    Original Skunk No.1 Cannabis Seeds Feminized (Q.C.S.)

    Skunk  No.1 Cannabis Seeds Feinized

    Skunk No.1 was the first true stabilized hybrid to enter the Dutch Cannabis greenhouses. Sacred Seeds created it in the late 1970s from Afghani Indica, "Acapulco Gold" Mexican Sativa and Columbian Gold Sativa. For the first time this strain provided growers with the good taste and high of a sativa coupled with the quick heavy flowering of an indica. Having been successfully stabilized, Skunk No.1 has been widely used as a breeding parent for most of today’s leading "skunk" and many other strains. Skunk No.1 is very easy to grow and has always been seen as a standard against which others can be measured. Skunk No.1 produces dense buds varying in colour from light green to golden with a very high yield. Skunk No.1 is easy to manicure due to its high bud-to-leaf ratio. It has a sweet smell and taste with a cerebral high.

    Critical Cannabis Seeds Femiized (Q.C.S.)

    Critical Cannabis Seeds Feminized

    Key Features:  The ultimate cash crop that is easy to grow large yields in smaller spaces.

    There are always lots of requirements to fill when deciding which strain to grow: strength, yield, flavour, ease of growth, suitability to climate etc. There is one marijuana plant that tries to bring together all these features in a perfect balance in order to produce the ultimate cash crop: large yield, short flowering period, good smoke. Critical is a plant designed for the 'cash-crop' grower who wants the best of both worlds and is guaranteed to fulfil expectations.

    Our Critical plant is an Indica dominant genetic which shows in its small size, staying below 1 metre tall. It has short internode spacing, which will eventually fill up with buds, making it the high-yielding specimen it is. Its small height also makes it suitable for those looking to grow in small spaces, for the more discreet growers.

    Grown indoors, it will average 65-75 grams per plant and can easily hit 600 grams per square metre under a 600W light. Grown outdoors, it prefers a warmer climate such as in Spain, Italy or California and, given the right conditions, will produce over 100 grams per plant. Due to its relatively short flowering time, it can be grown in more northern latitudes (UK, Netherlands); however, it will not reach its full potential as she would indoors.

    No other plant  will yield as much in 7 weeks as Critical Feminized. This short flowering time makes it suitable for growers with a tight schedule. Commercial growers will be pleased with the results in sea/screen of green operations as it delivers large yields with very little maintenance.

    The final key to a good commercial crop is a solid smoke; it wouldn't make sense to have such a high-yielding plant with no power in the puff. Therefore we are glad to say that Critical offers just as much in the stone as it does in the yield. It brings a nice stoned effect which mellows you down into a relaxed vibration.

      OG Kush Cannabis Seeds Autoflower (Q.C.S.)

      OG Kush Autoflower Cannabis Seeds 

      We thought it would be awesome to create an autoflower OG Kush and tried many different autos to crossbreed the OG Kush to get the result they were looking for. Ultimately the NL Auto X OG Kush cross came out a clear winner. This was no surprise as both strains share ancestral roots.
      The result; an OG Kush automatic that is a big yielding autoflowering strain with impressive bud formation and trichome production. Bud structure is quite similar to your typical Kush buds.
      The OG Kush Automatic has a balanced effect. A potent and long-lasting body one that is also quite cerebral. Her aroma offers a lovely balanced acidity with clear notes of sweet lime with a lingering hint of diesel, revealing the Chemdawg origins of the OG Kush.
