7 cannabis strains with uplifting effect

The energizing effect of some cannabis strains is, without a doubt, a true favourite among many users. This uplifting feeling – often called “high” – is often associated to Sativa genetics with high THC content, although other plants with different cannabinoid ratios can provide a very pleasant, social and creative effect.

For this reason, and within the myriad of feminised seeds available on the market, we have selected 7 marijuana strains that will increase your creativity and social side, improve your mood and motivate you to perform daily activities. We hope you’ll enjoy their vibrant energy!

5 Auto strains that you must grow

5 autoflowering strains that will surprise you

The quality of autoflowering (also known as automatic or simply auto) genetics have been greatly improved over the past years. Today, cannabis breeders develop top quality auto versions of some of the most acclaimed photoperiod varieties, so this type of genetics is being increasingly used by many growers.

Auto strains are ideal for those with small growing spaces, to make several outdoor crops per year easily or for those who have an outdoor growing space with light pollution (which can make it impossible to grow photoperiod strains). While just a few years ago the quality of these strains was mediocre, today you can find literally hundreds of autoflowering strains coming from the best genetics on the market.

We want to make things easy for you, that’s why today we present you a list of 5 extraordinary auto varieties that you should definitely try if you’re interested in this useful type of cannabis plants. New and classic strains, CBD-rich plants, high yielding genetics…you’ll find whatever you’re looking for!

7 fast flowering cannabis strains

Sometimes, you may not be sure about which cannabis strains to purchase for your next grow. Your personal taste and circumstances will greatly determine your decision, so while some of you may be looking for high yields or certain effect, others may prefer strains resistant to moulds or with the shortest possible flowering period.

In many occasions, the path followed by breeders to develop their genetics is similar, looking to fix certain traits in the offspring. Thus, today we’ll present a list of strains known for their early flowering trait. As you’ll see next, all varieties listed here have a bloom period no longer than 8 weeks, something that – on the other hand – doesn’t question their quality at all.

7 high yielding cannabis strains

Among the myriad of marijuana strains available on the market nowadays, some of them stand out for certain traits which have been fixed during the breeding process and that will determine the main characteristics of each genetics. The most desirable and sought-after traits are normally fast flowering, certain size or flavour or very high yield.

In this article we’ll focus on those cannabis varieties that stand out for their abundant production of buds, without a doubt one of the most desirable traits for growers. Indeed, you may know people looking for different flavours, or certain growth pattern, or a specified bloom period…but all of them love their plants to produce abundant harvests!

Cannabis trends in the USA (2017)

Marijuana trends in American dispensaries

Without a doubt, the USA have been a point of reference in the development of new and amazing cannabis strains ever since the decade of the 70’s, which normally take only a few years to become popular in Europe. Thus, and if we want to know which strains will be increasingly demanded in the near future in the Old Continent, we must definitely take a look at the current scene in the US.

Moreover, the legalisation in some States has led to a much more bearable situation for breeders and growers, who can now focus on developing new varieties without the worry of being caught by the Authorities. In this way, massive selections and large-scale breeding projects are being done today in the USA, which will doubtless led to a new generation of top grade marihuana genetics.

High yielding cannabis strains

Productivity of plants is one of the most frequently desired traits by cannabis growers. During the last years, yields have been improved thanks to successive selections and hybrids made by many breeders (seed producers).

What are the cannabis strains with best yields?

High yielding strains are normally Indica dominant plants with compact structure and tight buds. These plants are ready to harvest after 7-9 weeks of flowering, although they may need a more prolonged vegging period than plants with Sativa dominance.

Industrial Plant from Dinafem, Monster from Eva Seeds, Critical Kush from Barney’s Farm,  White Widow x Big Bud from Female Seeds, or Milky Way from Kiwi Seeds are some of the most productive feminised Indica strains.

On the other hand, we can also find high yielding Indicas in regular form: Bella Ciao from Tiki or NL5/Afghan from Mr Nice are a good example!

Session from Reggae Seeds

Of course, a number of mostly Sativa strains are also top yielders, as for example feminized vairieties like Moby Dick 2 from Dinafem, Easy Haze from Philosopher Seeds, Grapefruit from Female Seeds or Wombat from Blim Burn Seeds.

In the regular seed range we can find varieties like Bambata from Tiki Seeds or Session from Reggae Seeds.

There are other balanced Indica-Sativa hybrids with amazing yields, as for example Critical Jack from Dinafem and Big Foot from Sweet Seeds (both feminised) or Agent Orange from TGA Subcool (regular seeds).

