Sweet Seeds® has become a true reference for the most selective and distinguished cannabis cultivators, thanks to their constant and exhaustive research, selection, and genetic stabilization work, which has led to the creation of numerous feminized and autoflowering marijuana seeds with recognized prestige in the cannabis scene. For this reason, the team of writers and cultivators at GB The Green Brand aims to highlight eight strains, which, according to their judgment, can be considered the best Sweet Seeds strains.
What are the best feminized seeds of Sweet Seeds® according to the team at GB The Green Brand?
Within the feminized and photoperiod-dependent varieties available in the broad spectrum of Sweet Seeds® genetics, it is essential to highlight the extraordinary production quality of all these strains, as well as the different chemotypes—terpenes and cannabinoids—that meet the needs of all types of cultivators and consumers, both recreational and medicinal. Among these, there are four strains that are of great relevance in the cannabis industry: Cream Caramel® (SWS04), Crystal Candy® (SWS58), Mohan Ram® (SWS09), and Psicodelicia® (SWS07).
Cream Caramel® (SWS04)
Considered one of the most prolific marijuana strains in Sweet Seeds®’ history, Cream Caramel brings together the best qualities from different indica genetics, such as Blue Back, Maple Leaf Indica, and White Rhino. It is the most awarded cannabis plant in the entire catalog of this seed bank based in Valencia, having won over 25 trophies and cups from 2007 to 2018, including the Barcelona Breeders Cup, VI Copa THC Valencia, II Copa del Rey de Bogotá (Colombia), Cannabis Champions Cup at Spannabis, and Coppa D’Italia Cannabica in Rome (Italy), among many others.
It is considered the preferred strain for medical cannabis consumers who seek high THC levels, which result in psychoactive sensations perfect for body relaxation and as a complementary treatment for depression and stress. With a 90% indica dominance, it is also known for its earthy aromas and sweet, caramelized flavors, along with its robust structure with small internodal distance and great lateral branching.

Crystal Candy® (SWS58)
Born from an unknown cross between different feminized strains, Sweet Seeds®’ R&D Department named this genetic Crystal Candy® (SWS58) due to its remarkable ability to produce incredibly aromatic resin crystals. It stands out for the high density of its trichomes, as well as for sweet fragrances that blend with sugary flavors reminiscent of sour strawberry gum and melon candy.
In terms of genetic distribution, this poly-hybrid guarantees balanced and pleasant effects, showing a 60% indica and 40% sativa composition. Outdoor yields can reach 700g/plant, possibly surpassing this amount if cultivated by expert hands in the noble art of horticulture, while indoor yields can exceed 500g/m2 even under basic treatments. It has also been awarded in various competitions, such as the Spannabis Champions Cup in 2017, held in Barcelona.
Mohan Ram® (SWS09)
Created from the hybridization of S.A.D. Sweet Afgani Delicious® (SWS02) with an elite clone of the renowned White Widow strain, this is an 85% indica-dominant strain capable of delivering potent and long-lasting narcotic and sedative effects, ideal for both recreational and therapeutic use. Mohan Ram is easy to cultivate both indoors under lights and outdoors, with THC levels ranging between 18-21% and a significant CBD content of 1.4%. The flowering period for indoor cultivation is just 8 weeks, while outdoor plants will be ready for harvest, drying, and manicuring by the end of September in the Northern Hemisphere.
The numerous awards and accolades it has received over the past decade cement its status as a well-established and renowned cannabis variety among cultivators and smokers worldwide. Some of the prestigious titles include the XIV Copa Cannábica del Plata (Argentina), Portugal Weed Masters, Copa Cultivadores de Zion (Argentina), Copa Cannabis de Uruguay, and XIV Copa de la Marihuana (Madrid, Spain), among many others.
Psicodelicia® (SWS07)
This feminized variety from Sweet Seeds® was achieved by crossing a cutting from the United States with a Nepalese landrace that carries intense spicy aromas. Psicodelicia features a 70% sativa hybrid genetic composition and is characterized by producing tight, dense buds covered in sticky and fine resin, alongside citrus aromas that combine with coffee and forest undertones.
