Many of us focus so much on the cannabis flowers and all their magical properties! Now, let’s give some attention on the right time to harvest your marijuana!
Trichome ripeness is a good measurement that provides the best moment to harvest your marijuana plant, so we need to first understand what happens to the Trichomes during the last stage of flowering. At this moment, Capitate-stalked Trichomes start to ripe and change their colour.
These Amber Trichomes contain the largest amount of cannabinoids and other compounds. It does not mean that you should harvest all the buds which have turned gold. With the help of a magnifying glass or microscope you can examine the features of trichomes. Let’s dive deep into the colour of trichomes and decide accordingly.
Three types of Trichomes
So there are actually three (possibly more) types for trichomes according to their colour on cannabis buds, secreting many different CBDs and other substances. It does not necessarily mean that more trichomes would produce a greater amount of THC. Each strain and each bud would produce its own unique mixture of CBDs and THCs, all of which interact with each other and your body to create many different ‘high’ experiences.
When a fully developed trichome bulbous head looks clear and transparent, it means the trichome has entered its early stage of ripening. Usually it occurs after 56 days of flowering. Consumption at this stage will give you citrus taste and a “high” which is much stimulating or paranoia and less sedative or calm. This happens because less terpene and cannabinoids are produced by the trichome gland at this stage. The pellucid nature of the bulbous head represents the less amount of psycho-activity hence such cannabis is not ready to harvest.
Trichome heads slowly become white or cloudy, probably the best moment to harvest most available hybrids. The milky colour represents that cells inside the trichome have partly turned into cannabinoids, terpene, flavonoides and other useful compounds. Because of the presence of several cannabinoid molecules the colour of the bulbous head might look slightly yellow. If you harvest at this stage when most of the trichomes are still milky, the effect will be pronounced cerebral and psychotropic, however the THC level would still not be at its peak.
At this stage, you can observe completely mature trichomes with fully developed bulbous. Most of the ripe trichomes turn completely yellow while some of them could still be milky with a slight golden hue. You need to wait until 70% of trichomes have turned amber to get higher concentration of CBD and THC. This is the moment when most of the growers harvest their plant. If the trichome ripeness level reaches more than 80% of the bud, the quality and concentration of CBDs and THCs would start decreasing gradually. At a later stage the bulbous head would start to shrink and burst. During this time some of the larger and lower fan leaves may begin to yellow and wilt.
However the changes in trichome color can provide a decent guide to the relative levels of CBDs and THCs in each bud. THC develops at an early stage of flowering while CBD molecules develop at a later stage. Milky stages of trichomes usually have peak amounts of THC and flavour imparting molecules called terpenes. When these terpenes turn red or amber in color, CBD production reaches its peak. At this point much of THC content already degraded to CBN adding more sedative effect to CBD. If you observe trichomes carefully you can choose the perfect moment to harvest to meet your own particular preferences.
Frequently Asked Questions
1. What weed has the most trichomes?
This solely depends on the genetics of the strain, some are genetically bred to produce large amounts of trichomes for more potent and flavorful results. If you are looking for fully powdered strains, you might want to check out White Widow, famous for her frosty, trichome covered look, or OG Kush with its extra-thick trichome structure.
2. Do male weed plants have trichomes?
Male weed plants produce trichomes for various purposes, including a defence mechanism or to facilitate pollination. However male trichomes tend to have less amount of THC and other compounds.
3. How can I get more trichomes on buds?
There are several ways to ensure larger amount of trichomes on the buds:
- Make sure you give the plant enough light throughout the growing season, as UV light is crucial for trichome production.
- Use cannabis genetics known for its increased trichome production, like those from the ‘Green rush’ in North America.
- During the last 2-3 weeks before harvest, you need to drop the humidity to 30% while keeping the temperature under 26C – this is the only proven stress method for boosting trichome growth.
4. Does rain wash away trichomes?
Yes, heavy rains and other human interference can cause damage to trichomes. If the trichomes are fully developed and ripen, such interference could cause more loss of trichomes on the bud.
5. How can I see trichomes without a magnifying glass?
The easiest method you can use to observe the trichomes without a magnifying glass is by using your phone’s camera. Make sure there’s enough light in the room, point the camera at the bud, zoom in until you see the trichomes.
6. How fast do trichomes change color?
This variable largely depends on the strain. Some transitions occur within 5 days of flowering, while others take up to 2 weeks. Make sure to check your trichomes every day.
7. Why does my weed have no trichomes?
Some strains take longer time to produce trichomes while some take less time and effort. There could be problems with trichome production if your seed is of poor quality or genetics. That is why you need to buy seeds from trusted vendors. If that doesn’t help try tips mentioned above (3).
