Photoperiod describes the amount of time a plant receives each day. In cannabis cultivation, it describes a type of cannabis plant that reacts to light cycles with distinct changes in growth. Does that mean that photoperiod cannabis strains are a subtype similar to autoflowers? No.
Photoperiod seeds and regular seeds describe the same type of cannabis, which is the type that responds to changes in the light cycle. We also use the word photoperiod cannabis seeds to differentiate them from autoflowering and feminized seeds.
Autoflower vs. photoperiod seeds
You cannot compare autoflower vs. photoperiod on their appearance alone. The difference begins once you grow them, starting with their size. A photoperiod plant is generally much taller than an autoflower which is the make-or-break factor for some growers when choosing a strain.

The other two main differences between photos and autos are their yield and how they respond to light cycle changes. It’s well-known that autoflowering cannabis strains produce plants that yield less than their photoperiod counterpart, but what’s equally known is how they don’t need a change in light schedule to flower– hence the name.
Other questions that often come up:
Are photoperiods easier to grow?
Photoperiod cannabis plants are said to be slightly more difficult to grow than autoflowering cannabis. This is because any photoperiod cannabis strain needs a change in its light cycle to start flowering, unlike autoflowers which switch to their flowering period automatically.
Do autoflowers grow faster than photoperiod seeds?
Autoflowering seeds grow much faster than photoperiod ones, thanks to their ruderalis genetics. Because cannabis ruderalis grew in the harsh conditions of southern Siberia with poor soil conditions and short growing seasons, it needed to adapt. The result is a strain of cannabis known for producing an early-maturing, autoflowering crop.
Do photoperiods yield more?
Generally speaking, photoperiod cannabis plants produce far more smokable flowers than autoflowers because of how much larger they grow. A recent 2023 study also showed that optimizing light schedules for photoperiod strains resulted in higher yield and greater cannabinoid content.
Are photoperiod seeds feminized?
Not necessarily. While you can find regular photoperiod seeds that are also feminized, it’s not always the case. Photoperiod seeds cover regular cannabis seeds as well, which produce female and male plants.

How do you grow photoperiod seeds?
When growing photoperiod cannabis seeds, you must be certain about three key factors. These are the length of your plant’s veg time, the light schedule you use during vegging, and the light schedule you use for flowering. These three factors will determine the yield and cannabinoid content of your marijuana.
Typically cannabis needs a vegetative period of at least 4-6 weeks to grow and develop. This ensures the highest possible yield. In terms of lighting, the general agreement is giving marijuana 18 hours of light and 6 hours of darkness during vegging and a static 12 hours of light and darkness during flowering.
Other factors will affect your yield and the time it takes to grow your marijuana, such as the type of strain you choose (sativa vs. indica), your setup (indoors or outdoors), and the growing technique you apply.
Check out our weed marijuana grow bible for more information on how you can control the growth of your marijuana plants.
How long do photoperiods take from seed to harvest?
Indoors, photoperiods can take between 15 and 16 weeks from seed to harvest. Outdoors, photoperiods can take between 20 and 21 weeks from seed to harvest.
Again, these numbers are predicated on the choices you make as a grower. Do you want to harvest sooner? Or do you want to give the plant all the time she needs? You’re in control and there are many different options to utilize that control. Like, when you’re growing outside and you want your plants to flower earlier, you can implement a ‘light deprivation technique’ to achieve that.
How early can you flower a photoperiod?
The earliest you can initiate flowering is after two weeks of vegging photoperiod plants. But is it the best time to switch? It depends on your preference.
A 2022 study confirmed that the yield of sativa strains is tied to the number of weeks you give them to veg. A shorter vegetative period is preferable for maximizing yield, but the trade-off is decreased potency. To increase THC and CBD levels, you must give your plants longer veg but at the cost of decreased yield.

That choice between greater yield but less potent bud and more potent bud for less yield is a personal preference– a choice you can only have as a home grower.
Does photoperiod affect germination?
No studies show that the photoperiod trait in cannabis affects the germination of its seeds. This is especially evident when comparing autoflowers and photoperiod seeds; they both take the same number of days to germinate (1-3 days).
But, a 2017 study showed the relationship between photoperiodism and seed germination. In it, Thale cress produced seeds with higher germination percentages by experiencing short days before reproduction (vegging) and long days during reproduction (flowering).
