Moldy Weed – How to Avoid It and How to Save Your Weed

Moldy Weed

If you have been growing or using cannabis for a while, you will probably have run into mold at some point –unfortunately. As with anything natural, your bud will start to develop mold if you aren’t careful with how you store or grow it. Luckily, there are ways to avoid mold and save your weed if it has already started.

Be careful with your lovely cannabis, it isn’t able to fight off molds by itself, but with the right care, there will be little chance of any mold getting hold of your prized buds. There is nothing worse than coming home to find your expensive product covered in mold. I bet many of us have even considered still smoking it mold and all, not I great plan I can tell you that! We have all been through this, so if you have come here because you have some moldy bud, don’t stress, you are going to be mold free in no time.


Sorting out your environment is one of the easiest ways to prevent mold. You know what they say; prevention is better than cure, so why wait for mold to start growing before thinking about it. Did you know that there are almost always spores just flying around in the air? Every breath you take, you are most likely breathing in spores. These spores are what cause molds – in the right environment. That is why you hear of people getting sick living in homes where there are molds growing in the walls.

Don’t let molds get a foothold in your bud, once they are there it is more difficult to remove and you will have to be a bit more serious in order to successfully clean it.

So what conditions do molds like to live in? Warm, moist, and stagnant areas are molded favorite. Generally, in summer, they grow a lot better, so if you have a grow room you are replicating the exact conditions for mold to grow. And on top of that, all of your plants or buds are releasing water into the air, meaning higher humidity levels. If you don’t properly monitor these conditions you could be at risk of a mold attack.

Even if it is warm and humid, it doesn’t necessarily mean you will get mold, especially if you have good air movement. Molds hate air movement and prefer areas that are undisturbed so that they can develop. If you have fresh air moving in and around your plants or bud, it is unlikely that molds will be able to start.

Keep your temps lower than 80 degrees and higher than 68 degrees and make sure humidity stays at the perfect level. I cannot tell you what that humidity level is with one number because it varies depending on whether you are growing or using. If you are growing, you are only likely to find mold during flowering and at this point, you want to drop your humidity levels to around 30% anyway – meaning you shouldn’t get mold if you have a proper setup. If you are curing or using your bud, be sure to monitor the moisture levels in your jars so that they don’t get dangerously high.

Check for Mold

During the lifecycle of your plants or your bud, you should continuously check it for mold, at least every day. You don’t need to be OCD and break open your buds to check inside every time, but a good check should be enough to know if things aren’t what they should be. Be on the lookout for any funny looking leaves and sections that aren’t looking healthy.

First you need to know what you’re looking for, otherwise, you could mistake some dank fuzzy bud for mold and trash your best nugs – not great. There are 3main types of mold relating to cannabis: white powdery mildew, bud rot, and fuzzy white mold.

Powdery mildew and fuzzy white mold start from the outside, making these two a lot easier to check for. Powdery mildew looks like someone sprinkled the white powder over your bud. It will usually start with a few white dots here and there, usually nearby each other.

Fuzzy white mold, also known as regular mold, is probably the one you can most easily identify. This is the mold that you would have seen if you left a fruit in the bottom of your bag for a few days during summer. It starts white and changes color over the life cycle of the mold.

One of the sneakier molds is known as bud rot because that is exactly what starts to happen to your lovely buds. It is difficult to spot because it starts in the center of the buds but if you inspect your buds you should notice it before it does serious damage. It looks similar to the regular mold in that it starts with the typical white moldy webbing. After this, it changes color as it grows until spores are produced as little black dots.

I have mold, what do I do?

Once you have mold, it’s full-on battle stations. You need to get that stuff separated from your other buds, ASAP. Cut away all the moldy parts, and be overly generous, you don’t want to miss anything. Unfortunately, when you have mold you don’t want to mess around trying to save a few grams. Scrap the moldy bud and save your harvest – that is the only way.

Once you have done that, you just need to refer to the other steps in this guide to make sure you continue to avoid cannabis molds and you should be good to go. If you have a bud that you are worried about, you can also remove any extra fat or sugar leaves. These leaves add to the moisture, so if it’s really bad you can give that plant an entire haircut.
