Amsterdam Seed Supply – Buy Marijuana Seeds Online – ✓ Buy Cannabis Seeds Online ✓ Great Customer Service ✓ Cannabis Cup Winners ✓ Worldwide Discreet Shipping The selection of different types of cannabis seeds has changed a lot since the 90's. Breeders make a big effort to improve growers choices
Amsterdam Seed Supply began in 2002 in an attempt to save some of the fast disappearing ‘old-school’ genetics once the main-stay of the New Zealand/South Pacific cannabis seeds industry. New Zealands main crop up until the 1990’s involved a blend of genetics, mainly sativa, and Haze types bought back during the 70’s by travellers first discovering country’s such as Mexico, Thailand, Vietnam, India, Burma and Cambodia. These cannabis plants were typically tall, fast growing sativas that flourished in N.Z’s warm/wet climate and long autumn periods.
Cannabis seeds from Amsterdam
After years of selective breeding these original strains of cannabis seeds were transformed into names once so familiar to the N.Z smoker and grower. Names such as ‘Tepuke Thunder’ and ‘Coramandel Gold’ were common and when tested were shown to have some of the highest THC content of any outdoor plants anywhere. NZ quickly developed a name for itself as being one of the finest outdoor cannabis producers in the world.
What types of cannabis seeds are there?
Amsterdam Seed Supply has been leading the world in medical cannabis seed production. Our collection includes an extensive variety of cannabis seeds that can be used for treating several medical conditions. Auto flowering cannabis seeds are in almost all cases crossings (hybrids) between Cannabis ruderalis and Cannabis indica and/or Cannabis sativa. Amsterdam Seed Supply is one of the global leaders in producing high CBD/THC, stable feminized marijuana strains. We also have a great variety of regular cannabis seeds that will grow into female and male cannabis plants. We have a collection of indoor cannabis seeds that have been produced to thrive well in semi-artificial as well as artificial surroundings or grow rooms, and outdoor cannabis that will grow into select growing conditions. There are also cannabis seeds suitable to grow in greenhouses are usually a mix of Sativa and Indica genetics and are also perfectly suitable for growing indoors under lights.
Did you know that Amsterdam Seed Supply is the proud winner of several international awards, including over twenty Cannabis Cups. The success that we have accomplished today is the result of our hard work. We give away three free quality cannabis seeds with every order above 50 euro.
Different Types of Cannabis Seeds
The different types of cannabis seeds available in the market have drastically changed since the 90’s. Before, growers could only choose between indicas, sativas or hybrids in their regular version. Seed banks and breeders have done an amazing job investigating and creating new seeds. Nowadays, there is an unbelievable offer that adapts to anyone interested in cannabis.
Types of cannabis seeds
Indica strains stand out for their optimum yield/ life cycle ratio. They are, in general, more productive than sativas and need less time to complete their development, which is also shorter. Their main advantage is that these types of cannabis seeds grow very dense buds, but that also makes them more prone to mold, specially in humid and hot areas.
Cannabis species differentiate from each other in the characteristics they display during the different growth phases. Indica seeds grow into a spruce shape that reminds us of a Christmas tree. A good way to increase the yield is to use LST techniques or perform apical prunes to make sure light reaches all the parts of the plants equally. Dark green tones and wide leaves give indicas away.
Their short height makes these types of seeds perfect for indoor cultivation or small spaces. Although, their short flowering cycle also makes them ideal for outdoors, as they’ll be ready before first frosts.
Sativa cannabis is less productive than indica plants, which will require growing more plants in order to get the same amount. However, the buds are more spongy anr airy, which grants them greater resistance against humidity and mold. THC levels are higher in sativa seeds and effects are more mental and energetic. This quality plus their exotic and tropical flavors, make sativas very popular among growers.
Just like the buds, the entire plant is stretchy and airy. The light green leaflets are quite apart from one another. Due to their height and the amount of space they need, growing sativas indoors or in balconies is always challenging, as they require pruning techniques to modify vertical growth to horizontal.
Hybrid seeds are a combination of two different genetics, usually sativas and indicas, in order to improve strains’ characteristics. Hybridization’s goal is usually to shorten sativas’ flowering period and promote larger yields with dense and harder buds or grant indicas with exotic flavors and aromas.