It’s unclear if this translates to marijuana cultivation since cannabis would require vegging under 12 hours of light and darkness and flowering at 18 hours of light and 6 hours of darkness.
How much light do photoperiods need?
Although the general agreement for the amount of daily light you should give your photoperiods during vegging is 18 hours and 12 hours during flowering, science may suggest otherwise.
A recent study said giving your cannabis a static 12 hours of light and darkness isn’t optimal if you’re looking to maximize the fresh weight of your yield and the cannabinoid content in your flowers.
The recommended practice is to give your flowering cannabis 14 hours of light at the start before reducing it to 12 or 10 hours. Doing so results in increased yield and potency.
This is especially true with the following strains:
Buying photoperiod seeds
When purchasing cannabis seeds, knowing what you want is important. If you want to be a breeder or produce seeds, use photoperiod cannabis seeds. They’re also good if you want to breed strains, create new phenotypes or grow clones.
But if you’re a new grower who just wants to grow their own weed, we recommend starting with feminized or autoflower seeds. They’re much easier to care for, and in particular, feminized seeds are more convenient since you don’t need to worry about accidentally growing a male plant that would pollinate your females.
Lastly, you must source your seeds from the right seed bank. You can trust ILGM.com for high-quality cannabis seeds. While there, don’t forget to download Robert’s Grow Bible to make growing marijuana fun and easy to learn.

Indica vs Sativa
Who would have thought that in marijuana there are different types of plants with completely different effects and benefits? The origin, the climate, the effects, and the physical characteristics are crucial in order, to differentiate the type of plant that you are going to use either in the clinical, pharmaceutical, or recreational field, as well as to know between Cannabis Sativa and Cannabis Indica in order, to be able to make the best selection of seeds according to your needs.
Marijuana is a well-known plant for its mind and body effects and it’s split into two main types: Sativa and Indica. Even though they come from the same family and have similar ingredients, they’re different in how they look and what they do when you use them. Let’s break it down simply:
What the plants look like:
Indica: This plant is short and looks like a bush with wide leaves. It grows well in cooler and mountainous areas.
Sativa: This one is tall and thin, with skinny, pointed leaves, kind of like a young pine tree. It likes hot and humid places.
How they make you feel:
Indica: It chills you out and can make you sleepy, like when you’re getting cozy in bed after a long day.
Sativa: It energizes you and wakes up your mind, great for when you need to do things that require imagination or when you’re hanging out with friends.
To put it simply: if you want to relax, go for Indica. If you want to be more alert and active, go for sativa. We’ll explain more about this soon so you can better understand how each one affects people differently.
The two subspecies of marijuana represent different adaptations to different climates. Sativa originates from the jungles of equatorial regions such as Thailand, Cambodia, Jamaica, Colombia, and Mexico, places that enjoy long hours of sunshine and constant light throughout the year. The Indica variety, on the other hand, comes from the Hindu Kush region, a vast mountain range of more than 800 kilometers that stretches from Afghanistan to China and is characterized by a very cold climate.
Climatic and physical characteristics
Cannabis Sativa is known for its ability to adapt to the heat of tropical climates, being resistant to low temperatures and showing an effective ability to prevent the growth of fungi commonly associated with humidity. Indicas, on the other hand, originate from mountainous climates, which enables them to withstand climatic challenges such as wind, rain, and frost.
Morphology and appearance:
Morphology of Cannabis Sativa
Cannabis Sativa plants, are distinguished by their unique morphology and appearance, which tend to be taller and more slender, with long, thin leaves, differentiating them from other marijuana species such as Indica and Ruderalis. The following points highlight the main morphological and appearance characteristics of Sativa:
- Height and Structure: Cannabis sativa plants are typically tall and slender, with some varieties reaching heights of up to 20 feet (about 6 meters) under optimal conditions. They have a more open structure compared to the bushier Cannabis indica, allowing for greater light penetration throughout the plant.
- Leaves: The leaves of Cannabis sativa are characteristically long and narrow with a light green color. They possess serrated edges and are composed of slender leaflets that are spread far apart. The number of leaflets can vary, usually between 5 to 13 per leaf.
- Branching: Sativa plants have less dense branching compared to their indica counterparts, with branches extending outward and upward, giving the plant an airy appearance. This less compact structure is beneficial for air circulation and can help in reducing the risk of mold and fungal diseases in humid environments.
