Indica / Sativa — retail shopping guide
Indica 50%Sativa 50%
Indica, sativa and hybrid are a retail shopping convention — not a reliable guide to genetics or effects. When researchers analysed 89,923 commercial samples across six states, these labels did not predict a plant’s terpene or cannabinoid profile, and a genome-wide study found sativa- and indica-labelled plants to be genetically indistinct (PLOS ONE 2022; Nature Plants 2021). The labels are so fluid that AK-47, a hybrid, won “Best Sativa” at the 1999 Cannabis Cup and “Best Indica” four years later. For an accurate, genetics-true picture, see the chemotype above.

About Ultrashack
If it comes to the question what we are smoking the whole day then this is the answer! Heavy selected over years, has Ultrashack proven all his strenghtness in many grows. All starts with the parents: Kultranustra F1 （MK Ultra x Matanuska Tundra） and Shack F3 （Sannies Jack F3 x Shiva）
And some selections and testgrows to get: （（Shack f3 x Kultranustra F2） x Kultranustra F1）. Expect huge yields with a top smoke which is well balanced strong between stoned and high.
Taste and aroma arranged from grapefruit/berries/tropical/spices to floral and musk, very complex. The smaller plants are a bit more sweeter, I tried to fix this for more phenos in this strain.
Stretch is around 3x times, end height of most phenos is around 1m
