Old School Classic

Hashberry needs little introduction. It created quite a stir in the cannabis community, was soon chosen as a High Times 'Top 10' strain by popular choice, and is still going strong. With this exceptional strain we offer growers an indica that combines the best of many traits. Hashberry is the unique result from a rigorous selection of desirable parents, with special attention paid to preserve the hybrid vigour our strains are so valued for. Its incredible power established a reputation as being 'hard to kill'. This strain grows to a medium height, is a good choice where space matters, and excellent for SOG. Hashberry not only has hybrid vigour but is also very heat resistant and easy to grow.

Hashberry develops a tight and heavy head bud with dense flowers along firm side shoots. Outdoor she grows into short, broad and bushy 'trees' with incredibly heavy colas that challenge any scale. Supersize bumper crops are possible in temperate to hot climates, a greenhouse, or a warm and dry autumn further up north. Excellent indoor 'cash crop' potential as well in all substrates. Very rewarding yields can be expected in hydroponic gardens.

Many plants cover their bud leaves with THC glands and this trim will fill your pollinator or bubble bags generously. Hashberry still remains easy to manicure and the dried buds have great 'bag appeal'. The buds reveal a refreshing fruity-floral scent during flowering. After proper drying and curing their fragrance transforms into a delicious hashy-berry aroma. The soothing indica high has long become a favourite among stoners and medical users alike.

Mandala #1

The #1 Choice for Early Outdoor: 35°- 55°N

Mandala #1 is a good choice if you are aiming for a quick crop with a sativa effect. We recommend this strain especially for northern climates where harvesting by the end of September is a priority. This strain has two basic phenotypes (characteristic plant types). Approximately 30% of the plants belong to the sativa dominant phenotype and grow in a christmas tree shape. The leaf structure is similar to the indica dominant pheno. Purplish leaf stems and light red stripes along shoots are not uncommon and should not be mistaken for a nutrient deficiency. The young flowering plants have a perfumed woody-herbal fragrance when you rub the stems. Despite the sativa dominance the buds are chunky and the plants are easy to grow. The indica type pheno is apparent through its more squat growth, thick main stem, and larger leaves. Branches are shorter, growing upwards close to the plant (perfect for SOG). The side shoots towards the top are also short and give the head buds a more compact structure. This pheno tends to develop a sweet-spicy smell during early flowering.

Mandala #1 flowers with a spear-shaped head bud of considerable length that makes this a high yielder. Resin output is impressive - also outdoor. The prime head buds are coated with a thick layer of trichomes and glisten brightly in the sun. Some plants develop beautiful dark purple calyxes during mid-flowering: a trait which they inherited from the New Zealand Purple Indica in the paternal line. Harvesting is very simple since the calyx-to-leaf ratio is predominantly high.

Outdoor: This early flowering strain shares the benefits of hardy landrace genetics and a very resinous hybrid to produce robust plants with high bud quality. Mandala #1 impresses with its high cold and pest resistance. The early flowering traits in this cross initiate bud development quickly enough for an abundant yield in September. Even if harsh weather circumstances require harvesting before all plants reach full maturity, they will still deliver a satisfying amount of resin-coated buds.
Greenhouse with basic heating: Recommended for exceptionally cold areas or above 55°N (for example Scandinavia, Russia).

Indoor: One of our breeding goals is to ensure that our strains are flexible and stable so that plants can be raised indoor and undergo the light stress of switching between artificial lighting and sunlight. It is therefore possible to start your garden indoor and shift the plants outdoor for flowering. Cloning and regenerating Mandala #1 is easy. Since this strain has a high percentage of landrace genetics that were adapted to growing on nutrient poor soil, the plants subsist easily in good horticultural grade potting soil and require little feeding if any. We recommend to provide an adequate pot size for healthy growth. Height is average and even the sativa pheno can be accomodated in small indoor spaces if a 12/12 light period is started early. A Sea of Green style cultivation is best with the Indica phenotype or with clones (rather than from seed) of both phenos. All plants are suitable for SCROG and other forms of training.