- Flowers (Buds): The flowers of Cannabis sativa are elongated and less dense than those of indica plants. They tend to be more “fluffy” or airy and can appear on the plant as spaced, apart clusters. The flowering period for sativa strains is generally longer, often taking between 10 to 16 weeks to fully mature.
- Trichomes: While both sativa and indica plants produce trichomes (the resinous glands containing cannabinoids), the concentration and distribution can vary. Sativa plants typically have a high concentration of trichomes on the flowers and surrounding foliage, contributing to their potent therapeutic and psychoactive properties.
- Root System: Cannabis sativa plants develop a deep taproot system, which enables them to access water from deeper soil layers. This characteristic is beneficial for plants growing in arid conditions, allowing them to thrive where other plants might not.
- Growth Pattern and Maturation: Sativa strains usually have a longer vegetative growth phase, which contributes to their tall stature. Their extended flowering time requires patience but can result in high yields of marijuana flowers.
Cannabis sativa strains are often associated with a cerebral, uplifting high, attributed to their higher concentration of THC in comparison to CBD. This makes them particularly popular for daytime use. The distinct morphology and appearance of sativa not only contribute to its cultivation requirements but also influence its effects and applications, making it a fav
Morphology of Cannabis Indica
Cannabis Indica plants have distinctive morphological traits, shorter and more compact appearance, with wider and denser leaves, traits that differentiate from Sativa and Ruderalis. The main characteristics of Indica are described below:
- Height and Structure: Cannabis indica plants are generally shorter and bushier than their sativa counterparts, typically reaching heights of 2 to 4 feet (about 0.6 to 1.2 meters). They have a compact, dense structure, which makes them well-suited for indoor cultivation.
- Leaves: The leaves of Cannabis indica are broad and dark green, with fewer but wider leaflets compared to sativa plants. Indica leaves often have between 7 to 9 leaflets, which are closer together, giving the leaf a fuller appearance.
- Branching: Indica plants have dense branching, with closer internodal spaces. This compact growth habit results in a bushy appearance and contributes to their ability to produce more buds in a smaller space.
- Flowers (Buds): The buds of Cannabis indica plants are typically dense, thick, and bulky, clustering around the plant’s nodes. Due to the plant’s compact nature, these buds are often heavier and more resinous than those of sativa strains, leading to higher yields per square foot in controlled environments.
- Trichomes: Cannabis indica plants are known for their abundant trichome production, which covers the buds and surrounding foliage in a thick layer of crystalline resin. This resin is rich in cannabinoids like THC and CBD, making indica strains highly potent.
- Root System: Indica plants have a more spread-out root system compared to the deep taproot of sativa plants. This characteristic makes them more adaptable to various growing mediums and efficient in nutrient uptake from the soil.
- Growth Pattern and Maturation: Cannabis indica strains have a shorter vegetative growth phase and a faster flowering cycle than sativa strains, often maturing in 6 to 8 weeks. This quick turnaround makes them attractive to cultivators looking for a fast crop.
- Effects: Indica strains are traditionally associated with a sedative, body-centric effect, often referred to as a “body high.” This makes them popular for evening use, providing relaxation and aiding in sleep.
The morphology and appearance of Cannabis indica are not just significant for identification; they also have practical implications for cultivation and use. The compact, dense growth of indica plants makes them particularly suited for indoor or space-constrained environments. Their potent, resinous buds are favored for their strong therapeutic effects, offering relief from pain, anxiety, insomnia, and more.
Chemical and Psychoactive Composition
Both subspecies contain a variety of chemical compounds, but the proportions of these compounds can vary.
Cannabis Sativa: Sativas tend to have higher levels of tetrahydrocannabinol (THC), the compound responsible for the psychoactive effects. They may also contain significant amounts of cannabidiol (CBD), which has health properties, but in lower proportions than THC.
Cannabis Indica: Indicas generally have slightly lower THC levels than Sativas, but can still be potent. They tend to have a more balanced ratio of THC and CBD, which can result in a more relaxing and sedative effect.
When it comes to psychoactive effects, it is important to remember that although both Sativa and Indica contain THC, the effects and reactions vary greatly depending on the type of plant.
So which strain is right for me? Amsterdam Marijuana Seeds can tell you:
Sativa is known for its properties that induce a state of euphoria and greater sociability compared to the Indica variety. This sub-species enhances perception, intensifying the appreciation of colors and sounds while stimulating creativity and thinking. Sativa is used to relieve stress, anxiety, depression, nausea, migraines, and as an appetite stimulant, among other wellness benefits.
