Cannabis offers cues when it’s time to harvest – along with historical data and testing
Nic Robertson, vice president of operations in Massachusetts for 4Front Ventures, said commercial growers have moved away from eyeballing the color of trichomes and squeezing buds to gauge moisture content in favor of scientific methods to evaluate when cannabis flower has reached an optimal point for harvest.
“Over the last seven or eight years, I have been proven wrong by my aesthetic view of how mature I think that plant is at that time,” Robertson said.
“Getting those test results and showing higher levels of CBGA – the precursor to a number of other cannabinoids – than I would have expected indicates that that plant could have gone another few days or another week before it truly reaches its maximum potential.”
Today’s cannabis cultivators have more scientific approaches to decide when their crops are ready to harvest, such as rigorous data collection, frequent testing and tools such as microscopes and moisture meters.
History as a guide
“Once we first grow something, we figure out how long it takes to finish. Is it eight weeks, nine weeks, 10 weeks?” said Kevin Sparks, lead cultivator for Insa’s operations in Pennsylvania.
Knowing the window when a strain historically finishes helps cultivators plan their harvests months in advance – or even at the start of the growing year, Sparks explained.
Robertson agrees that keeping a detailed history is important, adding, “We are always learning from the crop.”
If a strain from the previous crop finished on day 58, then the strain from the ensuing crop likely will finish on or very close to day 58, assuming “everything goes to plan for the next crop,” Robertson said, “and there were no stressors that would cause the plant to finish early or cause the plant to delay and finish late.”
That’s a big “if,” however.
“Oftentimes those crops are not exactly duplicated. Certain things are out of our control,” Robertson said.
In commercial settings – especially large or medium-sized grows where production schedules require crops to be flipped five or six times per year – cultivators often must decide between the perfect and the good.
“Every harvest that we do is based on the harvest that is right before and the harvest that we’ve scheduled right afterward. So, we only have a small window of time that we can say, ‘OK, we’re going to pull these plants a little early, or we’re going to give them a few extra days without that domino effect being introduced into the rest of the schedule,” Robertson said.
“Some connoisseurs might raise their nose to this, but over time, I have noticed there’s not a massive difference in a two-day window.
“If it works better for our labor scheduling to harvest on a Friday rather than having to call 25 people in on a Saturday, I’m harvesting the room on Friday.”
Sampling and science
For some cultivators, another important method to help decide when plants are ready to be harvested is sampling – or pinching off a small piece of flower and testing its cannabinoid profile and potency at that point in time.
Marco Malatrasi, chief cultivator at Florida-based Fluent Cannabis, uses samples to help determine the “ripening curve” for his crops and evaluate how plants in a certain crop are progressing toward harvest.
“For the ripening curve, you need quantitative measure. From your batch, you pull down one plant in week seven, eight, nine and 10, if you have it … taking samples all through the ripening process as you get closer and closer to that harvest date,” Malatrasi said.
He added that you don’t need to sample whole plants but, rather, small buds from different parts of the grow room (back, front, center, edges) and different parts of the plant (top, middle, bottom).
“I’m testing for what’s going to end up in the jar,” Malatrasi said.
He does the sampling twice a week because “big changes” to the cannabinoid profile and potency can occur in only three days – and changes are more likely as you get closer to the end of the cycle.
By testing those different samples, you can see “how they are doing chemically” Malatrasi said.
“Everything that we’re looking for is in the ripening curve and finding that sweet spot of when to harvest. … If you still have a lot of CBG, a precursor to THC, you’re probably still early. If you have more-than-usual CBN, you’re running late,” Malatrasi said.
His preferred measuring instrument is high-performance liquid chromatography (HPLC), but that can be expensive. Less expensive tools exist, such as Purpl Pro, a handheld potency tester, and a tabletop potency-testing apparatus from Orange Photonics.
Using these instruments, growers can study marijuana flower’s cannabinoid profile.
“Principally, you’re looking for CBN and CBG, because one’s a precursor and one’s after the fact. That’s cueing my potential. For example, if I do a reading at week seven and I have a certain THCA percentage, that’s great, but how do I know it’s going to increase? Well, that’s where I’m looking at the CBG percentage,” Malatrasi explained.
It’s also important to look at trichome density. For that, Malatrasi likes to use a microscope and a so-called Secchi disc.
“You can use them in the field. They’re good, thorough and quick, which is important when you’re harvesting a few thousand plants per week,” Malatrasi said.
When inspecting trichomes, cultivators favor those with big, bulbous heads and – in terms of extraction purposes – those that have long stems that make them easier to knock off.
It’s also important that there be a high density of trichomes on the flower and that their color be what growers typically describe as “milky.” Too clear, and they are underripe; too milky or amber in color, and they are getting overripe.
