The Red Family is the name given to the collection of seeds from the Sweet Seeds® seed bank whose flowers develop intense red, purple, pink, and even blue hues. This family now includes 12 members, the latest addition being Tropicanna Poison XL Auto® (SWS95). The fact that all these varieties share purple coloration is no coincidence. The key lies in the composition of these purple cannabis seeds, as they all contain anthocyanins, the compounds responsible for giving plants these striking colors.
After thoroughly studying this component, Sweet Seeds® decided to create an entire range of cannabis plants that shared these vibrant colors while offering completely different characteristics in every other aspect. As a result, any grow featuring a The Red Family seed will be visually stunning, while growers can also enjoy the benefits that anthocyanins bring to cannabis.
The Red Family Seeds
Sweet Seeds®’ collection of purple cannabis seeds consists of a total of 12 varieties that share the unique characteristic of producing flowers that develop different shades of red, purple, and blue as they reach maturity. The quality of these genetics is such that four of them have received awards: Bloody Skunk Auto®(SWS44), Dark Devil Auto®(SWS38), Devil Cream Auto®(SWS45), and Red Poison Auto®(SWS39).
This category is not limited to autoflowering seeds. It also includes photoperiod feminized varieties such as the powerful and exotic Red Hot Cookies®(SWS83), as well as CBD-rich genetics like Red Pure Auto CBD®(SWS81). New additions continue to expand the collection, including the highly promising Tropicanna Poison XL Auto® (SWS95), the latest member of The Red Family.

Sweet Seeds® has succeeded in ensuring that 95% of its plants display these eye-catching colors during the flowering stage. In fact, some specimens even develop colored leaves during flowering, making the plants even more visually spectacular.
To achieve this remarkable collection of exotic cannabis plants, Sweet Seeds® has worked—and continues to work tirelessly—on the genetics of its seeds. These varieties have undergone an intensive hybridization and selective breeding program to incorporate these genes and stabilize them.
The colors of a cannabis plant, just like all its other traits, are determined by its genetics. In this case, Sweet Seeds® worked with Pakistani Hindu Kush ancestral genetics originating from the Chitral region. Naturally, these genetics are also present in Tropicanna Poison XL Auto® (SWS95).
Why The Red Family Plants Develop Reddish Hues
The molecules responsible for these vibrant colors in purple cannabis genetics are known as anthocyanins. They are also found in dark-colored fruits and plants displaying autumn shades. There are many different anthocyanins, each capable of producing different color tones. They can even combine to create beautiful blends of hues within the same plant.

In cannabis, these molecules are present in the leaves, stems, flowers, and even some seeds. Anthocyanins belong to the flavonoid family, compounds that perform several important functions in plants, including protecting plant tissues from external stressors, regulating the transport of the hormone auxin, and releasing aromas that attract herbivores capable of dispersing their spores, among many other roles.
Both anthocyanins and flavonoids possess medicinal properties that are also transferred to cannabis. In fact, research has shown that some of these compounds remain present in both cannabis vapor and smoke. While Tropicanna Poison XL Auto® (SWS95) is not specifically known for its medicinal properties, its genetics naturally contain some of these beneficial molecules.
Tropicanna Poison XL Auto® (SWS95)
It is the feminized autoflowering version of Tropicanna Poison F1 Fast Version® (SWS85), developed by Sweet Seeds® itself. To create it, Sweet Seeds® selected an elite Tropicanna Cookies clone with a red-flowered phenotype and crossed it with its F1. Tropicanna Cookies is a “Super Strong” version of this renowned American genetic.
As a result, Tropicanna Poison XL Auto® (SWS95) is a variety with very high THC levels, reaching up to 24%, along with an equally impressive terpene profile. It is an exceptionally productive plant whose buds become completely coated in resin, delivering outstanding flavors and intense aromas. Among them, a delicious sweet mango-like flavor stands out, blending beautifully with earthy and woody notes over a subtle Skunk background.
The buds of Tropicanna Poison XL Auto® (SWS95) produce uplifting and stimulating effects that encourage creativity, making this strain an excellent choice for artistic activities or any task that requires focus and mental energy. Naturally, it is also perfect for enjoying with friends and sharing memorable moments.
The Ruderalis component (1.6%) of Tropicanna Poison XL Auto® (SWS95) shortens its life cycle, allowing it to be harvested just 8 weeks after germination. Growing conditions and environmental factors will influence its final size, which typically ranges from 60 to 120 cm (24–47 inches). These conditions will also affect yield. Indoors, it can produce up to 550 g/m², while outdoor plants yield between 35 and 125 g per plant.