On the other hand, Indica, known for its relaxing and sedative properties, is highly effective in the treatment of insomnia and a variety of conditions. It is widely used to alleviate neuromuscular disorders such as tremors and, spasms, and to combat chronic pain. It is also a valuable option for reducing anxiety and stress and stimulating appetite in patients who need it.
Alternative uses
Cannabis Sativa: Sativas are often used to treat depression, anxiety and to improve mood. They can also be useful in treating attention deficit disorder and stimulating appetite.
Cannabis Indica: Indicas are preferred for the treatment of chronic pain, insomnia, anxiety and to relax tense muscles. They are also commonly used to treat gastrointestinal disorders.
It is important to note that due to hybridisation and genetic variability of marijuana strains, classification as sativa or indica is not always accurate. In addition, individual experience with these subspecies may vary between individuals and specific strains.
Sativa and Indica are two subspecies with marked differences in morphology, chemical composition, psychoactive effects, and alternative uses. The choice between one or the other depends on the personal preferences and therapeutic needs of each individual.

CBD Seeds
CBD marijuana seeds share characteristics with feminized, regular, or autoflowering varieties, but are distinguished by their higher CBD content compared to conventional varieties. Additionally, in many cases, the aim is to minimize the THC level so that they can be used for medicinal purposes.
However, these seeds never contain the adequate concentration of THC for use in legal CBD product production, which currently must be below 0.2%. For this purpose, hemp seeds are used. Despite this, CBD marijuana seed varieties still offer more relaxing and stress-relieving effects than other varieties.
Hemp Seeds
Unlike CBD seeds, hemp seeds always contain THC levels below 0.2%, ensuring a predominance of CBD. Also known as industrial hemp, this variety is used for CBD extraction and the production of therapeutic products. However, the CBD levels obtained from hemp never reach those achieved with CBD seeds.
Hemp seeds are not only used for obtaining cannabidiol but also for extracting strong fibers used in various industries, such as textile, paper, insulation, rope manufacturing, fuel, paints, cosmetics, among others. Additionally, hemp seeds are edible and can be consumed as oil, whole, raw, toasted, or ground into flour.
Fast Version Seeds
Like CBD marijuana seeds, Fast Version seeds have similar characteristics to regular or feminized varieties, but their life cycle is shorter than usual, allowing for harvesting before the first October frosts.
Indeed, many of these types of seeds can be combined. Sativa, indica, hybrid, or ruderalis varieties can be presented in feminized, regular, autoflowering, or Fast Version forms. Hemp seeds, on the other hand, belong to the sativa group.

The Mystique Of Purple Weed: Colors, Potency, And Flavor
Published

Undeniably, purple buds are awesome. Purple cannabis strains have an exotic appearance and often bear cool names like Blue Dream XTRM or Purple Power XTRM. But does their deep purple pigment indicate potency or alter the taste compared to regular green weed? Read on to discover the answers.
Purple or Another Shade of Color
Firstly, let’s explain why certain marijuana strains turn purple or display other colors. The reason lies in their genetic ability to produce anthocyanins. Anthocyanins are a family of flavonoids that generate pigments such as blue, purple, or red. Various fruits and vegetables like eggplants, blueberries, purple grapes, and red cabbage naturally contain anthocyanins. Some marijuana strains possess higher levels of anthocyanins due to their genetic makeup. Since anthocyanins are potent pigment compounds, only a small amount of these flavonoids is required for the plant to exhibit bold colors.
Anthocyanins are found in the vacuoles of cells within the plant’s leaves, flowers, and fruits. These flavonoids can also migrate to the marijuana trichome stalk and even reside inside the trichome head, creating an intriguing visual effect. The presence of anthocyanins in the trichomes adds to the overall appeal of purple cannabis strains.
It is important to note that the color of cannabis plants is not solely limited to purple. Some strains may exhibit shades of blue or red. The final coloration depends on several factors, including genetic predisposition, environmental conditions, and the pH level.
The Role of Genetics and Pigments
The genetic makeup of a marijuana strain plays a significant role in determining the presence and concentration of anthocyanins. Some strains are bred specifically to enhance the expression of these pigments, resulting in vibrant purple hues.
Flavonoids, including anthocyanins, serve multiple purposes in plants. They act as natural sunscreens, protecting photosynthetic tissues from excessive light and UV radiation. In cannabis, anthocyanins help shield the leaves from high light intensities, reducing stress on the plant. These pigments also contribute to antioxidant properties, offering additional protection against environmental stressors.
