Do you want to soar sky-high after you harvested a ton of amazing buds? In that case, look no further than C-47!

The feminized C-47 seeds are an F1 hybrid cross (60% Indica / 40% Sativa) between Critical Mass and a vigorous AK-47 cannabis plant.

These two extraordinarily stable and sturdy types of weed thrive under all circumstances and can be found in virtually every Dutch coffee shop.

The AK-47 strain may even have won the most cannabis awards. In addition, the Critical Mass is a robust plant with a very high mold resistance, so top rot does not stand a chance

Finally, thanks to the Skunk genes, C-47 is a potent strain with THC levels of up to 18%, making it suitable for any new grower and advanced breeders.

Keep on reading to learn more details about the many benefits this excellent strain has to offer.

Why you should buy C-47 feminized seeds

  • High mold resistance

  • Complex flavors

  • Excellent medicinal potential

Growing C-47 feminized seeds (indoor/outdoor)

These cannabis seeds can be grown both indoors and outdoors.

The C-47 strain can easily be placed in a SOG setup and subjected to a 12-12 lighting system.

During the growth, the fungus-resistant plant develops to a height of 80 cm to 120 cm indoors, with very thick buds that are so heavy that they may need to be supported to prevent them from breaking down.
C-47 is, in fact, an excellent hash plant. The buds have a pungent sweet smell and are richly covered with trichomes, lovingly nicknamed "disco balls". This makes the C-47 very popular among concentrate enthusiasts. Make sure you install good carbon filters to keep nosy bystanders at bay.

In addition, its thick branches and small internodal distance make it an excellent strain for cloning.

We recommend germination using the shot glass and paper towel method combined for the best results.

Flowering time

For indoor cultivation, growers need to anticipate a flowering time of about 10-12 weeks before harvesting her sweet buds.

Outdoor growers often choose to harvest in October after 70 to 84 days of flowering (in the Northern Hemisphere), when their buds are ripe.

Plant height

Grown indoors, these cannabis seeds grow into plants with a medium height between 80 and 120 cm.

Grown outdoors, your C-47 plants can stretch to a max length of 180 cm.

C-47 yield

C-47 cannabis seeds are capable of producing bountiful yields.

With methods like SOG, yields indoors vary from 450 to 550 grams per m²

Outdoors, yields can reach up to 700 grams per plant under optimal conditions, resulting in bags full of buds!


This Indica dominant strain offers surprisingly Sativa-like effects such as a cheerful, uplifting, and relaxed head high. With light inhalation, you remain active in a creative way.

The Indica genes provide an anesthetizing effect by which the weed can provide relief in many ways. Inhaling heavily will annihilate stress and result in a complete state of relaxation where you no longer leave the couch.

C-47 is an excellent choice for medicinal marijuana users since it can relieve various physical discomforts like nausea, headaches, and (muscle) cramps.

Mentally, the soothing tingling sensation and sedative effects are great for those suffering from anxiety, stress, or insomnia.

Side effects

Due to its remarkably balanced effects, C-47 isn't associated with severe side effects. That being said, a good coughing session might occur when you overdo it. Other than that, your only concerns are easily remedied dry eyes and a slightly parched mouth.

Smell and taste of C-47 feminized cannabis

The dominant terpene in Critical 47 is myrcene, followed by terpinolene, which is clearly reflected in the smell and taste.

C-47 weed is characterized by a refreshing citrus flavor profile with a deep skunk undertone.

The scent of subtle hints of cheese and earthy undertones nicely balances the predominantly fruity, citrus aroma.

Origin of C-47 marijuana plants

With parents like the globally acclaimed Critical Mass x AK-47, it's no wonder C-47 became an instant success.

Positonics first came up with this winning combo and perfected it for future generations.

Critical 47, as C-47 is sometimes referred to, now enjoys well-deserved recognition in many countries worldwide.

This is my second order, it's the second time they've been delivered at the earliest due date, and the second time they've been packaged discreetly. I've used many suppliers over the years, if you keep giving me service like this I'll never use another supplier. I've had a 100% germination rate, and you're the cheapest too.

Iva (Verified customer) 2019-11-01

Super happy with this seed bank. Customer service was super friendly and understanding, manyy thanks to Dave for the tips and help. My C-47's are now flowering and already start having lots of white on it and feel really sticky. I can definitely recommend this strain so far. Fairly easy to grow, nice buds and I assume a good yield.

Dahms (Verified customer) 2019-03-06

Great fast shipment, discrete envelope and germinated easy. Growing not that hard, but perhaps a little to hard for a first timer. Nice bud structure. Very dense and a bit snowy in the last few weeks so definitely recommend if you are planning to grow some quality weed

Hogan (Verified customer) 2019-01-29

Never heard of this strain before but I can strongly recommend C47. Pretty short flowering time and due to the high mold resistance I haven't experienced any problems with plant diseases. Harvests were very good !!

Dice E (Verified customer) 2018-11-11

Of the 20 seeds that I have bought, I am just starting to grow 4 plants. The other seeds are still in the fridge and I will use after this cultivation.

Hardesty Nadi (Verified customer) 2018-06-28

Had some issues with ordering to my postbox and the seeds didn't arrive. After having contact with weed seeds express they sent the seeds again so i had some delay (12 days or so) in receiving my seeds. Haven't start my cultivation yet so i can't say much about that part.

M. Dutton (Verified customer) 2018-06-11

Growing wasn't that hard actually so mayby the seeds are also suitable for beginners.

Anthony Austin (Verified customer) 2018-01-26

Very short flowering time which is perfect for my indoor cultivation. With 20 fem seeds i'm growing 17 female plants now and they are doing great.

Ranger (Verified customer) 2017-02-02

My C-47 strains did a pretty good job. I yielded around 525 grams which must be enough to smoke for a while I guess.
