How Long Does It Take Before Cannabis Is Ready To Be Harvested? One of the challenging aspects of determining when to harvest cannabis is the fact that the duration of the plant’s growing phase can vary greatly by strain. In addition, grow technique and intended yield affect the duration of the plant’s growth.
In general, plants grown outdoors will take the longest to mature, although this is based on regional conditions such as the length of your natural growing season. Growing cannabis indoors allows us greater growing time flexibility. However, this often needs additional equipment and care to grow correctly.
In average, cannabis plants take between 6 and 16 weeks of growth before they are ready to be harvested. Approximately 9-12 weeks is the most typical gestational age.
How do trichomes appear when they are ready to be harvested?
CANNABIS TRICHOMES – As the buds approach full maturity, a coating of visible trichomes will cover the flowers and foliage. These trichomes are tiny resin glands on the plant’s surface that shimmer like tiny diamonds in the sun. These have likely been referred to as crystals or “Trikes.” Some cannabis strains will grow trichomes four or five weeks before to maturity, while others will develop as late as two weeks prior to maturity.
- As the buds grow, the crystals, called stalked capitate trichomes, enlarge and resemble little mushrooms as they fill with cannabinoids and terpenes.
- Under the magnification of a jeweler’s loupe, the bulbous ends of these trichomes will seem transparent while they are still forming, but will begin to become amber or milky as they mature.
This tint indicates that the cannabinoids have attained maturity and begun to breakdown. It is ready to harvest when roughly 20% of the trichomes on a bud have become amber or milky. To clarify, trichomes are not the hairs that transform from white, pink, or purple to rust or brown on the buds.
- These hairs are known as pistils, and contrary to what you may have heard, their color is not a reliable sign of a bud’s age or ripeness.
- Some cannabis plants may achieve maturity simultaneously, while others may begin to mature from the top colas down.
- Ideally, you would be able to harvest the entire plant at once; nonetheless, it is not uncommon for the top colas or exterior buds to grow more quickly.
You can harvest the ripe buds and leave the immature ones for another week or two. Frequently, the additional light offered by removing mature buds accelerates the development of the remaining buds. Without magnification, a skilled eye may be able to determine when a bud has reached maturity.
Due to the importance of doing this properly, we recommend using a jeweler’s loupe (see below for alternatives) until you gain expertise. There are several alternatives for magnifying equipment for growth, including: This is the least expensive and most low-tech technique to do the task. Unless you have exceptional eyesight, it is still tough to obtain the greatest insight into how your friends are doing.
However, the website we’ve linked to is the finest I’ve tested. Guaranteed to get the job done in a pinch! Some individuals prefer handheld magnifiers over jeweler’s loupes. They are capable of producing quality images and can generally magnify more than a jeweler’s loupe.
- However, this strength makes them somewhat less able to concentrate.
- Digital Microscope – A digital microscope is the definitive tool for identifying the time of harvest.
- It is a bit more expensive and many models require a laptop for connectivity, but it will bring you face-to-face with your trichomes.

Harvesting based on pistils – The simplest method for determining whether a bud is ready for harvesting is to examine its pistils. If the buds are beginning to form, they are all white, and around the fourth week of flowering, they will begin to change color.
How should my blossoms seem at five weeks?
Week 1: Transition of Plants from Vegetative to Flowering – The first week of the flowering cycle will find the female plants in a transitional phase. Instead of receiving 18+ hours of light every day, as they do during the vegetative cycle, the time under lights is substantially decreased.
The fact that the vegetative cycle resembles summer indicates that plants have ample time to flourish. Since a result of the reduced quantity of light the plants receive, the blooming period is accelerated, as the plants are misled into believing that winter is approaching. The plants must spend their energy on rapidly growing buds in order to be pollinated by a male plant before they perish during the winter.
Even though the plant has officially reached the ‘flowering period,’ it will not require more nutrients. A person should not abruptly switch their plant’s fertilizer regimen from vegetative to blooming the next day. Once flowering begins, it is generally advised to continue providing nutrients for at least another week.
- During week 2, the female cannabis plants will produce their first white pistils.
- These tiny, wispy white hairs grow where the large fan leaves meet the main stem.
- These white hairs will develop into colas, which are the plant’s buds.
- If a cannabis plant is male, it will produce pollen sacs rather than white hairs.
Now is the time to “sex” your plants, which means to separate the men and females. It is crucial to sex the plants during this time period because male plants might pollinate the female plants, leading them to produce seeds in their blossoms. This is something a grower would never want, as the quality of the ultimate product would suffer significantly.
Increasing blooming nutrients is often necessary for plants to attain their optimum yield potential around week 2, when they begin to blossom and beginning the first symptoms of bud development. The cannabis plants will be far larger than they were three weeks ago, with the size of certain strains tripling.
The stretching of the plant will progressively slow down and finally cease, allowing the plant to spend its energy on flower production before “winter” ends their lives. The first three weeks are hence known as the “stretch phase.” While the plants are working hard to acquire bulk and height in preparation for ‘winter,’ they will also produce a large number of new leaves, primarily at the top of the major colas.
- Plants do this in order to become more robust and able to support the next large buds.
- Where white hairs had existed, there should now be the earliest symptoms of the development of true buds.
- Due to a lack of resin glands and trichomes on the plant at this stage, the odor will not be particularly powerful.
This phase, in which female plants begin to devote more energy to flower development, is crucial. It is essential that they receive the proper nutrients and doses. If a plant’s leaves are yellowing or falling off, it may require additional nutrients. If a plant is overfed, resulting in “nutrient burn,” discoloration may appear at the leaf tips.
At this point in the blooming phase, the cannabis plant has likely ceased growing. The plants are currently devoting all of their energy to bud development, expecting to be pollinated by a male in order to produce seeds that will germinate in the spring. If you have properly sexed your plants, the bud sites will continue to increase in size.
Even though there are still white hairs protruding from the buds, the buds get larger with each passing day, and as the buds expand, the plants manufacture more trichomes. This makes the odor far more pungent. After the rise in bud size, the plants may require structural support, as they may begin to lean or topple owing to the added weight.
All of the plant’s buds have gotten denser. There may be new buds in new locations, such as near the cola. Cannabis plants continue to gain weight daily. This is a positive indicator that the plant is in full bloom. At this stage, the odor will be quite strong. Some of the plant’s white pistil hairs may become amber or brownish in hue.
Meanwhile, the plant’s trichomes may also be growing opaque. Dark hairs and milky-white trichomes are positive indicators that the plants are nearing harvest. Different cannabis plants exist. Some plants take longer time to bloom than others. Although several types are ready for harvest in these last three weeks, the majority are not ripe until week 8.
- Flushing is vital to a successful crop.
- Flushing is the process of applying pH-balanced, pH-neutral water to the soil to eliminate any remaining nutrients after a plant has stopped receiving food.
- When nutrients are taken from the soil, the plant is forced to consume the remaining nutrients inside itself.
Similar to how people store fat for energy during times of food scarcity, the plant will utilize its stores. Ultimately, a cultivator wishes for the plant to have no remaining nutrients, or “fat,” when it is harvested. Having no nutrients is essential, since they might contaminate the buds after harvest and provide a foul, chemical flavor when smoked.
To determine when a plant is ready to be harvested, its trichomes are examined using a microscope or jeweler’s loupes. If the trichomes go from transparent to milky white, it may be ready to harvest. If several trichomes are still visible, it is too early to harvest. When the THC concentration of the buds has reached its peak, the trichomes will be opaque and amber in color.
