Why Do My Buds Have No Smell?

Growing weed at home has only become more and more popular in recent years. There are many advantages to growing and harvesting your own buds and many setups to choose from to suit your own needs.

However, one problem that many home growers run into all too frequently is a bad smell coming from their fresh buds. A bad aroma can ruin the quality and enjoyment of your weed, even negatively affecting the perceived taste. 

Worse, sometimes your buds could be entirely devoid of any smell at all – a surefire sign that something is not right.

So, what do you do when weed doesn’t smell like weed should? In the following, we will go over just that, showing you everything you need to know on how to bring that fine smell back to your weed.

Importance of Terpenes

To understand what causes a foul smell or taste in weed, we first have to understand what makes buds smell so good when they’re grown right.

The answer lies in one word: terpenes. In short, terpenes are a group of organic compounds created within the trichomes – those fine fuzzy hairs that you can see growing all over the hemp plant. They are shared with many other kinds of plants and are not unique to cannabis (though not all terpenes are found in every plant species).

Terpenes affect both the aroma and the taste of weed, but their role goes far beyond that. If you’ve ever read up on the science of weed and how it interacts with our brains, you’ve probably heard of something called the entourage effect. 

This is when the right combination of compounds and ingredients provides a larger effect than any of these ingredients would be capable of in isolation. In other words, weed quite literally is more than the sum of its parts.

This applies to terpenes as well! Not only do they determine the taste and smell of our weed, but by interacting with cannabinoids such as THC, they do affect how our weed makes us feel.

This is why it should be every weed grower’s imperative to maximize their crop’s smells and make sure that they turn out right. Otherwise, it might make for an underwhelming experience when your buds are ready for consumption, and we sure wouldn’t want that!

Nutrients and Supplements

The biggest cause of poor-smelling buds is interfering with the cannabis plant’s natural growth pattern. Many attempt to make their cannabis grow quicker, fuller, or otherwise improve its characteristics by enriching it with nutrients and growth supplements.

This is generally a bad idea unless done in cautious moderation. Too many added nutrients can cause the buds to lose their natural color, which can affect the smell. If this is the case with your buds, you might also note a foul taste, a key sign of excess nutrition.

When feeding your plants nutrients, it’s essential not to overdo it and stick to the recommended amount.

Early Harvesting

Another reason why your buds might not be smelling as they should is because you harvested them much too early. When this happens, the terpene count in the cannabis is abruptly cut off and will remain low even as you cure your harvest.

It is crucial to time your harvest right by watching for key signs of maturity in your plants.

As the cannabis blooms and enters its final growth stage, you should be able to see the buds becoming more visibly solid. The trichomes will also darken a little bit and curl or kink in a certain way instead of continuing to grow out straight.

When you notice these signs (in addition to an ever-increasing smell), it’s the right time for harvesting your buds.

High Temperatures When Drying

Many home growers report a particular kind of bad aroma is a so-called “hay” smell, which is undetectable until harvesting but becomes more and more noticeable after drying.

In the majority of cases, this is down to improper drying techniques. The single biggest thing you can do to make your buds dry in a healthier manner is to hang them evenly in a space that has plenty of fresh air and is well-ventilated. Otherwise, the inside of the bud can dry faster or slower than the outside, resulting in a foul smell.

Likewise, temperature plays a critical role during the drying stage. A drying space that is too hot and doesn’t have enough air circulation is the perfect environment for mold to grow on your weed – which does not only ruin its smell but can also make your buds uncomfortable to smoke!

Curing for Maximum Smell

After drying, there is one step that many inexperienced growers often forget: curing weed to really bring out that smell. With many strains and under many environmental conditions, even if you do everything right up until drying, your buds might still come out smelling a bit weak.

Properly curing marijuana ensures a stronger, healthier smell and can even improve potency – and it’s better for the plant’s health too!

We recommend the old-school method that has stood the test of time: curing your weed in glass jars. A simple set of mason jars will do!

Just separate your buds and fill each jar up to three-quarters of its full volume. Seal, and let the buds sit and cure for at least a few weeks.

During this time frame, it is important to periodically check (at least daily) each jar for humidity levels. You don’t want your buds to be drowning, so open the jar for at least a few minutes and up to an hour or two as necessary whenever you see too much water.

Generally, you want to keep humidity levels between 55 and 62 percent – there are specialized humidity packs that can help you maintain that rate.

Shorter Curing Period

If you did cure your buds but are still noticing a foul smell (or none), you probably did not let the curing period run its full course. Buds need at least four weeks to be fully cured; in some cases, even more! 

Trace amounts of humidity leftover after drying and curing can not just invite mold but also inhibit terpenes, thus causing a poor aroma and taste.

Best Way to Store Weed

Both for curing and long-term storage, you need to make some basic considerations if you want your weed to maintain its strong smell and potent effects.

Weed’s biggest enemies are UV rays, moisture, heat, and high oxygen. The most convenient way to ensure that all of these are kept to a minimum is to do what we already suggested above – keep your buds in sealable, airtight mason jars stored in a cool and dark place!

This way, you can ensure minimal terpene loss and provide the optimal conditions for strong-smelling, fine-tasting, and heavy-hitting weed.