Seed banks are constantly hybridizing strains to get new varieties and offer the best possible choices to their clients. When crossing two strains, you get different phenotypes, which essentially are plants with different characteristics but the same genes. Banks then choose the ones that meet the traits they are trying to stabilize and offer the best version.
Ruderalis seeds are less known because seed banks don’t usually sell them.They only use them as part of hybridization processes. A Ruderalis crossed with another type transforms the resulting seed into autoflowering once it is fully stabilized.
Ruderalis cannabis is a wild plant that originated in the coldest areas of north Europe, Central Russia and Siberia. The short hours of sunlight and constant frosts forced these types of plants to adapt to the environment and flower despite lack of light and harsh weather.
These types of seeds have THC levels lower than 3% and grow very little in comparison to other strains. They are compact, hefty and resistant and have a mere weed appearance. Buds are small and fat but their poor THC and CBD levels doesn’t pose any commercial interest apart from hybridizing it to obtain autoflowering plants.
Other types of marijuana seeds
Apart from all the cannabis species that exist according to the type of marijuana seed they come from; cannabis can also be classified in other ways according to their photoperiod dependence, gender or THC and CBD levels.
Regular seeds were the first ones used for cannabis cultivation. Their main characteristic is that they can germinate into male and female plants. This used to be a problem for people that wanted to get large yields out of their crops because these types of seeds used to turn male 90% of the time.
Males produce the necessary pollen for females to create seeds, which can then turn into new plants, but they also produce flowers. A pollinated female will yield poor quality buds full of seeds. A way to prevent this was to get rid of the male plants once they were identified. Currently, these types of seeds are limited to growers or seed banks that create their own hybrids.
Feminized seeds have been modified so that they are incapable of creating male chromosomes, growing only the female plants that produce flowers. Feminizing any type of marijuana seed is a difficult task that requires a lot of time and try-outs to ensure consistency and stability and be able to sell them as feminized varieties.
This process is nowadays 99.9% guaranteed, therefore, there is always a small possibility to germinate a male plant. However, any type of feminized seed is always a better option than a regular one for rookie growers. This way, growers avoid learning to differentiate male from female plants and be on the alert to remove the male plants on time. They also assure obtaining buds at the end of the cultivation process with just basic care.
Autoflowering seeds change phases regardless of their surrounding characteristics. They are auto programmed to enter the flowering period after a certain amount of growth weeks. They are very easy to grow because they can develop even with just a few hours of daily sunlight. As a matter of fact, they are very resistant to light pollution, which means interrupting their hours of darkness won’t affect them.
These seeds are perfect to start gaining growing experience or for people that don’t have enough time to dedicate to their plants. Of course, proper care will increase the final yield.
Autoflowering seeds are created by crossing a regular or feminized seed with a Ruderalis. This way, the new seeds will have a shorter life cycle, the plants will be smaller, more resistant and capable to flower under nearly any circumstance. These plants are ready for harvest 10-12 weeks after their germination. Although they are less productive than feminized, it compensates with the amount of autoflowering crops that can be carried out throughout the year.
All the different types of cannabis seeds of CBD have the same characteristics as feminized, regular or autoflowering seeds but with CBD levels higher than usual. On plenty of occasions THC levels are lowered to the maximum in order for the strains to be used for medical purposes.
However, these seeds aren’t suitable to make CBD based products because their THC levels are never as low as required by current regulations; which is at this moment 0.2%. Hemp seeds are more suitable for that purpose. Either way, CBD-rich marijuana seeds produce more relaxing and de-stressing effects than other seeds.
Contrary to CBD seeds, these types of cannabis seeds do have THC levels lower than 0.2%; therefore, CBD content is predominant. Also called industrial hemp, these seeds are ideal to extract CBD and create products for therapeutic uses. However, CBD levels provided by hemp seeds will never be as high as the one provided by CBD seeds.
Industrial hemp seeds aren’t suitable only to extract cannabidiol. Hemp plants are perfect to make resistant fibers for the textile industry, paper, insulating elements, ropes, motor fuels, paint, cosmetics, etc. Hemp seeds can be ingested in oil form, full, raw, toasted or in flour.
Fast version seeds
Just like CBD seeds, these types of cannabis seeds have the same characteristics as other marijuana seeds but their growth cycle is shorter than usual and they are intended to be harvested before October frosts.
Plenty of these seeds complement each other. Sativas, indicas, hybrids or Ruderalis can also be feminized, regular, autoflowering or fast version. Hemp seeds are only sativas.
