How to Harvest Cannabis Plants
Once you have followed all the correct steps to ensure healthy vegetative growth and vigorous flowering, the next step is to harvest your mature plants. This article provides a basic set of guidelines on when to harvest, how to harvest and what to do with your freshly-harvested flowers.
When should you harvest cannabis plants?
To harvest successfully, you should know the exact date that your plants started flowering. If you don’t know the exact date, then you should at least have an approximation. This knowledge will give you a rough idea of how long your plants will need to flower, and from that you can work out the approximate expected date that you will harvest.
Flowering times for cannabis vary greatly according to strain. Indica-dominant varieties generally finish early, in as little as seven or eight weeks after flowering begins, while sativa-dominant strains may require substantially longer—up to 24 weeks in some extreme cases. The majority do not require such long flowering times (10-12 weeks is generally the longest most growers are prepared to wait), and there are also numerous sativa-dominant commercial hybrids that will finish in under 10 weeks.
When trichomes are clear (yellow arrow) they are immature; when they are cloudy (red arrow) THC levels are high, when they are amber (green arrow), THC has begun to degrade to CBN.
However, knowing the approximate requirements of your chosen strain may not be sufficient to judge whether your plants are ready for harvest. A useful technique is to assess the percentage of white hairs that have changed colour (usually to a brownish-orange, though some strains may have pinkish or purplish hairs). Plants should not be harvested until at least 40% of hairs have turned.
THC levels are often highest if harvesting when 40-70% of hairs have changed; if you continue to wait past this point, THC will begin to degrade to CBN. This may cause the effect of the finished flowers to be more soothing and less likely to induce anxiety. This process where THC degrades to CBN also occurs after harvesting and during decarboxylation.
It is also possible to assess maturity by using a magnifying glass to observe trichome colour. If clear, plants are immature; if cloudy, THC levels are at their maximum, and if amber, degradation has begun to occur.
How should you prepare yourself for the harvest?
Before commencing the harvest, ensure that you are equipped with the following:
- A pair of good quality rubber (powder free) or latex gloves
- A sharp, clean pair of scissors or shears
- A large plastic tray or tub in which to place cut branches
- Some twine or string you can use to attach your branches to hang and dry
- Something to hang the branches from, such as a clothes line, wardrobe dowel etc.
Note that the gloves will prevent sticky resin from adhering to your hands and will enable easier collection of the resin in case you want to make hashish. The blades of your cutting tool will also collect resin, which you can then scrape off and produce hashish. This is why it’s important that your scissors or shears are clean when you start using them!
It is better to cut branches separately to allow better airflow when drying, rather than keep plants whole
Seeds EARLY HARVEST WORLDOFSEEDS
Our Early Harvest varieties are fast flowering varieties, femnized and photodependent and are the result of the crossing of an autoflowering F4 with photodependent varieties of our catalog with what we manage to shorten their flowering and strengthen their vegetative growth stage, which turns them into varieties ultra-fast. These plants can be ready for harvest, from seed, in about 8 weeks in total, which makes them ideal for crops in wet, rainy areas and very harsh winters, as their speed allows you to anticipate the attacks of the majority of fungi.

The Importance of Collecting and Harvesting Cannabis Seeds
T here was a time in our not-too-recent history when a sack of weed almost always included seeds. However, as cannabis cultivation evolved, so did the demand for sensimilla, or high-quality, seedless cannabis. Breeders not only began developing their own customized strains, they also started specializing in the cultivation of very special cannabis seeds. These seeds are used in both the breeding process and the wide-spread distribution of the carefully created strain itself.

The Role of Seeds in the Breeding Process
The process of breeding the perfect strain requires a controlled production of seeds. Breeders must force their favorite plants to produce pollen and then use it to pollinate other favorite strains, thus creating “cross-breeds” of their two selected parents. Note that this process is not haphazard like the seeds one might find in a poorly-controlled outside marijuana grow – cannabis seed cultivation is a precise process that requires controlled, sanitary environments that are thoroughly sealed to prevent outside dander from getting in.
