Auto Purple

Auto Purple: Purple Genetics in an Autoflowering Format

Auto Purple by Pyramid Seeds stands out primarily because of the colour of its flowers - rich violet, purple and, in places, almost plum-like shades make this line visually recognizable even before its aromatic profile is explored. The manufacturer classifies the strain as a balanced hybrid with an approximate ratio of 50% sativa and 50% indica. The seeds are presented in a feminized autoflowering format. The stated THC concentration is 18-20%, while CBD is below 1%. 

Origin and Genetic Character

Auto Purple is based on the European Purple Fem line from Pyramid Seeds, adapted to an autoflowering development pattern. The breeding objective was not only to change the flowering mechanism, but also to preserve the most noticeable traits of the original Purple - its characteristic pigmentation, sweet berry aroma and balanced combination of indica and sativa characteristics.

In the Pyramid Seeds catalogue, Auto Purple belongs to the European collection and is identified by the manufacturer as one of the popular representatives of purple genetics. Such lines are valued primarily for their pronounced anthocyanin pigmentation. Anthocyanins are responsible for the purple and violet shades of plant tissues, although the degree to which these colours appear is determined not by the strain name alone, but also by the heredity of a particular phenotype and environmental conditions.

The 50/50 genetic balance clearly distinguishes Auto Purple from strains with a strong tendency toward either indica or sativa. Its morphology and reported character of effects sit approximately in the middle: the line is not positioned as exclusively heavy indica genetics, but neither does it belong to strongly stimulating sativas.

Indoors, plants can reach approximately 40-140 cm, while for outdoor environments the manufacturer specifies a height starting from 60 cm. The complete cycle is approximately 65 days from germination, while under certain LED conditions a figure of around 58 days is given. These numbers are breeder reference specifications rather than a rigid biological schedule for every individual plant.

Unusual Colouration of Auto Purple

The main visual feature of Auto Purple is its ability to develop intense violet shades. The colouration may cover not only individual sections of the flowers but also adjacent leaves, creating transitions from dark green to purple, lilac and deep violet.

The reason for this colour is associated with the presence of anthocyanin pigments. Their quantity and visibility are genetically determined, although the external environment can also influence the intensity of the colouration. For this reason, two plants from the same line do not necessarily look exactly alike: one phenotype may display an almost uniform purple tone, while another may show only isolated violet areas.

Aroma Profile of Auto Purple

The aroma of Auto Purple is built around a sweet berry-fruit direction. While Auto Northern Lights leans toward earth, wood and pine resin, the composition here is noticeably softer and juicier. The manufacturer describes it in terms of forest berries, ripe fruit and sweet nuances.

The first impression is usually a dense berry layer. It may resemble a mixture of dark forest berries without any one specific fruit clearly dominating. This is followed by a riper fruit sweetness, while light earthy and spicy nuances remain in the background.

This aromatic profile does not feel one-dimensional. Berry sweetness sets the main direction, but the terpenes add drier, peppery and floral details. As a result, the scent does not turn into a straightforward fruit note.

Terpenes: Myrcene, Caryophyllene and Linalool

The manufacturer primarily associates the terpene profile of Auto Purple with myrcene, caryophyllene and linalool. This combination helps explain the characteristic transition from fruity berry sweetness to spicy and softer floral nuances.

Myrcene forms the lower part of the aromatic profile. It is generally described as earthy, slightly musky, herbal and fruity at the same time. In Auto Purple, it works well with the overall berry direction and makes the aroma feel less sharp.

Caryophyllene adds a dry peppery quality and warm spice. Its role is particularly noticeable in contrast with the sweet notes: without this spicy component, the aroma could come across as excessively candy-like and monotonous.

Linalool occupies the softer part of the composition. Its aroma is usually associated with floral, slightly sweet and herbal notes. Against the background of myrcene and caryophyllene, it works delicately, adding another aromatic layer to the profile.

The result is a bouquet characteristic of Auto Purple: forest berries, ripe fruit, sweetness, a touch of earthiness, warm spice and a barely noticeable floral edge.

Reported Psychoactive Properties

For Auto Purple, Pyramid Seeds describes a combination of a euphoric onset followed by physical relaxation. This two-phase character fits well with the stated balance of 50% sativa and 50% indica.

The initial stage of the effects is associated in strain descriptions with an improved mood, emotional lightness and more active perception. Later, the relaxing component comes to the forefront, making the overall profile calmer.

