Durban

!
Seed Bank: Sensi Seeds

This chunky subtropical Sativa is named after the South African port city of Durban and has been the dominant strain of dagga in the surrounding hills and plains for longer than anyone can remember. The genotype is favoured by local growers for yield and dependable, uniform flowering - across the region, thousands of kilos of Durban’s dark, distinctive Sativa buds are produced each year. In her homeland, Durban’s reputation among growers has been earned through a lifetime of first-class results and rock-solid reliability. Sensi Durban captures all these qualities in form that can flourish in temperate north as easily as in the tropical zones. Our acclimatised Durban is one of the purest Sativa seed-strains available today and she's very different from the tall, spindly, extra-sensitive Sativas found closer to the equator. Durban is heavy-branching, robust and even in the worst summer she can produce stunning harvests of sparkling, sticky buds with a distinct lemon-aniseed flavour. In her land of origin, this strain is known as Durban Poison when grown to her full potential. Naturally, Durban is as non-toxic as every other strain of cannabis, though her unusual power and the immediate rush with which it takes effect have occasionally been known to unnerve less experienced smokers. Many people report a unique effect from Durban which might be described as a ‘narcotic Sativa’. At higher doses it can induce a dreamy, red-eyed high that doesn’t weigh down smokers with the lack of energy or soporific effects common to comparably powerful Indicas.

  • Harvest outdoor: end of September
  • Height: 150-200 cm
  • Yield: up to 400 gr

Durban Poison

!
dp_dpoison
Seed Bank: Dutch Passion

Imported from South Africa, produced in Holland. Exclusively inbred, never hybridized, 100% Sativa. Large long budleaves, buds are also large and long with lots of resin. A sweet licorice or anise flavour. “Up” high similar to Thai. High yields. Well suited for outcrossing with late bloomers to produce earlier flowering. Also does very well under artificial light. A very popular variety.

  • Flowering period: 8-9 weeks
  • Harvest outdoor: end of September

Early Girl

!
Seed Bank: Sensi Seeds

This reliable, resilient seed-strain is the earliest outdoor Indica in the Sensi collection, aside from our auto-flowering strains. Early Girl has been a trusted name since the Eighties, known for dependably producing fabulous harvests of chunky, sparkling Indica tops in the short northern summers. Early Girl will flourish when given the basic essentials of cultivation, making her the ideal choice for balconies, roof-terraces or conservatories. Virtually any household will have enough room for a few of these beautiful, compact Girls - a metre or two of outdoor floor-space which receives sunlight in the day while staying dark at night is enough for this strain to demonstrate just how easy outdoor growing can be. With access to direct sunlight, regular watering and occasional feeding, Early Girl will do the rest herself, producing columns of fat, sticky, hash-flavoured buds with a smooth, long-lasting buzz. Afghani and North Indian strains give Early Girl her rugged mostly-Indica features and a delicate Sativa influence is inherited from a distant, high-altitude Mexican ancestor. Early Girl makes her largest buds on a single main stem. Most upper branches stay close, allowing their flower clusters to merge into the central cola. When her lower branches are left unpruned, they may reach almost as high as the main stem by the end of the outdoor season, so that their large, dense tops seem to ‘orbit’ the terminal bud.