The plants can “veg” here, or continue their vegetative growth phase if trying to increase their size before seed production begins, but it’s not necessary. Once the plants are large enough, they are put into a flowering light cycle of 12 hours light and 12 hours of complete darkness.
Within a few weeks, the male will produce pollen sacks which will soon burst and get carried off into the air to pollinate the females. The females will now produce seeds which may continue to be used in the breeding process or harvested and sold to the public.
For the purpose of seed production, only around 20 females are recommended per male. However, a single male can realistically pollinate hundreds of females, hence the importance of a tightly sealed environment during the seed production process.
Natural Cannabis Seed Production
Cannabis is an amazingly resilient plant and doesn’t require male pollination to produce seeds. Evolution has bestowed upon the cannabis plant an amazing ability to self-pollinate when there are no males around to do it for her. Whether stressed or old (for example, a female cannabis plant that is not harvested before her prime), if a female senses an environment that is not conducive to long-term growth, she will produce seeds in hopes that her legacy will continue.
This is how feminized cannabis seeds are produced. Breeders will carefully stress a healthy female plant to “trick” her into thinking her life or safety is in danger.
One common method is to stress the female by applying solutions like colloidal silver or silver nitrate generously onto the leaves when she first enters the flower light cycle. Within 3-4 weeks, male sex organs will appear on the nodes of the female plant. Please note, applying these stress-inducing solutions to plants renders them unsmokable. The particulate cannot be washed off thoroughly because it settles deep into the surface of the plant. This method is for seed production only.
Another method is to simply let a healthy female age. If she grows past maturation, she will produce male “banana” pollen sacks without any male chromosomes. Though she may look like a hermaphroditic plant at this point (one containing the chromosomes of both male and female), the pollen she produces will contain only XX chromosomes and therefore cannot pass the Y (male) chromosome down to its heirs. Pollen collected in this way is then used to pollinate another female which will then produce female-only seeds.
How to Collect Cannabis Seeds
Though many grow ops aim to do away with seeds to grow fine sensimilla instead, sometimes breeders want seeds. Whether to grow their own crops or to sell to a demanding public, cannabis seed cultivators have their goals set on producing healthy, happy seeds in lieu of big, beautiful buds.
Seed crops are harvested when the seeds are plump and dark, often with a tiger stripe appearance (around six to eight weeks into flowering).
After harvesting, the bud is dried and the seeds are collected. Small-scale seed collection is done by simply crumbling the cannabis flower and collecting the seeds that fall out (this video by Johnnys Green Extractions offers a clever way to separate seeds from flower using an old vinyl record cover).
Commercial seed collection usually involves special machines that crush dried flower then pass the trim and seeds into separate bins. After seeds are collected, they’re stored in opaque, air-tight containers to prevent them from rotting or sprouting prematurely.
Though cannabis flower is usually cultivated to be seedless, sometimes the seeds are the whole point. Breeders pay special attention to the pollination, harvest time, and drying process when growing cannabis specifically for the seeds to improve the likelihood of a successful harvest.
Frequently Asked Questions
How are Feminized Seeds Made?
Feminized seeds are made by inducing a female plant to produce seeds without being pollinated by a male. These resulting seeds will not contain a male Y chromosome, only retaining the two X chromosomes from the female plant, and thus all of the resulting seeds will be female. This process can be done by stressing the plant, altering it with chemicals, or allowing it to grow past its harvesting time.
How Many Plants Can a Male Cannabis Plant Pollinate?
For professional production, it is recommended to pollinate about 20 female plants per male plant, but this is done to ensure tight oversight and quality control. In the wild, a single male plant can pollinate hundreds of female cannabis plants.
Can You Smoke Cannabis That Has Been Treated with Colloidal Silver?
No, colloidal silver is only used on plants raised for seeding purposes, it makes the plants that it is sprayed on unsmokable.
How are Strains Crossbred?
Cannabis breeders create crossbreeds by using the pollen of one strain to pollenate seeds with another strain. The resulting seeds will have genetics from both parents. These new plants are selected by their desirable traits and then stabilized through further breeding, typically using the genetics of their parent strains.