Takes You 8 Miles High

This is a fragrant, uplifting sativa that delivers quality harvests indoor & outdoor. Special attention was devoted to making this variety a low-maintenance plant that finishes by mid-October in northern climates. Flowering sets in quickly with most plants sexing within one week of switching to 12/12. Another positive feature is the fast and profuse resin production during early flowering that rewards your efforts right from the start. 8 Miles High has proven to be very reliable under various environmental stress factors such as abrupt changes in light and temperature. Plants can therefore be moved from indoor and planted out with no adverse effects. This strain is easy to grow and has no special requirements. It has shown good mold resistance and grows well in soil with minimal extra feeding, making it a good choice for growers with little experience or not much time on their hands.

8 Miles High has a great calyx-to-leaf ratio and slim leaves that make trimming the buds a quick job. Resiny bud production throughout the plant from top to bottom guarantees a quality harvest. The aromatic properties of this strain are delightfully diverse and feature the rare trait of strawberry fragrance. During flowering a slight brush against the plants releases a wonderful sweetness with an earthy undertone. This delicate aroma is followed by the more dominant piney freshness. As the plants mature you can also detect whiffs of a sweet lemonade scent. Cured buds retain the piney-minty smell but, in addition, there is a variety of delicious aromas ranging from strawberry, melon, to hash-candy. The smoke has a fresh minty taste and lingering sweetness to it. 8 Miles High lifts off straight to the head and triggers a lot of cerebral activity, with flashes of insights and long episodes of trippy visuals when you close your eyes and switch to auto pilot. This is a functional daytime smoke, or a wake-up call to keep you on your feet partying at night. The uplifting, almost euphoric, effect sets in once you reach maximum altitude. This energetic sativa glides back down smoothly and leaves an expansive feeling behind.

The indica-type females have minimum branching, medium tall growth, and are excellent for small spaces or cultivation in close rows. The sativa-leaning pheno can be grown as a multi-stem plant or trained if this is your preferred method of cultivation. It has longer branching due to the extended internodes and exhibits great potential as a big producer outdoor. For a sea of green set-up in hydro both phenos can be used. In hydro we recommend pruning the bottom branches on the sativa-leaning females so that all energy is focused on the long central cola.

Purple Paro Valley

  • Description
  • More Details
  • Specifications

World Exclusive Genetics

Purple Paro Valley was developed from a landrace Sativa that originates from the Paro Valley in West Bhutan at an altitude of 2.500 meters. The feminised hybrid is only two generations removed from the wild habitat. In this region the landrace has adapted to the harsh Himalayan climate of extended dry spells, monsoon rain, and cold winters. Purple Paro Valley (PPV) is recommended for cultivation in northern climates up to 56°N, or where high humidity is a concern. With global warming making outdoor cultivation increasingly unpredictable this resilient landrace hybrid can meet the challenge.

Thanks to her extreme durability she can cope with low temperatures better than most modern cannabis strains. At first glance her flexible branches look somewhat fragile and willowy. But the local Paro landrace can withstand strong wind. For the most part, Purple Paro Valley has inherited this feature. Nevertheless, it is recommended to support the plants if a storm is expected and not to wait and see! The mold resistance of the pure landrace and PPV is exceptionally high. The plants are also quite nutrient-efficient. Hybridising the landrace was essential to improve yield. Growing a large multi-branch plant will enhance yield further.

During flowering most plants develop a delicious spicy and green lime aroma. The citrus/lime scent is typical of the Paro landrace. But there is one type of plant that stands out and we call her “candy girl”, because she smells just like sugary candy! When you crumble the dry buds they release a sweet, minty scent with a touch of hazelnut. The green phenotype tends towards lavender. The terpene linalool is responsible for the lavender scent and enhances the sedative, sleep enhancing effects, as well contributing to pain relief. Some of the purple plants can also smell like black tea, but the smoke still leaves a fresh, minty aftertaste on the exhale. PPV hash oil has the fresh, sweet, balsamic aroma of Himalayan cedar wood. The high is predominantly very relaxing or couch lock. It’s suitable for winding down, as a sleep aid, great to relieve hyperactivity and nervousness.

