The cultivation of cannabis is an art form that requires a deep understanding of the plant’s life cycle and the various factors that can influence its growth and development. One of the most critical stages in this cycle is the harvesting stage. The timing of the harvest, particularly the time of day when the harvest occurs, can significantly impact the quality of the final product. This article will delve into the reasons why harvesting cannabis in the morning can enhance the quality, potency, and overall appeal of your cannabis.

Terpenes and Trichomes: The Key Players

Before we delve into the reasons for morning harvesting, it’s essential to understand the role of terpenes and trichomes in cannabis cultivation. Terpenes are aromatic compounds found in cannabis that give each strain its unique scent and flavor. They also contribute to the plant’s therapeutic properties, playing a crucial role in the “entourage effect,” where the various compounds in cannabis work together to enhance the plant’s overall effects.

Trichomes, on the other hand, are tiny, resinous structures on the cannabis plant where these terpenes, along with cannabinoids like THC and CBD, are produced. The quality and quantity of these trichomes can significantly influence the potency and therapeutic value of the harvested cannabis.

The Importance of Morning Harvesting

Given the critical role of terpenes and trichomes, the timing of the harvest becomes a significant factor in cannabis cultivation. Harvesting your cannabis in the morning, just before the sun rises, can offer a multitude of benefits. Here are ten compelling reasons why you should consider this practice:

  1. Peak Terpene Levels: Terpenes are at their highest levels just before the sun comes out. By harvesting your plants at this time, you can capture these compounds at their peak, enhancing the aroma, flavor, and therapeutic properties of your cannabis.
  2. Optimal Resin Production: Cannabis plants soak up the sun during the day and produce resin and other compounds at night. The production cycle is at its peak in the morning before the light hits. By harvesting at this time, you ensure that you’re capturing the plants at their most potent stage.
  3. Efficiency: Harvesting before first light allows you to make the most of your day. You have a full day ahead of you to complete your harvest chores, leading to a more productive and efficient operation.
  4. Comfortable Temperature: The weather is generally cooler in the morning before the sun comes out. This not only makes the harvesting process more comfortable for you but also reduces the risk of heat stress on the plants, which can affect their quality.
  5. Preservation of Plant Juiciness: Harvesting in the morning, when the temperature is cooler, helps to preserve the juiciness of the plants. This is particularly important if you stop watering before harvest, as many growers do, as the buds will already be less moist.
  6. Avoiding Afternoon Drawbacks: Harvesting in the afternoon, when the sun is at its peak, can lead to drier, less juicy buds on your plants, which is not ideal. This is in addition to the lower terpene count. Harvesting in the morning helps to avoid these issues.
  7. Circadian Rhythm Alignment: Our bodies work better when we align with our circadian clock, which encourages us to wake up just before the sun and get to work. Harvesting in the morning aligns with this natural rhythm, leading to increased productivity and better overall health.
  8. Staggered Harvesting: Because the top portions of the plant mature more quickly, you may choose to harvest those parts first in the morning and give the bottom flowers another day to build potency and trichome density.
  9. Fresh Frozen Processing: If you intend to process your plants using fresh-frozen extraction techniques, harvesting several days earlier than you would otherwise, preferably in the morning, is recommended.
  10. Maximizing Overall Quality: By following all of the best practices, including morning harvesting, those small differences add up to a much larger and more potent harvest. This results in a higher quality product, whether you’re a commercial grower seeking a better return on investment or a casual consumer looking for better weed.

The Impact of Harvest Timing on Cannabis Quality

The timing of the harvest can significantly impact the quality of the final product. Harvesting too early or too late can deprive the final product of its full potential and value. Even a few days can make a difference in the potency of the final product. Because female cannabis plants spend their final days focused on resin production, cultivators must take them down during the brief window of their peak ripeness — before the medicinal compounds start to degrade.

Experienced growers offer conflicting advice for when to harvest. There are many reasons for the differences in opinion, including personal preference. Cannabis harvested earlier will have a more uplifting, cerebral effect while cannabis harvested later will be more calming. Moreover, cannabis flowers mature unevenly across an individual plant. The top flowers receive more light than the bottom flowers. Because the lower flowers get less light, they are often less potent and have fewer trichomes, the THC-rich resin glands.


In conclusion, For cultivators seeking to maximize terpene production and trichome retention, the key lies in observing the color of the trichomes and pistils, and timing the harvest accordingly. Whether you choose to hand trim or machine trim, wet trim or dry trim, the ultimate goal is to preserve the valuable trichomes that contribute to the quality and potency of the final product. By harvesting in the morning, you can ensure that you’re getting the most out of your cannabis plants, enhancing their aroma, flavor, and therapeutic properties. This practice aligns with the natural rhythm of the plant’s life cycle, ensuring that you are harvesting at the point of maximum potency and crop weight. Even a few days can make a difference in the potency of the final product. Therefore, it’s essential to pay close attention to your plants and observe the indicators, as this will dramatically increase your chances for a successful harvest.