It won the third prize in the indoor category at the Copa Litoral de los Poetas 2016 (Chile), where its high production capacity (up to 600g/m2 indoors and around 700g/plant outdoors) and significant psychoactive potency (15-20% THC) were recognized. These effects result in stimulating and energetic sensations, making it ideal for engaging in creative and artistic tasks.
Best autoflowering varieties of Sweet Seeds® according to GB
On the other hand, in recent years, Sweet Seeds® has expanded its range of autoflowering varieties, significantly improving the productive, psychoactive, and organoleptic qualities of these high-level hybrids. Due to these improvements, as well as the increased discretion and ease of cultivation both indoors and outdoors, these non-photoperiod-dependent strains have gained increasing popularity over the last decades. In this article, GB The Green Brand highlights Sweet Gelato Auto® (SWS76) and Big Devil XL Auto® (SWS28).
Sweet Gelato Auto® (SWS76)
This 5th-generation autoflowering variety belongs to the most distinguished selection of varieties from the California bay area, particularly standing out from the rest is Gelato (Sunset Sherbet x Girl Scout Cookies “Thin Mint”). To create this autoflowering version, Sweet Seeds crossed Gelato with Killer Kush Auto® (SWS56), which brings a powerful OG Kush lineage.
One of the main qualities of Sweet Gelato Auto® (SWS76) is its pleasant fruity aroma with kush notes, interwoven with earthy and woody flavors reminiscent of different nuts like hazelnuts and almonds. It also shows other more mentholated and citrusy touches, making it an excellent option for making cannabis concentrates such as BHO and rosin. Outdoor yields can exceed 100g/plant, while indoor yields can reach up to 500g/m2, after about 8 weeks from seed germination.
Big Devil XL Auto® (SWS28)
A 3rd-generation autoflowering variety, Sweet Seeds® breeders and geneticists have managed to stabilize this well-known cannabis strain by crossing Big Devil #2 Auto® (SWS20) with an auto Jack Herer strain. This has resulted in increased height, more lateral branches, and thicker, denser buds covered in a spectacular aromatic resin.
The flavors and aromas from the beautiful flowers of Big Devil XL Auto combine an incense-like touch with refreshing citrus notes reminiscent of lemon. Outdoors, its yield can reach impressive levels for an autoflowering variety, exceeding 150g/plant. As for the awards this non-photoperiodic variety has earned, it was named Auto of the Year at the High Life Cup by Soft Secrets, in addition to taking first place at the Copa Cannábica Expogrow 2014 in Irún and second place at the Copa Esmeralda 2018 in Colombia.
Best CBD-Rich Varieties of Sweet Seeds®
The number of users, both cultivators and consumers, of CBD-rich varieties has grown significantly in recent years, as the scientific community continues its hard and consistent work to demonstrate the various therapeutic benefits of cannabinoids like cannabidiol (CBD) and THC. Some of the conditions that can be treated with CBD-rich strains include stress, insomnia, anxiety, nausea, inflammation, spasms, and muscle pain, among many others. In this regard, GB highlights two acclaimed genetics: Green Poison CBD® (SWS70) and Sweet Pure Auto CBD® (SWS75).
Green Poison CBD® (SWS70)
A fast-flowering feminized variety (7 weeks), Green Poison CBD exhibits a genetic distribution of 55% indica and 45% sativa. The THC:CBD ratio of this strain ranges from 1:1 to 1:2, with THC levels of 5-9% and CBD levels of 5-12%. Outdoor production can reach up to 700g/plant, while indoor yields can reach 600g/m2. It stands out for its vigorous and fast growth, as well as for its prominent central cola with long secondary branches. Regarding its family tree, this strain was obtained by crossing Green Poison® (SWS14) with a CBD-rich clone with a clear Diesel influence.
Sweet Pure Auto CBD® (SWS75)
Sweet Pure CBD® (SWS65) x Honey Peach Auto CBD® (SWS64) results in a 6th-generation autoflowering strain, considered the first autoflowering variety from Sweet Seeds® with THC content lower than 1%. Additionally, Sweet Pure Auto CBD shows CBD percentages of up to 20%, resulting in a THC:CBD ratio between 1:15 and 1:23. Designed for therapeutic consumers, the minimal THC content provides medicinal benefits without causing any altered state of consciousness. Its aromas and flavors are primarily fruity with citrus undertones, combined with earthy notes reminiscent of cypress.
