How and when to harvest based on trichomes?

Harvesting marijuana plants is a crucial moment that will determine the final quality of your product. An essential factor to take into account is the state of the trichomes, those small crystals that cover the buds and sugar leaves. Understanding how and when to harvest based on the trichomes is key to achieving the desired effects and maximizing the potential of your plants, which is why today, from Grow Industry, an online store for growing products, we are telling you everything you need to know about it.

When to harvest your marijuana plants?

Determining the right time to harvest is crucial to getting the best effects and potency from your plants. Most growers agree that the optimal time to harvest depends largely on the state of the trichomes. Trichomes are small glandular appendages on the surface of buds that produce and store resin and cannabinoids such as THC and CBD.

Watching trichomes closely allows you to identify when the plant has reached its full potential. As trichomes mature, they change color, going from clear to milky and finally to amber. This color change indicates different levels of maturity and therefore different effect profiles when consuming the final product. Therefore, regular observation of trichomes is an essential practice for any serious grower.

In addition to trichomes, other indicators such as the color of the pistils and the general condition of the plant can also help you decide when is the right time to harvest. Harvesting too early or too late can negatively affect the cannabinoid and terpene profile, which in turn influences the taste, aroma, and effect of marijuana. Therefore, keep a regular check on all these aspects to ensure harvesting at the optimal point.

The importance of harvest time depending on the desired effect

The time you decide to harvest your marijuana plants can significantly influence the effects you experience when consuming it. This is because trichomes, as they mature, alter the chemical composition of the resin they contain, thus affecting the levels of THC, CBD, and other cannabinoids .

Transparent trichomes

When trichomes are in their clear phase, it means that the plant has not yet reached full maturity . Harvesting at this stage generally produces lighter, more stimulating effects, due to the fact that THC levels have not reached their maximum. This is an option for those looking for a softer, more cerebral effect , ideal for daytime use and for those who prefer to avoid overly intense sensations.

At this stage, the resin is less dense, which also translates into a lower yield in terms of quantity and quality of the harvest. However, some growers prefer this harvest point for certain strains that produce clear, energizing effects . It is important to note that the overall potency of the final product will be lower compared to a harvest at a more advanced stage.

Milky trichomes

When the trichomes turn milky or whitish, it is a sign that the plant is at its optimal point of maturity. This is the ideal time to harvest if you want to obtain a product with high levels of THC and potent psychoactive effects. Milky trichomes indicate that cannabinoids are at their peak concentration, offering a euphoric and cerebral effect .

This harvest point is especially popular among growers looking to maximize the psychoactive effects of their marijuana. Additionally, strains with an energizing and creative effects profile are often harvested at this stage to capture the best balance between potency and mental clarity. Resin quality is high, which also translates into a better flavor and aroma experience.

Amber Trichomes

Trichomes that have turned from milky to an amber hue indicate that the plant has begun to break down THC into CBN, a cannabinoid that causes more sedative and relaxing effects . Harvesting at this stage is ideal if you prefer a deep body high, perfect for relaxation, pain relief, and for those looking for a more narcotic effect .

The color change to amber also indicates that the plant is reaching the end of its life cycle, and the quality of the resin can begin to decline if left too long. However, for medicinal users looking for potent relief from symptoms such as insomnia or chronic pain, this is the optimal time to harvest. The terpene profile can also change at this stage, offering a more complex and earthy flavor.

Mixed trichomes

When you see a mix of milky and amber trichomes, it means the plant is at a midpoint between peak THC and the start of CBN degradation. Harvesting at this time can provide a balance of cerebral and body effects , ideal for those looking for the best of both worlds: a cerebral high followed by deep relaxation .

This phase is ideal for those who want to enjoy a well-rounded experience, with an energetic start that fades into a more calming effect. It is a versatile harvest point, suitable for both recreational and medicinal use, as it combines potency with a long-lasting relaxing effect . The mix of milky and amber trichomes can also offer a richer and more complex flavour and aroma profile.

What is the cutting point according to the trichomes?

Determining the exact cut-off point for harvesting based on trichomes is an art that requires experience and careful observation. The balance between milky and amber trichomes is often the benchmark for many experienced growers. This balance provides a versatile effect, combining the benefits of THC at its peak and the relaxing effects of CBN that begins to form.

If you're looking for a more cerebral and uplifting effect, opt to harvest when most of the trichomes are milky . This will maximize the THC content and give you a final product with an energetic and euphoric high. It's ideal for strains that are enjoyed during the day, where mental clarity and motivation are key.

On the other hand, if you prefer a more physical and relaxing effect, wait until a higher proportion of trichomes have turned amber. This approach is perfect for evenings or for situations where you are looking for deep relief from stress or pain. The effect will be more sedating, making the experience more suitable for relaxing and unwinding.

How to inspect trichomes?

Inspecting trichomes requires proper technique and simple tools, such as a magnifying glass or pocket microscope. Regular observation of trichomes will allow you to make informed decisions about harvesting time, ensuring you cut your plants at the exact point you want.

Ideally, you should start observing trichomes a few weeks before your estimated harvest date. Do this at different points on the plant , as trichomes on the upper, more sun-exposed parts can mature faster than those on the lower parts. This will give you a more complete picture of the overall maturity of the plant.