For research and development purposes, Malatrasi often will “sacrifice” one or two plants by letting them become overripe because it tells him when “the plant starts to fall off.”
But taking samples to test before harvest might be complicated in some states because of their seed-to-sale tracking systems and compliance requirements.
“We have to track each individual plant separately, so it becomes really hard to, say, take one little chunk off the plant and then weigh that and then track the rest of it separately,” Robertson said.
“It creates this compliance risk, and it’s just a nightmare of data for us to maintain that. So, we harvest the plants full, and we dry those plants in a full-plant hang that are still individually tracked by RFID (radio frequency identification) plant tags.”
Jushi’s evaluation processes at all of its cultivation sites include “harvest walks” throughout the harvest room, bringing together leaders from the site’s cultivation and processing departments “and even maybe a manufacturing individual,” said Ryan Cook, executive vice president of operations at Jushi.
“These reports guide us … so Josh (Malman, Jushi’s head cultivator) and I can have conversations weeks in advance of any harvest and generally know where things are headed,” Cook said.
“We have our own analytical labs and our own microbial labs inside the facilities, so we have the ability to test far in advance. That allows them to gauge the potencies weeks before we’re prepared to harvest.
“We’ve got full-on harvest prediction planners, where we can see from the clones that I took this week when that plant is going to be harvested. And ideally, we’re working in a way that we say, ‘Hey, in 16 weeks, I need half of that product going to flower and half that product only to extraction,’” Cook said.
“We are able to make some adjustments at the end of cycle near harvest based on measurement, but we try to make those determinations earlier.”
Wrapping up
While scientific measurements are a much larger part of cannabis harvesting than they used to be, the old-school tricks that once informed growers aren’t necessarily obsolete.
Whether you’re using an HPLC machine, a microscope or jeweler’s loupe to examine your plants, you are still looking for the same visual cues.
“When you know it’s done, it’s usually by trichrome production,” said Frank Golfieri, chief cultivator for Insa’s Massachusetts operations.
Flower to be used for fresh-frozen extraction is best harvested slightly on the early side, when the trichomes are clear to a little milky. Earlier means that there are more terpenes because fewer terpenes have been lost to heat.
If you harvest for flower, wait a few days longer, when the trichomes are milkier, Golfieri recommends.
All of Jushi’s cultivation facilities are equipped with digital microscopes that can take high-resolution photos of trichome size, shape, color and density.
“The age of the plant and what the trichomes look like is absolutely something we’re going to look at before we harvest,” said Malman, Jushi’s head cultivator.
“We’re looking at pistil retraction near the end of the cycle. You normally see these big, white fuzzy pistils. … As those start to get older and more mature, they will start to retract down into the calyx.
“Sometimes they change color … orange or brown. Sometimes they don’t, they just fully retract. Those are visual cues that we look for.
Jushi also watches “the color of the flower as we’re dropping that temperature near the end of the cycle. Both in a daytime and nighttime period, you start to see more purples, more anthocyanins coming out in the plant. So that’s generally a cue for us,” Malman said.
Golfieri agreed: “If (the hairs) are all white, it’s still too early to cut down. You want them to be orange. And the flower should have a velvety, sticky feel. If the hairs are red and some new white ones are sprouting up, that means you’re feeding it too much nitrogen,” he said.
Off-gassing aroma also is a sign that plants are ready to be harvested.
As the end of cycle approaches, cultivators should lower flower-room temperatures “to preserve as much of that off-gassing as possible,” Malatrasi said.
“If you already have off-gassing, then it’s probably time to get the plants harvested. I want off-gassing to occur in the dry room.”

New Mexico cannabis operator fined, loses license for alleged BioTrack fraud
New Mexico regulators fined a cannabis operator nearly $300,000 and revoked its license after the company allegedly created fake reports in the state’s traceability software.
The New Mexico Cannabis Control Division (CCD) accused marijuana manufacturer and retailer Golden Roots of 11 violations, according to Albuquerque Business First.
Golden Roots operates the The Cannabis Revolution Dispensary.
The majority of the violations are related to the Albuquerque company’s improper use of BioTrack, which has been New Mexico’s track-and-trace vendor since 2015.
The CCD alleges Golden Roots reported marijuana production only two months after it had received its vertically integrated license, according to Albuquerque Business First.
Because cannabis takes longer than two months to be cultivated, the CCD was suspicious of the report.
After inspecting the company’s premises, the CCD alleged Golden Roots reported cultivation, transportation and sales in BioTrack but wasn’t able to provide officers who inspected the site evidence that the operator was cultivating cannabis.
In April, the CCD revoked Golden Roots’ license and issued a $10,000 fine, according to the news outlet.
The company requested a hearing, which the regulator scheduled for Sept. 1.
