Our most popular strain of cannabis seed from Nirvana seeds of Amsterdam


White Widow

white widow cannabis plant

'
Her buds are powdered with crystals and she is extremely sticky to the touch'

 



SERIOUS SEEDS is committed to quality and good service. All of our strains have won PRIZES at cannabis festivals, 18 awards in total!! We only carry 5 strains but these are amongst the very best to be found on the market today. Germination rates prove to be nearly 100%!!!

Serious Seeds is a small firm, concentrating on the production of high-quality, stable and consistent varieties of cannabis seeds. Top quality smoking cannabis for our customers is the highest priority.

Independent and reliable lab tests (over 20 years of experience in this field) have shown that the different Serious Seeds strains produce the strongest plants (highest in THC content) available on the market today, averaging between 18-22% THC. These tests were done on plants grown from the same seeds as the customer gets.

Due to increased difficulties and expenses for seed breeders in Holland serious now contain 10 cannabis (weed) seeds not 15 and the prices have remained the same.

 We do not ship cannabis seeds to the USA 
Warning: Under Section 6 of the UK Misuse of Drugs Act 1971 it is an offence to cultivate any plant of the genus Cannabis in the UK without a license from the Secretary of State.

All seeds are sold as souvenirs only. Due to the fact that some countries legally allow growing of hemp seeds some specifics are documented. This data is normally distributed via the World Wide Web and is available internationally. No inference, association, affiliation or approval can be drawn from the distribution of web site or other media.

 
AK47
This easy to grow plant is our most popular. It is of medium height and produces good yields quite quickly. Extremely STRONG odor and smoke. Take extra care with odor control when growing near neighbors. The name was given not out of any idea of violence, but more in association with the ‘one hit wonder’ that the smoke is. Quality without compromise makes AK suitable for commercial grows or home use. These plants have a short flowering period for a sativa, producing compact, not too leafy buds that gleam with a coat of resin crystals.

BubbleGum

Bubble Gum is a medium tall, usually not too branchy (sometimes stretchy) plant, producing compact, crystal covered buds. Originally the Bubble Gum was developed by growers in Indiana, USA. From there the genetics moved to New England and eventually Holland. lt took many generations to finally produce this stable Bubble Gum, with the characteristic, sweet smell (truly resembling a typical bubble gum taste) and euphoric high; the original trademarks of this famous strain. The only inbred strain (no F1 hybrid) on the Serious menu.

Chronic

Our most commercial variety, this medium height, not too dense plant is the perfect combination of good yield and excellent quality. Smokers that know and grow choose this plant for its combination of appearance and sweet smell. With its indica background Chronic can produce up to 600 g/m2 without losing that connoisseur feeling. Grows a single huge central bud with few side branches. Do not top plants to encourage multiple big buds, as this strain does not respond well. Mild, sweet smell develops while flowering, take care to dry thoroughly after harvest (before packaging) to maintain this subtle fragrance.

3rd prize High Times Cannabis Cup 1994, improved in 2000.  

Of all our strains, this is the best choice for growers tired of losing quality when increasing yield.


Type: sativa/indica hybrid
Indoor clone grow time: 5 - 10 days
Indoor flowering time: 56 - 63 days
Indoor yield: 350 - 600 grams/m2
Outside/Greenhouse harvest time:

Kali Mist

Arguably the top sativa strain available today. With 90% sativa genetices, Kali Mist grows into tall, classically sativa plants with very few leaves. This strain produces dense clusters of full fluffy buds, producing much higher yields than you would expect. The plant structure and few leaves allow the light to pass all the way to lower branches, allowing bottom buds to develop fully. When planted outside early in the year this plant can grow very tall. Expect spiraling flowers with a high resin content and a delightfully spicy scent.

Kali Mist is often the choice of experts for their own stash grows.

Also, women particularly seem to like this strain, next to the sheer pleasure of smoking it, we received several reports that it works great against menstrual cramps.

We are proud to announce that Kali Mist was improved in 2000 to produce bigger yields. In Spain it proved to be very mold resistent, even outside during bad weather. This strain has flavor and subtle cerebral effect that gave it a Cannabis Cup first prize in 1995 (Hydro Cup) and again (with this new and improved version) in 2000 (Seed Company Sativa Cup)! Without a doubt the choice for connoisseur stash.
Gives a very strong, clear and energizing high.

White Russian

These seeds produce plants that are fantastic in both appearance and effect. Our most typically indica strain, White Russian is a stable cross of AK-47 and White Widow (a prize winning indica clone). Medium height, consistent plants and dense, very resinous flower tops (crystals appear after about 5 weeks of flowering). With such a strong indica background, the plants smell quite strong during both their growth and flowering period. In an independent seed comparison in which over 150 different seedstrains were grown out in a greenhouse, the White Russian came out as the strongest plant (22% THC, likely to be the strongest plant known at present!!).

Lowryder pot seeds


Newly released to the world, this unique variety will dramatically expand
the range of possibilities for aspiring, amateur and professional Cannabis
growers and breeders. Aptly named for its low profile (both literally and
figuratively), Lowryder was developed for extreme rapid growth (8-9 weeks
from seed to bud!
), uniquely short height (will grow no taller than 12 in!),
and amazing versatility.
