Moldy Weed: How to Spot It


How to Spot Moldy Weed Symptoms in Your Stash

Moldy weed symptoms are not unlike the symptoms of any other consumable, perishable product you have at home. When your bud is exposed to too much moisture, mold and mildew have a chance to flourish on the surface or in the nooks and crannies of the flower. While some people opt to take their chances and smoke a bowl of moldy bud, it should go without saying that this can put you at risk for fungal lung infections and allergies.

Here are the moldy weed symptoms to look for the next time you’re about to break down a nug.

Moldy Weed Symptoms

What does weed mold look like? Moldy formations on your bus are going to resemble the type of growth you might find on food that’s past its prime. Furry and fuzzy white, grey, or greenish growth are dead giveaways for the state of your stash.

While a heavy coating of trichomes can certainly make your bud look furry, don’t mistake these resinous deposits for mold. Tantalus Labs points out that trichomes are going to feel like resin and cover the bud pretty evenly. Mold, on the other hand, will be unevenly distributed over your nug, will feel like fur, and will form on top of trichomes.

Mildew Formation

Mildew is mold’s powdery cousin. White in color, powdery mildew resembles a patch or coating of dust on your afflicted bud. If your flowers are covered in this form of fungus, take care not to stir up the dust while you’re handling them; the particles are small and can easily be inhaled, whether or not you’re smoking them.

A save that occasionally crops up on bud user forums is a technique that turns your powdery buds into hash for edibles, using a fine filter to save the trichomes while washing away mildew particles. While this fix will certainly appeal to heads reluctant to toss out theoretically smokable bud, we recommend waiting for scientific confirmation, or at least an industry consensus, that this works. It’s common practice to wash off mildew from flowers and leaves during cultivation, but this only works before the trim is dried and cured.

The Nose Knows

Smell is another sense that will help you in the process of how to tell if your weed is moldy. If you’ve smelled mold before, you’ll be able to recognize the same musty, stale notes lurking among the finer odors of your particular strain of flower. Again, take care not to inhale any powdery mildew if you’re taking a whiff — though, if you’re able to smell mold and mildew, it means that it is making its way into your lungs.

Other Signs That Your Weed Has Got to Go

Beyond smelling damp or grassy, being able to feel dampness or moisture on your weed should also tip you off that it has taken a turn for the worse. An even more troubling sign is if you’re experiencing symptoms of mold and mildew exposure, including allergic reactions, wheezing, and asthma following a smoke sesh.

Prevent Mold from Happening

You won’t be able to salvage your weed once it becomes damp and moldy, so do everything you can to prevent it from getting that way in the first place. Keep your stash stored in airtight containers in a dark, dry space. Avoid exposing your flowers to moisture. If they do get wet, immediately set them somewhere where they will have plenty of air circulation — perhaps on top of a baking sheet — so that they can dry out; examine them before smoking.

Sometimes, moldy weed is just out of your control. If the flowers were not dried and cured properly by the grower, or if they were stored improperly by the supplier, your purchase can already be hosting mold and mildew. Let your dispensary or dealer know if you come across moldy weed so that they can trace the issue back to the source.