At the hearing, the CCD testified that the company’s dried-cannabis weights in BioTrack were suspicious because they didn’t seem to accurately reflect how much weight marijuana loses as it dries.
Company employees also poorly accounted for why they were making adjustments in the system of up to 24 pounds of cannabis, making comments such as “bad” or “mistake” in the software, Albuquerque Business First reported.
Golden Roots was fined $298,972.05 – the amount regulators allege the company made selling products that weren’t properly accounted for in BioTrack.
The CCD has been cracking down on cannabis operators accused of selling products procured from out-of-state or not grown legally:
- Regulators alleged in August that Albuquerque dispensary Sawmill Sweet Leaf sold out-of-state products and didn’t have a license for extraction.
- Paradise Exotics Distro lost its license in July after regulators alleged the company sold products made in California.
Golden Roots was the first alleged rulebreaker in New Mexico to be asked to pay a large fine.

Marijuana companies suing US attorney general in federal prohibition challenge
Four marijuana companies, including a multistate operator, have filed a lawsuit against U.S. Attorney General Merrick Garland in which they allege the federal MJ prohibition under the Controlled Substances Act is no longer constitutional.
According to the complaint, filed Thursday in U.S. District Court in Massachusetts, retailer Canna Provisions, Treevit delivery service CEO Gyasi Sellers, cultivator Wiseacre Farm and MSO Verano Holdings Corp. are all harmed by “the federal government’s unconstitutional ban on cultivating, manufacturing, distributing, or possessing intrastate marijuana.”
Verano is headquartered in Chicago but has operations in Massachusetts; the other three operators are based in Massachusetts.
The lawsuit seeks a ruling that the “Controlled Substances Act is unconstitutional as applied to the intrastate cultivation, manufacture, possession, and distribution of marijuana pursuant to state law.”
The companies want the case to go before the U.S. Supreme Court.
They hired prominent law firm Boies Schiller Flexner to represent them.
The New York-based firm’s principal is David Boies, whose former clients include Microsoft, former presidential candidate Al Gore and Elizabeth Holmes’ disgraced startup Theranos.
Similar challenges to the federal Controlled Substances Act (CSA) have failed.
One such challenge led to a landmark Supreme Court decision in 2005.
In Gonzalez vs. Raich, the highest court in the United States ruled in a 6-3 decision that the commerce clause of the U.S. Constitution gave Congress the power to outlaw marijuana federally, even though state laws allow the cultivation and sale of cannabis.
In the 18 years since that ruling, 23 states and the District of Columbia have legalized adult-use marijuana and the federal government has allowed a multibillion-dollar cannabis industry to thrive.
Since both Congress and the U.S. Department of Justice, currently headed by Garland, have declined to intervene in state-licensed marijuana markets, the key facts that led to the Supreme Court’s 2005 ruling “no longer apply,” Boies said in a statement Thursday.
“The Supreme Court has since made clear that the federal government lacks the authority to regulate purely intrastate commerce,” Boies said.
“Moreover, the facts on which those precedents are based are no longer true.”
Verano President Darren Weiss said in a statement the company is “prepared to bring this case all the way to the Supreme Court in order to align federal law with how Congress has acted for years.”
While the Biden administration’s push to reschedule marijuana would help solve marijuana operators’ federal tax woes, neither rescheduling nor modest Congressional reforms such as the SAFER Banking Act “solve the fundamental issue,” Weiss added.
“The application of the CSA to lawful state-run cannabis business is an unconstitutional overreach on state sovereignty that has led to decades of harm, failed businesses, lost jobs, and unsafe working conditions.”

Alabama to make another attempt Dec. 1 to award medical cannabis licenses
Alabama regulators are targeting Dec. 1 to award the first batch of medical cannabis business licenses after the agency’s first two attempts were scrapped because of scoring errors and litigation.
The first licenses will be awarded to individual cultivators, delivery providers, processors, dispensaries and state testing labs, according to the Alabama Medical Cannabis Commission (AMCC).
Then, on Dec. 12, the AMCC will award licenses for vertically integrated operations, a designation set primarily for multistate operators.
Licenses are expected to be handed out 28 days after they have been awarded, so MMJ production could begin in early January, according to the Alabama Daily News.
That means MMJ products could be available for patients around early March, an AMCC spokesperson told the media outlet.
Regulators initially awarded 21 business licenses in June, only to void them after applicants alleged inconsistencies with how the applications were scored.
Then, in August, the state awarded 24 different licenses – 19 went to June recipients – only to reverse themselves again and scratch those licenses after spurned applicants filed lawsuits.
A state judge dismissed a lawsuit filed by Chicago-based MSO Verano Holdings Corp., but another lawsuit is pending.
