Harvesting Seeds from Cannabis Plants

As a cannabis grower, the ultimate goal is to harvest buds with high THC levels, impressive aroma, and flavor. However, another vital aspect of cultivating cannabis is to harvest seeds to ensure the survival of the species. Harvesting seeds from cannabis plants may seem like a complicated process, but it is relatively easy if you follow the right steps. Knowing when to harvest and how to go about it is essential to ensure your seeds’ quality and viability. In this article, we’ll take a closer look at harvesting seeds from cannabis plants and everything you need to know to ensure a successful seed harvest.

When to Harvest


When To Harvest
As a cannabis grower, one of the most crucial decisions you’ll make is when to harvest your plants. It’s a perplexing process, and knowing exactly when to cut down your cannabis can make a huge difference in the quality and potency of your final product. There are several factors to consider, such as observation, trichome maturity, and weather conditions. Let’s dive into each of these aspects and explore how they can help you determine the best time to harvest your cannabis plants.


One of the primary ways to know when to harvest cannabis plants and their seeds is through observation. This requires keen attention to detail and a willingness to inspect the plants regularly. Here are some things to look out for in your observations:

Observation Area What to Look For
The Pistils These are the hair-like structures on the buds of the plant. When they start to change color from white to brown or amber, this can be an indication of maturation.
The Leaves Yellowing leaves can also be a sign of maturation. If the larger leaves on the plant start to yellow and then fall off, this can be a sign that the plant is getting ready to harvest. However, if the smaller leaves near the buds are turning yellow, this could be a sign that the plant is stressed or diseased.
The Buds Aside from observing the pistils, buds can also be analyzed by observing their density and overall size. When the buds start to get bigger and denser, this can be a sign of maturation. Additionally, when the resin on the buds starts to dry and become sticky, this can also be a sign of readiness for harvest.

Observing these areas of the plant can help determine when the cannabis plant is ready to be harvested for seeds. Keep in mind that observation should be done regularly and consistently to ensure the best results.

Trichome Maturity

When determining the ideal time to harvest cannabis seeds, one of the most important factors to consider is the maturity of the trichomes. These tiny, hair-like structures on the plant’s flowers are responsible for producing the cannabinoids and terpenes that give the plant its unique effects and aroma.

Here are some key indicators to look for to determine when the trichomes are mature enough for harvesting:

  • Color: In the early stages of growth, trichomes are typically clear or translucent. However, as they mature, they begin to develop an amber or cloudy appearance. This change in color is a clear indication that the plant is nearing its peak potency.
  • Size: Mature trichomes will typically appear larger than immature ones, especially when viewed under a microscope. This is another signal that the plant is ready for harvesting.
  • Density: As the plant matures, the trichomes will also become more densely packed together. This creates a more noticeable layer of resin on the plant’s flowers.

It’s important to note that different strains of cannabis may have different ideal trichome maturation levels, so it’s important to do your research on your specific strain. Additionally, harvesting too early or too late can have a significant impact on the potency and overall quality of your seeds. To ensure the best results, it’s recommended to use a combination of visual observation and microscopic analysis to determine the ideal time for harvesting.



Weather plays an important role in determining when to harvest cannabis seeds. Ideal weather conditions during the harvest period can help ensure high-quality seeds with high germination rates. On the other hand, adverse weather conditions can lower the quality and reduce the quantity of seeds produced.

In general, it is best to harvest cannabis seeds during a dry spell or when the weather is sunny and warm. This is because high humidity levels and dampness can cause mold and mildew, which can ruin the seeds. Additionally, excessive rain or strong winds can knock the seeds off the plant, leading to loss of yield.

To keep track of the weather conditions during the harvest period, it is a good idea to use a weather app or check the weather forecast regularly. It is also important to choose a good location for harvesting, where the plants are protected from excessive rain or strong winds.

Here’s a table summarizing the ideal weather conditions for harvesting cannabis seeds:

Weather Condition Description
Dry Spell Ideal time to harvest seeds
Sunny and Warm Helps prevent mold and mildew
Low Humidity Reduces risk of mold and mildew
No Rain Helps prevent loss of yield
No Strong Winds Helps prevent loss of yield

By keeping an eye on the weather and choosing the right time to harvest, you can ensure that your cannabis seeds are of the highest quality and have the best chance of producing healthy and strong plants.
