Every cannabis grower knows the magnificent varieties from the Sweet Seeds® seed bank, distinguished by their 99.9% femininity and for having undergone meticulous and exhaustive quality controls to ensure high productive and organoleptic performance. Among their extensive catalog, one of the most awarded genetics in recent years stands out: Green Poison® (SWS14).
This hybrid strain with strong indica influence has been crossed in different ways to result in two autoflowering varieties and another rich in CBD, as well as an F1 Fast Version® and a backcross with a red-flowered strain. Due to this genetic versatility, we explain below what each of them is like so that you can learn in great detail about a seed capable of producing robust plants, from which heavy and resinous buds emerge, offering fruity, sweet, spicy, and skunk flavors and aromas.
Green Poison®, high-performance cannabis seeds
Green Poison® (SWS14)
A true benchmark within the cannabis scene. Without a doubt, Green Poison® (SWS14) is one of the most important strains from this Spanish seed bank, whose success has been recognized over the last decade with a total of 18 awards. Some of the most important include first-place finishes at the Cannabis Canarias Cup, the XXII Copa de la Marihuana (AMEC), and the Festival 1422 in Argentina, among many other accolades.
This indica-dominant genetic variety stands out for its high production capacity, which can reach 650 g/m² indoors and up to 700 g/plant outdoors. It is a fairly easy-to-grow strain that develops correctly in any growing medium, whether it be soil, coco fiber, or hydroponics. It is characterized by rapid and vigorous growth, as well as by producing large, heavy, and spectacularly resinous buds.
Due to its psychoactive potency supported by a THC concentration ranging between 15 and 20%, the effects of this genetic are intense and long-lasting, presenting a balance between a considerable initial cerebral clarity and a pleasant subsequent physical relaxation. Likewise, its flavors and aromas denote different fruity, spicy, and sweet nuances, with a slight skunk background (notes of nuts and arugula).

Autoflowering varieties of Green Poison®
For beginner growers, as well as for cannabis cultivators who reside in areas with adverse climates or who simply do not have the time necessary to attend to their plants, Sweet Seeds® has managed to bring the main taste, olfactory, and psychoactive characteristics of the Green Poison® family to the world of autoflowering seeds. Below, we describe the two non-photodependent varieties that can be found in this seed bank’s catalog, differentiated by their size and productive capacity.
Green Poison Auto® (SWS30)
Green Poison Auto®, with a genetic code of 70% indica and 30% sativa, maintains the most representative properties of the feminized version, with the novelty that the life cycle of the specimens will be just 7 weeks from seed germination. It can be classified as an excellent option for cannabis growers with less experience, as it will not require great care to produce about 500 g/m² in closed spaces and 35 to 200 g/plant outdoors.
Regarding its family tree, it is worth noting that this 3rd-generation automatic strain is born from the hybridization of Green Poison® (SWS14) with another highly prestigious Sweet Seeds® seed, Big Devil #2 Auto® (SWS20). Once stabilized, to enhance the flavors and aromas of its parent, it is backcrossed twice with an original clone of Green Poison® (SWS14).
As with its other versions, this genetic exhibits a wide terpene range, which translates into tastes and fragrances that are difficult to describe and very pleasant on the nose and palate. Within its spicy touches, slight reminiscences of undergrowth and moss can be appreciated, intertwined with fruity nuances and, in certain phenotypes, even a slight aftertaste of cheese. The effects are also relaxing and uplifting, helping to stimulate creativity when performing creative tasks such as composing a song, playing an instrument, or painting an oil canvas.
Green Poison XL Auto® (SWS71)
The highest range of non-photodependent varieties from Sweet Seeds® is led by Green Poison XL Auto® (SWS71). Obtained through the hybridization of strains from different generations of the aforementioned automatic version, these seeds are capable of developing plants with a 25% greater height, as well as increasing the size of the flowers and their spectacular resin production.
With basic nutrition, water, and minimal dedication, this variety is very easy to grow and, above all, rewarding with a massive production for an automatic strain. It has an appearance that resembles a small Christmas tree, with fragrances that recall oriental spices and nuts like hazelnuts. Its buds exhibit a rather sativa structure, but they are as heavy and resinous as those of an indica.

Quality and great harvests guaranteed with the Green Poison® family
But the work of the breeders and geneticists at Sweet Seeds® does not end with these four versions of Green Poison®, as they have also incorporated a new strain into their The Red Family line that includes this genetic in its composition. This is Red Poison Auto® (SWS39), which has been crossed with an auto with purple and reddish flowers with Pakistani Kush ancestors. Extremely beautiful, it produces very heavy buds loaded with resin glands, with pleasant sweet and skunk aromas.
They also offer the Green Poison F1 Fast Version® (SWS41) variety, with an ultra-fast flowering of just 6 weeks indoors, while outdoors the harvest will be ready to cut at the end of August or the beginning of September. The plant’s appearance is totally hybrid with both sativa and indica traits, and its strong resistance to any type of fungus in outdoor crops is also worth noting.

Green Poison F1 Fast Version®
In short, the Green Poison® family can be described as one of the main hallmarks of the acclaimed Sweet Seeds® seed bank, which has up to six versions that include its genetics. Both for experienced growers and for those taking their first steps in horticultural work, it cannot be denied that these cannabis varieties are extremely productive and rewarding to grow, both in closed spaces under lights and outdoors with sunlight.
