What You Lose When Terpenes Evaporate After Harvest

Saving terpenes post-cure is tricky. All of the hard work cultivators put into their grow-op can be compromised once the flower is sold and leaves their hands. What was once premium cannabis can quickly and easily become subpar at any point during its journey to the customer. And once terpenes evaporate after harvest, it adversely affects how much cannabis is worth as as well as its quality.


Maintaining the fragrance, flavor and effects of top-shelf cannabis means saving terpenes—those organic chemicals found in cannabis that give flower its vibrant aroma and distinctive taste. Without protection, terpenes begin to evaporate immediately when cannabis is in bins, out for distribution and on the shelf. And when terpenes are gone, it’s permanent.


Without a terpene shield in bins, bags and packaging, cannabis flower loses 40% of its terpenes—along with desired aromas, flavors and effectiveness. Fewer terpenes mean a low quality product and poor customer experience with a brand. What company wants its name on cannabis whose quality drops nearly in half?


Just keeping flower from drying out isn’t enough. To deliver a full terpene experience to consumers, cannabis processors use Boveda, the original terpene shield, to protect cannabis after harvest.

Only Boveda offers a monolayer of purified water that protects terpenes from evaporation and degradation. Boveda’s patented salt water solution in the packaging membrane works quickly and precisely enough to create and maintain this monolayer shield faster and longer than any other product on the market.

When terpenes are protected by a monolayer shield of purified water over the trichome, cannabis maintains its full terpene effect. And cannabis maintains quality and value.


A monolayer of water around a trichome shields terpenes and prevents terps from evaporating.


Evaporation post-cure means lost profits. When flower’s moisture weight begins to evaporate, the economic value of the whole harvest drops and affects a producers bottom line.

How much does evaporation cost you after harvest?


“People focus on growing the plant but they forget about the post-harvest which is integral to the process,” Matt Christopherson, VP of Business Development & Partner at Twister Trimmers, said.

Everyone knows mature buds must be dried and cured before they can be smoked or vaped. But there’s a fine line between achieving an optimal cure and over-drying a harvest. When too much water dissipates from flower, its quality and potency suffer. This ultimately puts the cultivator at risk resulting in a poor quality product and a damaged brand reputation in the market. Not to mention—the drier the flower, the lighter it weighs. So you do the math.

Cultivators can’t afford to slip in today’s highly competitive cannabis field—trip up and savvy consumers move on. Producers must combat moisture evaporation like the plague that it is. The results speak for themselves: the brand is saved, the investors are happy, the customers are happy.

“In the simplest terms, Boveda makes my flower very, very happy, protecting it, maintaining the terpenes, flavor, smells and effects of my favorite CBD strains.”


Unprotected Inventory = Death to Terps

When legal adult-use markets come to town, thirsty consumers buy just about anything—at first. Cultivators find themselves processing more flower to meet greater demand. As a result, more product is stored in inventory.

If cannabis inventory isn’t protected by a terpene shield, evaporation is death to terpenes. As moisture content is lost, so are the terpenes and cannabinoids that provide aroma, flavor and effects. So carefully grown and cured cannabis may be compromised before it even leaves a facility.

Consumers Want Their Terps

Since 2012, adults in Washington state have been able to legally buy and consume cannabis. And some Washingtonians are none too happy about the product they’ve purchased. Origins Cannabis, a premier dispensary in Seattle and Redmond, wanted to find out why.

Origins ran a campaign asking people to bring in empty cannabis containers from flunky flower—whether they bought it at Origins or not. The consumers filled out a quick iPad® survey to review the product.

“It would help us understand what they didn’t like,” said Jon Sherman, who runs Origins along with business partner Andrew Cornwall. “We were blown by what the results were. It was because their product was too dry. ”

Drew Emmer, who works with companies to integrate Boveda into cannabis production, isn’t surprised. “What was once considered a ‘seed to sale’ supply chain is now actually ‘seed to satisfaction’,” Drew said.

Selling harvested cannabis is no longer the end of the road for cultivators. Now that cannabis is becoming legal, regulated and competitive; cultivators now need to take into account customer satisfaction and post purchase factors.

As markets mature, so do consumers’ palates. Customers now recognize the affects of lost terpenes. When aroma, flavor and experience are not up to par, they buy more of what they like and skip brands that disappoint them.

Businesses that care about maintaining a higher standard and saving terps use Boveda in their storage and packaging because they know it elevates their brand’s quality and consistency. With Boveda, every cannabis company can guarantee a full terpene effect when consumers smoke their cannabis. There’s no aroma more enticing than a fragrant flower in full bloom. Only Boveda protects terpenes until consumers buy flower, grind flower and inhale flower.

How’s Your Flower By the Time It Reaches the Consumer?

Cannabis needs a Boveda humidity pack to save terpenes and protect cannabis from drying out.

Cultivators are so precise about flower’s growing environment—the soil, temperature, light, moisture, etc. Why after weeks of carefully cultivation do growers and processors store cannabis without a terpene shield?

Cannabis is a thriving business. Successful cultivators focus on technique, innovation and final product. Vertically integrated producers are adding Boveda to every vial, jar or bag before sending flower to market. When cultivators take proper steps to add a terpene shield to their end product all the way through the supply chain, their companies will output consistently quality product. And quality product attracts consumers, fosters trust and builds brand loyalty.

Cannabis brands and businesses set themselves apart in a competitive market use Boveda, the original terpene shield.

Storing and packaging flower with Boveda 2-way Humidity Control:

  • Continues to refine aroma and flavor
  • Retains terpenes and cannabinoids
  • Controls evaporation once product leaves the cultivator
Cannabis companies, like Buena Vista, save terpenes and protect the quality of their product like these pre-rolls by co-packing with Boveda.