Although the mother genetics are homogenous it did not turn out this way with the current feminised strain. This doesn’t have to be an undesirable factor. Diversity is an evolutionary strategy in nature to ensure survival. For that purpose, the diversity in PPV can play an important role in securing your harvest. We differentiate mainly between the green and the purple phenotype. The purple phenotype accounts for approx. 75% of the population and is very attractive and fascinating to watch during flowering. However, what ratio you get between green/purple largely depends on the amount of plants you are growing. A small number will give you a more slanted result. The green pheno is shorter in height, finishes flowering earlier, and the buds are also more compact. The purple phenotype has long internodes, which has to be taken into account when growing in containers or a greenhouse. Late planting and pruning is recommended in both situations. In a Mediterranean or hot climate the plants grow between 1.50 (green pheno) to 2 meters in containers if they are planted in June (northern hemisphere) and left unpruned. If a moderate size is desired, we recommend timing the planting season to allow for just one month vegetative growth. During this vegetative period pruning the main growing tip once should be sufficient. Purple Paro Valley responds well to LST (low stress training). Trimming the bottom shoots further simplifies plant care and increases the strength of the upper branches.

Purple Paro Valley is especially suitable as a “back-up strain” in unfavourable climates. For example, a few PPV plants can be combined with a higher yielding strain for the north such as our Mandala #1. In very difficult locations, or in a season with exceptionally bad weather, Purple Paro Valley is perhaps the only reliable choice. Where other varieties have already failed before, there is still hope with this special strain! For guerrilla cultivation she is also an attractive choice because hardly any other strain requires such low maintenance.

Belladonna

  • Description
  • Specifications

Belladonna is one of our original old school strains at Paradise Seeds. This classic plant is a multi award winner and is as popular now as when we introduced it 15 years ago thanks to a quick harvest time combined with a sativa high. When we released it at the end of the Nineties it quickly became an overnight classic with growers in the USA, Spain and the Netherlands due to its commercial potential and outstanding forum reviews. It is a versatile plant that will adapt effectively well to most environments and repay the grower with a combination of strength and yield. A great plant to grow, Belladonna continues to be a popular choice with indoor growers with a flowering time of approximately 9 weeks. The ease of management and characteristic low maintenance makes it a good plant for beginners seeking an upful harvest and keeps old school growers coming back for more too. The buds are tight and the foliage is reduced, giving this strain a good natural defense against mold and fungi. Belladonna is particularly recommended for growers with SOG set ups (Sea Of Green). This sultry sativa remains the seed of choice with many outdoor growers in both northern and southern regions. It does very well in warmer climates, such as California, where the sun fuels healthy growth, and was super popular when the outdoor growing revolution came to Spain in the 1990s. As this plant has been bred to be mold resistant, it is also a great bet (and a popular one) with sativa inspired gardeners in countries like the UK, Germany and the Netherlands. The resin coated buds that Belladonna delivers come with a heavy coating of trichomes, producing a plant that is beautiful to look at and fruity to taste. As for the effect, Belladonna produces a euphoria when smoked with a high that is psychedelic trippy and hallucinogenic provoking a strong rush to the senses.

Biddy Early

  • Description
  • Specifications

Biddy Early is the first outdoor cannabis strain from Serious Seeds. It's probably one of the best for outdoor cultivation in western European countries. As the name suggests already Biddy Early finishes very early, while it has also a very good resistance against mould, so perfectly suited for outdoor growing in the Dutch or similar climate. If the temperature is low, the plants will show red and purple colours. Biddy Early can reach a height of 2 meters under normal circumstances. Although Biddy Early is a fantastic plant to grow outdoors, it's also a good variety to grow indoors. Biddy Early has a great will to flower though, so keeping mothers in a vegetative state is very difficult, sometimes even impossible. Biddy Early has a sweet smell and a strong high.

Durban

  • Description
  • Specifications

This chunky subtropical Sativa from Sensi Seeds 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.

Early Girl

  • Description
  • Specifications

This reliable, resilient seed-strain is the earliest outdoor Indica in the Sensi Seeds 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.

Early Pearl

  • Description
  • Specifications

As the first outdoor Sativa at Sensi Seeds 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.

Early Skunk

  • Description
  • Specifications

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.
