There are several ways to tell if your cannabis is a little “off”. When cannabis has been taken over by mold, it’s pretty easy to spot. Just like bread or cheese, gray or white fuzzy mold are two of the most common culprits that will devastate your stash.

However, mildew can also look like a dusty white powder on fan leaves or parts of the bud. This white powder is aptly termed powdery mildew.

If you find moldy bud, don’t consume it. Dispose of it in an area where it will not contaminate other plants and make sure the mold has not spread to other buds.

Some things to look for in dried flower include:

  • Dampness
  • Musty, sweet, and stale odor
  • Grey or white fuzz
  • Specks of white powder, like white dust
  • Allergic reactions, pain, and heavy coughing after consumption

What does weed mold look like while growing?

Preventing mold starts in the grow room or greenhouse. Maintaining appropriate temperatures, carefully controlling humidity, and reducing contamination risk by keeping the area clean and free of diseased plants is a must.

Recognizing the early stages of molds and mildews can save your entire crop, as well as improve the safety for the end consumer.

Here are some basic things to look for while you’re growing:

  • White powder developing on leaves
  • Fuzzy white or gray hairs on buds
  • Yellowing, dying, drooping leaves (could be a sign of root rot)
  • While or gray fuzz in soil
  • Musty, stinky roots
  • Discolored or dying roots
  • Musty smelling buds

How to reduce the risk of smoking moldy weed

It’s important to note that small traces of molds and mildews can be present on your cannabis even if it is not visible. For some, this trace amount of mold exposure is enough to cause illness or allergy.

The best way to reduce your risk of inhaling mold is to purchase laboratory-tested cannabis from a regulated access point.

Unfortunately,  global legal restrictions on the cannabis industry mean that millions of people lack access to quality-tested recreational and medical cannabis. Often illicitly produced, cannabis buds can retain residual pesticides, fertilizers, fungicides, and pathogens.

Here’s how to reduce your risk of smoking moldy cannabis:

  • Pick buds that smell delicious to you, that don’t have musty undertones
  • Don’t pick buds that feel damp, or have a wet, grassy scent
  • Don’t consume cannabis that you know has been out in the rain or has gotten wet
  • If growing, put up a greenhouse before weather gets bad and make sure it’s humidity controlled
  • Properly store your cannabis in air-tight containers in a dark, dry area
  • Keep grow rooms clean
  • Use a humidity pack while storing your bud
  • Give your bud a once-over before consuming
  • Pick laboratory tested cannabis whenever possible
