets and check for recalls of moldy marijuana. Since issues like this typically go unreported, this might not be a reliable way to see if any moldy weed has made its way to the buyer’s market. However, it can be effective, especially if a particular crop was large enough and got distributed to multiple locations and numerous vendors.
  • Smell it – whether it’s berries, diesel fuel, or skunk, your weed gives of a range of aromas. However, if it smells like sweat or urine, it’s probably developing mold. That being said, some individuals have a more sensitive sense of smell than others and can detect more of the weed’s fragrance, even if it has gotten moldy. Keep in mind that some types of molds don’t develop a smell until they’re further along into their development. Thus, you might have to look at other signs to check the quality.
