Description

C4 was one of the first Fast Buds genetics to be released, and throughout the years has been subject to thorough selective breeding, resulting in what is now some of the most stable and potent purple genetics on the market to date. Made up of flagship traits from its parents, including short flowering time and vibrant flavors, C4 is a potent buttery tasting hybrid, with an Indica structure growing to a steady 100 cm in height. 

Bud description

Explosively compact and erupting in color. C4 buds are made up of rich purple leaves with wispy crystal-covered orange pistils.

Smoke report

A joyful balance of Indica and Sativa. The effects of C4 are therefore balanced and somewhat more mellow. Users will experience a light head rush to begin with, that slowly morphs into a more relaxing deep body high. Great for an evening relaxation or a bit of light meditation.

Plant Appearance

A bulky Indica that will develop multiple bud sites sparking rich purple buds tightly wrapping around the nodes and the stem. A resistant and forgiving plant with good internodal spacing. Growing up to 100 cm in height, she’s a hardy producer and will thrive even in the northern climates, indoors as well as outside.

Grow Tips

An easy-going plant that’ll be great for pros and beginners alike. Easily adapts to LST and other light training techniques. This hybrid will have a mixed set of effects, but leave her for just that little bit longer and you may find the effects to be more Indica and better for those evening smokers.

Taste

A complex tasting strain; a rich earthy/berry taste dominates the palette, that is softened by sweet buttery flavors making the smoke smooth and the overall taste sweet

She has a lovely smell
I have just finished curing my c4 auto and she smells lovely. The smoke is also very nice. But, the buds came out a bit airy.

C4
First off this strain was easy to grow and fast to harvest with heavy purple on all three plants. A great relaxing body high makes you feel like your walking on clouds lol. I personally give this grow a 3 because I screwed up a few thing I give the strain a 4 it’s able to put up with stress well the genetics are strong with this one. I give the overall grade 5 starts based on the ease of the grow and the product it produces.

Awesome Autoflower
I had the pleasure of growing one of these. Color was a vibrant purple. Smelled of berries and gas was wonderful growing this plant. I got about 2.5 oz dry from a 3 gallon pot. Smoke is very uplifting and taste great might I add. Overall a 7/10 for this strain. FYI it was my first Fast Buds strain will definitely buy more of these.

Question:
Q:
Hi, can I grow these in NFT? I read that you should not transplant an auto. So would I still use rockwool?
Answer:
A:
Hello, yes you can use Rockwool without any issues. Your plants will grow great, just make sure you check the EC so you don't overfeed your plants, other than that there shouldn't be a problem at all.

Question:
Q:
Is this a recommended strain for closet growth? If not, which strains do you suggest?
Answer:
A:
Hello! It depends on the space you have available, even though our C4 grows up to 100cm it may grow a little bit more depending on the growing environment but you can control it by tying down the branches or installing a Scrog net. Other strains we recommend would be Gorilla Cookies, Gorilla Glue and Rhino Ryder.

Question:
Q:
What size pots do you use if it is in soil???Are my 18l pots overkill??
Answer:
A:
Hi! We usually recommend 12L pots, 18L may be an overkill but there's no problem at all. If you want your plant to grow smaller you should use 5-7L pots.

Question:
Q:
on your site you say i can get 1.4 pounds per light, what light are you using for this and how many plants?
Answer:
A:
I would recommend using a 1000 watt light, with 16 plants this should get you around 1.4 pounds yield (very conservative estimate, if done properly should yield much more). Make sure to pack the plants tightly around the light and use good nutrients.