With a stated THC content of 18-20%, Auto Purple belongs to genetics with noticeable psychoactive activity. However, a THC percentage alone cannot determine the subjective intensity of the effects in advance. Individual sensitivity, the amount consumed, tolerance and physiological characteristics all play an important role.

Main Characteristics

Auto Purple is a feminized autoflowering genetic line with an approximately equal ratio of sativa and indica components - 50% sativa and 50% indica. Pyramid Seeds states a THC level of 18-20%, while CBD remains low - below 1%.

Indoors, plant height can range from approximately 40-140 cm according to the manufacturer's data. For outdoor environments, a starting reference point of 60 cm is given. This wide range illustrates the phenotypic plasticity of the line: individual plants may differ noticeably in vertical development even within the same genetics.

The manufacturer estimates the complete cycle at approximately 65 days from germination. Under some LED conditions, an indicative figure of around 58 days is given.

The stated indoor yield is approximately 400 g/m², while for a specific LED configuration the manufacturer gives potential figures of around 700-750 g from an area of 1.5 m². Outdoors, the stated range is approximately 50-180 g per plant.

These figures should be regarded as manufacturer reference points. Genetic potential does not equal a guaranteed result: height, morphology, degree of pigmentation, development time and productivity depend on the specific phenotype and surrounding environment.

How Auto Purple Differs from Purple Fem

The main difference between Auto Purple and Purple Fem lies in their development pattern. Auto Purple belongs to the autoflowering category, while Purple Fem is the photoperiod version of the genetic line.

The stated THC figures also differ. For Auto Purple, the manufacturer gives a range of 18-20%, while Purple Fem is listed at around 22%. These values should be regarded as breeder specifications, since the actual cannabinoid concentration is determined by the specific plant material and can only be confirmed through laboratory analysis.

Direct comparison of their timelines also requires caution. Auto Purple is stated to have a complete cycle of around 65 days from germination. Purple Fem is listed at approximately 60 days of flowering specifically, without including a separate vegetative development period.

Potential plant size also differs. Photoperiod Purple Fem can develop considerably greater plant mass, while the autoflowering version is characterized by a more compact size range. At the same time, both lines retain the same overall Purple direction - violet colouration and a sweet berry-fruit aromatic profile.

Who May Find Auto Purple Interesting

Auto Purple is primarily interesting as an example of how visually distinctive Purple genetics can be transferred into an autoflowering format. Its main distinguishing traits are easy to define: violet pigmentation, a balanced indica-to-sativa ratio, berry-fruit aromatics and a stated THC content of 18-20%.

For collectors, phenotypic colouration is of particular interest. The appearance of Purple lines can vary noticeably, so comparing several plants from the same genetics clearly demonstrates how differently inherited traits can manifest themselves.

From a botanical perspective, Auto Purple is also interesting for its combination of pigmentation and morphological plasticity. The stated height range is fairly broad, while the intensity of the violet colour is not absolutely identical in every specimen.

Where the Genetic Characteristics Become Apparent

According to Pyramid Seeds, the characteristics of Auto Purple are described for both controlled environments and outdoor settings. For indoor conditions, the manufacturer specifies a height range of approximately 40-140 cm, while outdoor plants are described as starting at around 60 cm.

The external environment is particularly noticeable in the expression of colour. Anthocyanin pigmentation is genetically determined, but the intensity of violet shades can change under the influence of temperature and other factors. For this reason, a dark purple colour cannot be considered absolutely guaranteed for every plant based solely on the strain name.

Temperature, light intensity, available substrate volume, mineral nutrition, humidity and the characteristics of the individual phenotype all influence the plant's appearance. For this reason, Auto Purple is better understood not as a set of fixed parameters, but as a genetic line with a defined range of possible traits.

Producer

Pyramid Seeds is the seed bank under whose name Auto Purple is released. In the manufacturer's catalogue, this line belongs to the European collection and is positioned as one of the most recognizable purple autoflowering options.

The breeding concept behind Auto Purple is built around preserving the characteristic features of Purple Fem in an autoflowering form: violet pigmentation, sweet forest-berry aromatics and a balanced genetic profile.

When reading the strain specifications, it is important to distinguish the parameters stated by the manufacturer from the properties of an individual plant. The listed 18-20% THC, height of 40-140 cm, cycle duration and potential yield describe reference points for the genetic line, but they are not fixed values for every phenotype.
