Yes it is
It's the grapefruit/pineapple C'99 from Female seeds
From their site:
The C’99 is the holy grail of the cannabis strains. As she resembles the high and the taste of an exceptional sweet landrace sativa, which normally takes half a year to flower. But the C99 flowers in 7 - 8 weeks. On top of that the buds are quite sugared.
This new batch is a cross of two exceptional basic phenotypes, the Grapefruit and the Pineapple. Both derived from the original Brothers Grimm C99.
Flowering time: 56 days
Height: 80 - 100 cm
Seed to Harvest: 75 day
Yield: high
Taste / Smell: Extremely fruity like a pineapple / grapefruit
nice mate the reason i asked is c99 is part of my next cultivars linage.
the following is my next cultivar which im about to germinate
Spliff Seeds - Snow White
We were experimenting for some time when we stumbled across this amazing Snow white pheno. A result of crossing our trusted Snow White (Northern Lights x White Widow) with a luscious Cinderella 99. This reinvented Snow White has an even higher high flower to leaf ratio, more compact growth and above all an even higher THC percentage. This makes here the perfect hybrid. She will form thick white hairs and will yield a large crop. First signs of flowering will show around the 3rd week. 2 to 3 weeks of pregrow is sufficient. She will stay nice and short with a length of around 60cm.
The buds are candleshaped, fat, enormous and have a greasy feel to them as a result of the THC production. The buds have been snowed under with resin and are real heavy weights. The main stalk is short and fat, which will support her heavy buds quite easily. She is a true Indica in appearance, shortstalked and darkgreen with oval fan leaves. Red stalks are quite common and often the juice flowing through these stalks is of a red brownish color. She is very stable in phenos with hardly to no variation. We have managed to shorten flowering time to about 8 weeks. Before it used to be up to ten weeks. She has few leaves so a delight to manicure. Snow White can also be grown outdoor. During both veg and flowering she is vigorous. A great plant for SOG in, for instance, a hydroponic system. Maximum yields can quite easily be achieved. A true cashcrop in every sense.
Snow White’s aroma is influenced by the Northern Light in a sense she has that typical earthy aroma, but with a hint of sweet fruit. Taste is sweet and fruity, resembling candyfloss. The high is truly powerful and narcotic. A real K.O. stoner. Medicinal value: muscle spasms, cramps, gastro-intestinal disorder, nausea, depression and stress.
