Carbon Fiber is an indica-dominant hybrid bred by Phinest Cannabis and Cannarado Genetics. It stacks three well-known lines, crossing Biscotti with Cookies N' Cream and Grape Pie.
Its most notable trait is potency. Phinest's genetic library lists an average range of 26–36% THC, and the nursery's own writeup says Carbon Fiber can reach 36%. Phinest distributes the official breeder's cut as a tissue culture clone.
Biscotti, Cookies N' Cream and Grape Pie
Biscotti was originally developed by Cookies Farms. Leafly lists it as an indica-dominant hybrid from Gelato 25 and Sour Florida OG, testing around 21% THC.
Cookies N' Cream comes from Exotic Genetix, which crossed Starfighter with a Girl Scout Cookies phenotype. It took first place in the hybrid category at the 2014 Denver Cannabis Cup.
Grape Pie rounds out the cross. Leafly describes it as an indica-leaning hybrid of Cherry Pie and Gage Green Group's Grape Stomper, with THC around 24%.
Dark purple colas over a 63–73 day bloom
Phinest gives Carbon Fiber a flowering time of 63–73 days. The finished flower is dark purple with hints of green, and the nursery's writeup describes deep purple colas with vibrant color throughout.
The plant is tagged as a high-yield, high-THC cultivar that works indoors and outdoors. Phinest describes heavy harvests and flags the cultivar for its water-washing potential, which puts it in play for ice water hash as well as flower.
Seedfinder adds that the plant builds strong branches and stems with moderately spaced nodes. Buds can turn nearly black by harvest, with frosty trichomes and bright pistils, and the site rates it relatively easy to grow with good pest resistance.
Limonene, β-caryophyllene and α-pinene lead the terpene profile in Phinest's listing. The flavor lands as a subtle mix of berry and diesel.
Leafly's read on the effect
On Leafly, Carbon Fiber carries a 4.6 rating from 130 reviews. Leafly credits Cannarado Genetics as breeder and lists THC at 24%, with caryophyllene as the dominant terpene.
Leafly files the strain as a hybrid, and its reviewers describe a mostly energizing high. Talkative, aroused and euphoric are the effects they report most. That tilts away from what the indica-dominant label suggests, and Phinest's own notes lean toward euphoria and relaxation.
West Coast Cure, Legacy and other shelves
Carbon Fiber has moved well past the nursery. West Coast Cure sells it in California as a 7g bag of indoor smalls, crediting Cannarado Genetics as breeder. Its listing describes purple and green buds with amber pistils and heavy trichome coverage.
Legacy Cannabis also carries the strain and files it as a balanced 50/50 hybrid, writing the cross as (Cookies & Cream × Grape Pie) × Biscotti. Its terpene lineup starts with β-caryophyllene, limonene and β-myrcene, followed by α-humulene and ocimene.
Seedfinder records that Cannarado once offered Carbon Fiber as feminized seeds, though the breeder's shop no longer lists them. It puts typical THC around 25%.
A Phinest and Cannarado collaboration
Phinest Cannabis runs as a tissue culture clone provider under Phinest Distribution Company. Its genetic library groups Carbon Fiber with other cultivars credited to Cannarado Genetics, the Colorado breeder that Seedfinder dates to the late 1990s.
The two names also meet on Fatso, Cannarado's GMO × Legend OG cross, which Phinest carries in the same library. Phinest tags Fatso as a gas cultivar, while Carbon Fiber draws on the Cookies family and Grape Pie instead.
Phinest's spotlight on Carbon Fiber pitches the cut to growers chasing heavy yields and high test results. It frames the cultivar around big harvests, deep color and THC figures as high as 36%.
