When To Harvest Cannabis: A Full Comprehensive Guide

When is the right time to harvest cannabis

Cannabis is a versatile plant that has been cultivated for centuries for its medicinal, recreational, and industrial uses. As the popularity of cannabis continues to grow, understanding when to harvest cannabis and the proper techniques for harvesting the plant becomes increasingly important.

The timing of the harvest can greatly impact the quality and potency of the final product, whether it is used for smoking, edibles, or topical applications. In this article, we will delve into the factors that influence the ideal harvest time for cannabis and provide tips for a successful and timely harvest.

Understanding The Trichomes

Trichomes are small, crystal-like structures on the surface of the cannabis plant that contain the majority of the plant’s cannabinoids and terpenes. These compounds are responsible for the unique effects and flavors of different strains of cannabis. As the cannabis plant matures, the trichomes go through different stages of development, including clear, cloudy, and amber.

To determine the stage of trichome development, you will need a magnifying glass or microscope. Clear trichomes indicate that the plant is not yet ready to be harvested, while cloudy trichomes suggest that the plant is approaching maturity. Amber trichomes indicate that the plant is fully mature and ready to be harvested.

However, the optimal time to harvest will depend on the desired effects and potency of the final product. For example, a plant with mostly cloudy and a few amber trichomes may be preferred for a balanced high, while a plant with mostly amber trichomes may be better for a sedative effect.

When To Harvest Cannabis?

Harvesting cannabis at the right time is crucial for the quality and potency of the final product. There are several factors that can influence when to harvest cannabis plants, including:

  • Maturity of the plants: Cannabis plants go through various stages of growth, from germination to flowering. The length of time it takes for the plants to reach maturity can vary depending on the strain and growing conditions. In general, indica strains tend to mature faster than sativa strains.
  • Trichome development: Trichomes are small, crystal-like structures that cover the surface of the cannabis plants. These structures contain the plant’s psychoactive compounds, such as THC and CBD. As the plants mature, the trichomes will change in appearance, becoming more clear and amber in color. Harvesting the plants when the trichomes are at their peak can produce a more potent and flavorful final product.
  • Plant genetics: Different strains of cannabis can have varying levels of THC and CBD, as well as different aromas and flavors. The genetic makeup of the plants can influence when to harvest cannabis, as some strains may mature faster or slower than others.
  • Environmental factors: The growing environment can also impact the ideal time to harvest cannabis. Factors such as light exposure, temperature, and humidity can all affect the maturity and trichome development of the plants.
  • Personal preference: Ultimately, the decision of when to harvest cannabis plants is a personal one and can be based on individual preferences for the desired potency and effects of the final product. Some people may prefer a more mellow and relaxing high, while others may prefer a more intense and energetic experience.

What Is The Average Time To Harvest Cannabis?

The average time to harvest cannabis can vary depending on the strain and growing conditions. In general, it takes about 8-12 weeks for cannabis plants to flower and reach maturity. Indica strains tend to mature faster than sativa strains, with some indica strains taking as little as eight weeks to flower, while sativa strains can take upwards of twelve weeks or more. 

Plants that are growing in optimal conditions tend to mature more quickly! So that’s why it’s important to monitor the development of your plants and be aware of the specific needs of your strain to ensure that they reach maturity at the optimal time for harvest.

Techniques For Harvesting Cannabis

There are several different methods for harvesting cannabis, each with their own benefits and drawbacks. Here is a closer look at the three main techniques:


This method involves cutting the plants by hand using scissors or pruning shears. It is a slower process compared to using machines, but it allows for more control and precision, making it ideal for smaller grows or for those who want to preserve as much of the plant’s structure as possible.

When hand-cutting, it is important to handle the plants gently to avoid damaging the buds or trichomes. It is also a good idea to wear gloves to protect your hands and prevent the buildup of resin.

Machine trimming

This method involves using a machine to trim the plants, which can greatly speed up the process. There are a variety of machine trimmers available on the market, ranging from manual crank models to fully automated ones.

When using a machine trimmer, it is important to follow the manufacturer’s instructions carefully to avoid damaging the plants or losing valuable trichomes. It is also a good idea to wear protective gear, such as goggles and earplugs, to protect against flying debris.


This method involves removing the fan leaves and smaller sugar leaves from the buds by hand, which can improve the appearance and quality of the final product. It is a time-consuming process but can be well worth the effort for those who want high-quality buds.

To manicure your cannabis plants, you will need a good pair of scissors or trimming shears, as well as a clean work area. Start by gently removing the larger fan leaves from the buds, taking care not to damage the trichomes.

Then, trim off any remaining sugar leaves or stem material, paying close attention to the quality of the trim. When finished, you should be left with clean, manicured buds that are ready for drying and curing.


Timing the cannabis harvest is crucial for obtaining the maximum yield and desired effects from your plants. When to harvest cannabis will depend on a variety of factors, including the strain, growing conditions, and personal preference. By understanding the different stages of trichome development and considering these factors, you can determine the best time to harvest your cannabis.

There are several techniques for harvesting cannabis, including hand-cutting, machine trimming, and manicuring, each with its own pros and cons. With careful planning and attention to detail, you can ensure a successful and rewarding harvest.