  • Harvest outdoor: mid-September
  • Height: 150-200 cm
  • Yield: up to 250 gr

Early Pearl

!
Seed Bank: Sensi Seeds

As the first outdoor Sativa designed especially for shorter summers, Early Pearl has been providing northern growers with luxurious harvests of bulky, trichome-frosted bud for over 20 years. Before the development of early hybrids and acclimatised strains, producing powerful outdoor weed in Holland and similar climates was difficult. Though cannabis can grow anywhere, there was a time when seeds of truly psychoactive strains could only be obtained from imported weed. While often promising in their genetic potential, these seeds, especially the Sativas, had no chance of succeeding in the northern climate. Sensi’s three Early strains were developed and released in the mid Eighties to give cool-climate growers access to the three most important groups of psychoactive cannabis Early Skunk, Indica-dominant Early Girl, and Early Pearl to represent the Sativa side of the family. Each of those groundbreaking hybrids has its own advantages, and we would hesitate to choose an absolute favourite. If a choice had to be made, Early Pearl is a very strong contender, as she has the yield and solidity of an Indica, the dazzling high of a Sativa and a vibrant, unstoppable zest for life that’s all her own. Furthermore, the Early Pearl line has proven to be first-class breeding-stock, perfect for adding toughness and stability to other hybrids.
For the largest possible yield, Early Pearl can be started indoors at the end of winter and should be transferred outdoors to a location with maximum exposure to direct sunlight a few weeks after the spring equinox. Allow wide spacing between plants, especially if growing directly in the ground, as these ladies can attain a final height equivalent to a small tree. Except in cases of continuous rain or long periods of below-freezing temperatures at the end of the outdoor season, Early Pearl can be left outdoors to reach full-budded crystal-coated maturity.


  • Flowering: end of September
  • Height: 200-300 cm
  • Yield: up to 400 gr

Early Skunk

!
Seed Bank: Sensi Seeds

For excellent results and reliable outdoor performance, Early Skunk could qualify as the best all-round strain in the Sensi Seed Bank collection. She’s tough, fast and amazingly vibrant, able to produce lush, heavy harvests of dank, frosted bud in virtually any climate. Early Skunk brings together the bulk and vigour of Skunk #1 and the outdoor hardiness of Early Pearl in a turbo-charged cannabis hybrid that can grow happily in the garden, on the balcony or in any outdoor location with access to direct sunlight. It wasn’t so long ago that outdoor growers with short summers were unable to grow Skunks and other powerful hybrids to their full potential. To avoid poor weather at the end of outdoor season (which could cause fungus problems in extra-dense Skunk buds) growers in cool-climates were usually forced to harvest their most exotic plants before flowering reached its peak. Early Skunk was created to address this problem, and has been providing northern growers with the perfect solution to their dilemma ever since. The influence of the Pearl parent allows Early Skunk to finish weeks earlier than Skunk#1 and greatly increases the strain’s resistance to mould and fungus. Indica features dominate the growth pattern, giving a solid, resin-encrusted flower formation and massive yields. Early Skunk's Sativa side causes some extra 'run' in her thick arms of bud, and is strongly evident when sampled - imparting a smooth, buoyant high which blends with and lifts the warm, powerful Skunk stone, carrying it to new and interesting places.

  • Harvest outdoor: 1st week of October
  • Height: 200-300 cm
  • Yield: up to 500 gr

Guerilla's Gusto

!
Seed Bank: Sensi Seeds

This big, beautiful strain was developed and tested in northern Spain over several years. A handful of seeds from the best season made the journey from Spain to Holland, brought to Sensi as a ‘thank you’ from one of our thoughtful customers. Guerrilla’s Gusto started out as an unusual combination of radically different Indian strains from the north and south ends of the subcontinent. North Indian cannabis is classic Indica, while the less famous strains from the south are distinctly tropical with strong Sativa qualities.
To add gusto this hybrid and to give its offspring a chance to flourish in colder climates, it was paired with several Sensi parent plants well known for their ability to pass on toughness and vigour. Naturally, Skunk was an obvious choice, but there are some other very interesting (and possibly surprising) elements in the final version of the Guerrilla's Gusto seed strain, which combine to give her more power than her low price might suggest. Sensi’s final, acclimatised version of the Hindi-hybrid turned out to be even bigger, earlier and more resistant than we expected, which is how she came to be recommended as a variety for guerrilla growers.In spring, after seedlings have become established plants, Guerrilla's Gusto may be sown outdoors a sunny spot and then simply left alone. Provided plants have good soil and access to a reliable water source, they will need little or no care for the rest of the growing season. Naturally, growers should not expect these guerrillas to conceal themselves in the undergrowth. This is a large, husky variety which can reach an impressive height, especially when left to grow unhindered for the whole outdoor season.
Flowering: mid September
Height: 200-300 cm
Yield: up to 250 gr
