Flower Storage: Guide to Harvest Preservation

Julien Bissonnette | November 17, 2022

Oxygen exposure, sunshine, and heat will diminish your flower's flavor and freshness. It's not your fault, though; it's challenging to determine the most effective flower storage strategies due to unreliable information, false beliefs, and the flower's pervasive stigma.

It's important to remember that preserving your flower is an essential factor. Before it can be used, the flower must be grown and dried, and harvest preservation and curing must be done. In addition, not storing optimally will negatively influence the quality of the product, which may affect the potency, flavor, and overall desired effects.

Since the days when someone would store their flower in a little plastic bag, we've gone a long way. Thankfully, jars have been in use for the past decade and more. However, we know those tiny baggies do very little to keep our flowers in good condition.

Even while storage technology has advanced dramatically, maintaining the freshness of your stock still requires some care and adhering to certain best practices.

Importance of Flower Storage

Your flower will worsen if you don't store it correctly over time. This holds for anything you grow from the soil, not just your buds; fruits, vegetables, tree nuts, etc.

Your seeds, however, don't always go bad or die, unlike many foods. The only possible outcome is a reduction in quality. Let's go over the various problems you might encounter.

Flavonoid and Terpene Degradation

When buds get older, their sense of taste and odor is among the first to diminish. The terpenes and flavonoids start to degrade, which is why this occurs.

This is simply the unavoidable, natural deterioration of your flower with time. But make sure you store your bud correctly to stop this from happening too fast and to guarantee that you appreciate the taste and smell characteristic of your buds.

Compound Breakdown

In addition to terpenes and flavonoids degrading over time, your buds may also lose the vital substances you've grown to know and love.

The quantity of the components in your flower will deteriorate over time, much like terpenes and flavonoids do.

The Physical Breakdown of Flower

In addition to losing the components in your buds, improper storage will also cause damage to the flower's anatomy and outward beauty.

For instance, you can anticipate your flower to dry out and crumble in your fingers if you don't preserve it in a suitable climate (hot, dry air) or direct sunshine.

Additionally, it will no longer be as colorful as it was when you first collected it. When you placed your flower in storage, it might have glistened with trichomes, covered in amber hairs, and occasionally tinted purple. However, if it is not preserved correctly, it will eventually become dingy, discolored, and unattractive.

How Long Does A Flower Last Before Degradation?

Breaking down your flower can't be helped, and it might make you wonder how long the flower lasts before this happens. This depends on how good your curing and drying process was. If the flower is still wet in the storage, you'll end up with bud rot.

On the other hand, overdrying your bud and keeping it in a jar for 3-4 months will make you disappointed in the taste and smell. To cure your flower thoroughly, you must burp your jars for the initial weeks to release excess moisture and allow fresh air inside.

If the curing and drying process is exemplary, your bud will last longer before breaking down. In the right situations, your flower can stay fine.

How to Preserve Flower

Use a Jar for the Best Flower Storage

Even when your flower is maintained correctly, mold can still grow, endangering not just the health of your buds but also negatively impacting your overall health. A flower exposed to or has begun to grow mold is no longer suitable for consumption.

A jar is an excellent tool for preventing mold growth on flowers. It may ensure your product is stored securely and guarded against increased humidity and unwelcome mold growth.

Storage Containers

The best flower storage containers stop trichomes from dropping off and safeguard your bloom from being disturbed. Additionally, they produce a closed atmosphere.

You could use a high-quality stainless steel or glass container, which would be much better. However, containers are made explicitly for holding the flower, and some have built-in functions. The containers are even more efficient because they can be used with humidification pods. For this purpose, the CVault Humidity Curing Storage Container would be your best bet.

Do Not Use Plastic Bags for Long Term Storage

As flowers become more well-known, the use of plastic bags for storage is being criticized by an increasing number of people. Plastic bags are the worst option if you want to store your flower buds for a long time. In contrast to a jar or container, they harm the trichomes on your flower and don't shield the buds from being disturbed while stored.

The primary issue with plastic bags is their high static charge, which makes it likely that the trichomes will become affixed to the plastic wall. Furthermore, flower storage in plastic bags for an extended time might negatively affect the flavor and aroma of your flower buds.


Consider Vacuum Harvest Preservation

Vacuum sealing is another convenient way to store your flower. This option is excellent if you have a lot of flowers and don't intend to use them for a long time.

A vacuum seal sucks all the air out of the bag and retains the same consistency and quality of the flower as when you sealed it.

You must keep it inside a closet or away from any light. This is essential because UV rays can still degrade the flower.

What About Freezing?

You can go and freeze your flower, but never use the refrigerator. While it seems that freezing a flower would offer benefits like slowing aging or keeping the buds solid, the contrary is true.

One of the most significant drawbacks of freezing a flower in a fridge is that the trichomes will likely become very brittle and break off. Freezing your flower could reduce its potency rather than preserve it.

Additionally, if your packing is not airtight, your flower may develop freezer burn, making defrosting difficult. Even under the most significant conditions, abrupt changes in humidity and temperature can make defrosting extremely stressful, increasing the likelihood that your flower could lose its flavor or draw viruses.

Ideal Harvest Atmosphere

The one thing to know about having the ideal harvest atmosphere for your flower is ensuring that there is never any direct sunlight on it while you store it. This will increase the speed of decaying specific compounds in your bud.

It's essential to ensure that the room where you store your harvest has a mild temperature. If the space is too hot, the breakdown of the compounds in your bud will speed up, drying it out and messing up the presence.

The ideal temperature for harvesting your flower is between 60-70 Fahrenheit, with the jar stored in a dark place like a closet or drawer.

Use Humidicants If Needed

Add humidicants to your flower if it has become dry from long-term storage to remoisturize it. Keep some Boveda packs on hand, just in case. Many gardeners have saved an overdried crop by putting it in containers with bags.


Flowers flourish when growers adhere to tried-and-true growing practices, such as maintaining a 40–50% humidity level, preventing cross-contamination, and ensuring that water has the proper pH for plants to absorb nutrients.

The Takeaway!

In the end, people frequently attempt to personalize it, develop their interpretation of flower cultivation, and claim it as their own.

However, suppose you adhere to the fundamental guidelines provided by Canada Grow Supplies and choose from the wide variety of flower harvest preservation products. In that case, you'll be a fantastic grower and have a successful run.