Still, and as we already know, yields mainly depend on phenotypes (individual plants) rather than genotypes (varieties). Thus, the best option to ensure constant and stable production is to select the best phenotype within a batch of seeds and take cuttings from it. In this way we can keep a mother plant from which to take clones and have always the same excact results (as long as growing conditions are always the same).

Basic nomenclature of cannabis genetics

What is an IBL, S1, BX, F2, landrace, marijuana plant?

Often, when it’s time to buy cannabis seeds, the beginner grower can be confused by some acronyms that are written next to the name of the variety. Just with some basic concepts you will be able to get the correct choice between seeds with the same name, but different acronym.

There is a big difference between acquiring a second filial generation (F2) or an IBL, even if we talk about seeds of the same variety. These differences will condition the growth pattern of the plants, and also the final product, so that it is almost essential to learn exactly what is the meaning of these acronyms to be more accurate in choosing which seeds to buy, saving ourselves deceptions and getting closer to our preferences.

Pure Marijuana strains

Also known as landraces or purebreds, pure cannabis strains have been the basis of cannabis breeding over the past decades. These species are endemic from an area, where they have never been crossed (hybridised) with other varieties. There is a large number of landraces from all around the planet, belonging to any of the three families of cannabis, Sativa, Indica and Ruderalis. Nepal is a good example; in this country different pure strains of marijuana (mostly sativa) are grown and you can easily see the differences between genotypes basing on the sea level.

Each variety expresses its genetic code (genotype) with a certain growth and flowering pattern (phenotype), so that pure varieties – with a purest genotype – show great homogeneity, with just few differences between phenotypes. We can expect very little variation between landrace specimens of the same strain, getting plants with very similar growth, organoleptic and psychoactive traits. Good examples of these varieties can be Hindu Kush (Sensi Seeds), Colombia Punto Rojo (Cannabiogen) or China Yunnan (Ace Seeds). Continue reading

Characteristics of Sativa marijuana strains

Origins of Sativa cannabis strains

Cannabis cultivars coming from the tropical and sub-tropical areas of the planet – Africa, South and Central America and Asia – are normally called Sativa strains. These strains are then naturally found in countries like Colombia, Mexico, Brazil, Jamaica (Central and South America), Thailand, Cambodia, Laos, Vietnam (Southeast Asia), Malawi, South Africa, Kenya, Congo (Africa) and Nepal or India (South Asia), among others. Over time and generations, these Sativa varieties have developed specific traits that differentiate them from the others, either due to environmental conditions or breeding selections.

Cannabis Sativa was first classified by swedish botanist Carl Linneus in 1735.

Cannabis Sativa cultivation

The main phenotypic features of these strains are the long internodal distance, tall size, large and thin leafs with very narrow leaflets and long flowering periods that may range from 10 to 20 weeks, what makes their cultivation difficult for unexperienced growers, especially in indoor growing spaces. Almost all commercial Sativa strains have been crossed with Indica genetics to control these features, especially flowering time and size. Before the development of the first hybrid strains, Westerners basically smoked tropical Sativas smuggled from Colombia, Mexico, Brazil, etc. They were highly appreciated for their “high”, an energizing and inspiring effect only found in this type of strains, which is perfect to smoke during the day while we perform our daily activities.

Over time, and thanks to the first travellers to Asian countries, seeds from Indica strains coming from Afghanistan, Pakistan, etc. were brought to the West – along with new Sativa lines – thus enabling breeders to start developing the first hybrid varieties between their classic Sativas and the new Indicas brought from Asia. Basically, and since most Sativas were mainly grown outdoors, the first goal of many of these breeders was shortening the size and flowering period of their well-known Sativas, creating new strains more suitable for indoor cultures.

Indica marijuana characteristics

Geographical origins of Indica marijuana strains

We usually call Indica varieties those cannabis strains originary from Afghanistan, Pakistan, northern India, the Hindu Kush and some areas from Eastern Europe and the Near East. The Himalaya/Karakorum region is the originary place of most pure Indica genetics, which were brought to the West by the first hippies who travelled to Asia during the 60’s and 70’s and visited those places, where they met local growers and obtained marijuana seeds from them.

Most of these originary places are extremely isolated areas geographycally, so each genetic line could be bred and kept “pure” easily. In this way, we can find strong differences between genotypes grown in two different valleys in the same area.


Indica marijuana strain

As we already mentioned, the first Indica strains were brough to the West during the 60’s, so breeders had the chance to use these new genetic features to make Sativa plants more suitable for indoor crops . In this way, the first Indica-Sativa hybrids were created, with the initial aim to shorten the size and flowering time of the classic Sativas.

Cannabis Indica was first described and named by french naturalist Jean-Baptiste Lamarck in 1785, who based his description on plants from India.