The production of anthocyanins is influenced by various environmental factors, such as temperature, light exposure, and nutrient availability. Cooler temperatures, particularly during the late stages of flowering, can stimulate anthocyanin production and intensify the coloration of cannabis plants.
The pH level of the plant’s environment also plays a crucial role in determining the color. Anthocyanins respond to changes in pH, exhibiting different shades depending on whether the environment is acidic, neutral, or alkaline. In an acidic environment, the plant tends to display red or pink colors. Neutral environments result in purple hues, while higher pH levels lead to blue shades. Yellow colorization occurs in alkaline environments. Anthocyanin pigments thrive best in an acidic environment, which is why many purple cannabis strains exhibit their vibrant colors under slightly acidic conditions.
Taste and Aroma of Purple Weed
Contrary to popular belief, the taste and aroma of purple weed are primarily determined by the strain rather than the color. While some people expect purple weed to have a grape-like flavor, the reality is that the flavor profile varies greatly among different strains.
Each strain possesses its own unique combination of terpenes, aromatic compounds that contribute to the taste and smell of cannabis. The terpene profile of a strain plays a significant role in determining its flavor characteristics. For example, some purple strains may have fruity or berry-like flavors, while others might exhibit earthy or spicy undertones.
It’s important to note that the taste and aroma of cannabis are subjective experiences that can vary from person to person. What one individual finds appealing, another may not enjoy as much. Therefore, it’s recommended to explore different strains and experiment to find the flavors that suit your palate.
Perception of Potency of Purple Weed
Purple cannabis strains have gained a reputation for being potent and highly desirable among consumers. However, it’s essential to clarify that the color of the bud itself does not directly correlate with its potency. The level of tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis, is not inherently influenced by the color of the buds.
The potency of a cannabis strain depends on various factors, including specific genetics, cultivation techniques, harvesting, and curing processes. While some purple strains may indeed be potent, it’s crucial to evaluate the overall cannabinoid and terpene profile of the strain to determine its effects and potency accurately.
Additionally, factors such as trichome density, resin production, and overall cannabinoid content contribute to the potency and quality of the cannabis. These characteristics can vary among different strains, regardless of their color.
Rarity and Market Value of Purple Weed
Purple cannabis strains tend to be rarer compared to their green counterparts. The distinctive coloration and unique visual appeal make them sought after by cannabis enthusiasts and collectors. As a result, the market value of purple buds may be higher due to their relative scarcity and aesthetic appeal.
Furthermore, the cultivation process for purple strains can be more challenging and time-consuming. Growers often need to carefully manage environmental conditions, including temperature, light exposure, and nutrient availability, to encourage the expression of anthocyanins. These additional efforts contribute to the higher cost of producing purple cannabis strains, which may be reflected in their price.
The Influence of Environmental Factors
Environmental factors play a significant role in determining the color expression of cannabis plants. Apart from genetics, the following factors can influence the coloration of the buds:
Temperature:
Temperature fluctuations can impact the coloration of cannabis plants. A drop in temperature during the flowering phase can stimulate anthocyanin production and intensify the purple, blue, or red hues. Conversely, higher temperatures may reduce the expression of anthocyanins, resulting in less vibrant colors.
Light Exposure:
The intensity and duration of light exposure can influence color development in cannabis plants. Certain strains may require specific light conditions to maximize the expression of anthocyanins. Adequate exposure to ultraviolet (UV) light during specific stages of growth can enhance the coloration of the buds.
Nutrient Availability:
The availability and balance of essential nutrients can affect the overall health and coloration of cannabis plants. Deficiencies or excesses in certain nutrients can lead to color variations and impact the intensity of pigmentation. Providing optimal nutrient levels, particularly micronutrients, can help promote vibrant color development.
Appreciating the Beauty of Purple Cannabis
Whether you’re a cannabis enthusiast or a casual consumer, purple buds offer a visually striking and captivating experience. The rich hues and vibrant colors add a touch of uniqueness to the cannabis landscape.
It’s worth noting that while the color of the buds may not directly affect their potency or taste, the visual appeal and novelty factor associated with purple strains can enhance the overall enjoyment of the cannabis experience. From aesthetic pleasure to the diverse range of flavors and aromas, exploring different purple strains allows for a deeper appreciation of the plant’s intricacies.
