Alaskan Thunderfuck Feminized Seeds

The most powerful THC-filled

Exactly when Alaskan Thunderfuck came to be, no one can say. From stories floating around, this Sativa hybrid was brought to the Matanuska Valley in Alaska, where it was crossed with a Russian Ruderalis. In the late 1970s, an Afghani was introduced to improve its growth traits. Since then, it has become one of the best mentally stimulating and exhilarating hybrids you can buy. It is a hardy plant that can tolerate the cold (within reasonable limits), pests, and diseases.

Alaskan Thunderfuck feminized seeds grow more like an Indica, producing a generous yield of stunning, frosty buds – one of the fastest among Sativa-dominant genetics.

Note: This strain also goes by several other names, including Alaskan Thunder Fuck, ATF, Matanuska Thunder Fuck, and Matanuska Tundra.

More about Alaskan Thunderfuck Feminized Seeds

The vagueness of its origin, in some ways, added to its allure. But what keeps people coming back for more is its offering. Roll a joint or pack a bowl; the high comes nearly instantaneously. Relaxing but quite the joyride, as some enthusiasts would describe the effects of Alaskan Thunderfuck.

Mainly, the onslaught (in an invigorating way) begins seconds after a toke. Loaded with up to 20% THC concentration, the effects start with mental clarity and heightened sensations. You become more sensitive to the surroundings as if having a moment of awakening. As the mind soars to the sky, a sense of happiness descends upon you. Far from rendering you into a mindless vegetable, you go on a creative overdrive - able to pull ideas from nowhere.

Sitting around idly is the last thing you would find yourself in during this time. Alaskan Thunderfuck keeps your motivation up, provides you with the energy to get up and be physically active. Focusing on tasks at hand becomes more effortless.
Not more than half an hour later, a subtle, relaxing sensation envelopes your body. This physical buzz comes courtesy of Aghani genetics. The same genes that make this hybrid a joy to cultivate are also responsible for balancing the mental stimulation. And no, it does not condemn you to the couch in sheer bliss. Instead, you can continue on being productive, if you so choose.

Alaskan Thunderfuck feminized seeds have no problems growing in warm climates. More importantly, it can tolerate cold weather better than most other strains. You still need to keep the temperature within the recommended optimal range. For best results, try to maintain 75°F during the light-on period and 65°F during the light-off period. During the flowering stage, spanning 9 to 10 weeks, you can lower by 5° to stimulate more resin production.

The feminized seeds that you receive were hand-picked. It should not take more than two days to sprout. If you need help, you can follow this guide on the best way to germinate Alaskan Thunderfuck seeds.

This hybrid will thrive throughout the vegetative stage, developing sturdy stems and branches - all in preparation for the next life stage. Once you deem it the right time, switch to HPS and adjust the light cycle to 12/12. At this point, make sure that the growing area is 100% sealed from light leaks.

Top the plants early to control the height. At the very least, practice LST to improve the overall quality of the buds and boost yields. If you have the experience and feeling adventurous, try super cropping Alaskan Thunderfuck to coax the most out of the plants.

Indoors, you can expect around 1.5 ounces of buds per square foot - a sizable yield under normal circumstances. Meanwhile, this hybrid can grow up to 6 or 7 feet outdoors. Each plant can provide up to 3 ounces.


From 70% humidity level during the first week of the seedling stage, adjust the moisture level down to 50% by the end of the flowering period. The most important thing to do is never to make drastic changes. Lower by only 5% weekly. Once they begin flowering, you can further lower the humidity level down to 40%. Do this to avoid bud rot.

After you have grown Alaskan Thunderfuck feminized seeds, are its dried and cured buds purely for recreational use only? Absolutely not, because THC also produces plenty of medicinal benefits. Suppose you could preserve most of the terpenes. In that case, they each have unique pharmacological traits as well as enhance or heighten the effects of cannabinoids.

Most people use this hybrid to alleviate stress. Its ability to rush into the head and the body provides quick relief from the daily hassles of life. Anxiolytic and antidepressant properties may help patients who are battling anxiety attacks or depressive episodes. These psychological issues can also benefit from the relaxing and uplifting buzz that comes with a stimulating high.

Cancer patients and anyone suffering from neurological pain can also benefit from pain-relieving properties. Moreover, Alaskan Thunderfuck also can reduce inflammation.

When used moderately, this hybrid can energize consumers for a couple of hours or more. In this regard, one could counteract the effects of fatigue. Remember, though, that it should be in a safe environment. Never ever think about consuming cannabis for the wrong (and dangerous) reasons, such as keeping awake to drive.

One thing that you should also know is that Alaskan Thunderfuck can induce the munchies, so you want to have healthy snacks around. That makes it perfect for individuals trying to regain weight or needs a boost in appetite.

What are feminized seeds?

If you’re new to growing, you might not be sure what a ‘feminized seed’ is or why it's important. Here’s the deal. Marijuana plants come in both male and female sexes, but only one grows bud for smoking - the female plant.

Using them takes the guesswork out of growing. In the old days, you dealt with this by planting double the plants you thought you needed. Why? Simple
