C4 is a sought-after hybrid strain created by crossbreeding Cotton Candy and Shishkaberry, two equally delicious strains. The result is an Indica-leaning cultivar boasting a complex blend of flavors and versatile effects. C4 manages to bring together a whole array of flavors and aromas, with most of the attention being claimed by sage, citrus, and earthiness. The effects come on fast, engulfing consumers with uplifting euphoria while their body slowly goes numb. Prepare for proper sedation, possible sleepiness, and the munchies. Medical use of C4 should be aimed at easing anxiety-related issues, including PTSD, and migraines. Growing these plants is no walk in the park, but the rewards are plentiful, and the whole process is a joy to watch. Expect medium-tall plants that exude an intense aroma towards the end of the 9 weeks of flowering and nice yields, both indoors and outdoors. Don’t take odor control too lightly.

The C4 Auto from FastBuds was a standout strain for me. Its unique blend of fruity and earthy flavors creates a smooth, satisfying smoke that I haven’t found in many other strains. The terpene profile is rich and complex, making each hit enjoyable. The plant itself was a beauty to grow. It stayed compact but packed on dense, resin-coated buds. By the end of flowering, the frost was impressive, and even the leftover trim looks like it will deliver some strong extracts—definitely a double bonus! For anyone looking for a resilient, easy-to-grow strain with strong flavors and solid yields, I’d highly recommend C4 Auto. I’ll be growing it again for sure!

Hallo zusammen 🤙. Sehr schöne Pflanze Das High ist ganz angenehm. Der Geruch ist ziemlich stark aber kann es nicht zuordnen. Die Weißen Blüten sehen schön aus aber das war es auch schon.

C4 is one of my favorite varieties, I like its aroma spicy with pepper, creamy, orange juice is felt on the tongue, after evaporation it smells of incense in the room)) The effect is mild bodily, relaxing, but sometimes there are bouts of laughter 😂

I’m personally happy with this Strain it’s my 2nd grow and it yielded more than my first. This one had immense resistance as I topped her she seemed to laugh at me. The colour, smell, taste, high it’s all there, the terps blow your head off when you grind it(smells heavily like lemony/fruity/minty almost with skunky/earthy undertones). Had 65grams dried curing steady at 64-62% for a week, after 9 days I had a 0.5 joint and I was smacked. Shit alleviated a tone of bricks and anxiety from my already hectic life. This strain is straight medicine for me needless to say I will smoke it to the very last piece of dust :) It was exactly what I was looking for.

She grew like a champ! Loving FastBuds Genetics. Grew 3 plants from them (2 harvested and another growing) and I can say that they are very good genetics to work with when it comes to autoflowering cannabis plants. Wet trimmed as I was concerned about humidity in my current tent situation. Currently drying in a small home made tent at around 18 degrees Celsius and RH around 68% (I know it's a bit high) but going down gradually. Kept only the best looking buds. All trim and larf was frozen fresh to make bubble hash later on.

I'm not sure if it's the novelty of smoking 'not green weed', but I get lots of requests for this. Also happens to be one of my favorite stations

Not as tasty as my last C4 run but definitely more potent. A great hybrid effect, nice relaxation and tones the anxiety waaaaay down. A bit more indica feels push through as time passes, great effects. Overall, not bad!

This stuff is 🔥! Dried out and steady at 64% in the jar, I took a couple nugs out and rolled a doob. I smoked half of it, I'm toast 😆 nice head effects, body relaxed but not slumpy by any means, great smoke!

The C4's turned out exactly as they were supposed to. They were autos so they didn't get very tall but their buds are still fatter than some of the photoperiods I've grown. If fruity purple bud is what you're after, I highly recommend this strain.
