Indica / Sativa — retail shopping guide
Indica 70%Sativa 30%
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 Insane Chem 91
Parental Information Chem 91 (clone only) aquired in NYC in late 1993, crossed to a Pre-Invasion Afghan (obtained on the Indus River in late 77 / early 78) during a hash deal. Large selection pool, all offspring tested. The best male from that cross was repeatedly back crossed to the Chem 91 (clone only) mother, to produce Chem 91 BX1, BX2, and BX3.
This strain is made up of ISP's Chem 91 BX2 (f) x ISP's Chem 91 BX3 (m).
Plain & simple, she's a Chem 91 on Pre-Invasion Afghan Steroids. All the potency, but with better yields.
This strain does not like: soggy grow mediums / being rootbound / or large pH swings. Does best grown in soil, peat moss, or coco. Hydro only for experienced growers. Describe each phenotype expression: Pheno # 1 (70 %): looks like a 50/50 mix of Chem 91 & a Pre-Invasion Afghan. Requires a 30 to 40 day veg, and 63 to 70 days of flowering for best yields. Cal-mag fed lightly from veg, thru the 4 th week of flowering. Feed moderate to heavy in both veg / flowering. Forms large main cola, with smaller golf ball sized buds on side branches. Heavy odor during flowering, predominantly Chemical Smells / Diesel Fuel with hints of Fruit / Citrus with Sweet & Sour undert
