Insane Chem 91
Also known as: IC91
Insane Chem 91 Strain Overview
Insane Chem 91, also known as IC91, is a predominantly indica hybrid strain developed by Insane Seed Posse that represents a refined version of the legendary Chem 91 genetics. This strain was created through a meticulous breeding process that involved crossing a Chem 91 clone-only cut (acquired in New York City in late 1993) with a Pre-Invasion Afghan landrace obtained on the Indus River in the late 1970s during a hash deal. The resulting offspring underwent multiple generations of backcrossing, with the best male being repeatedly backcrossed to the original Chem 91 mother to produce BX1, BX2, and BX3 generations. Insane Chem 91 is specifically composed of ISP's Chem 91 BX2 (female) crossed with ISP's Chem 91 BX3 (male), described by the breeder as 'Chem 91 on Pre-Invasion Afghan Steroids' with all the potency of the original but improved yields. The strain maintains the iconic diesel, chemical, and citrus aromatics of its famous parent while adding the robust structure and enhanced resin production characteristic of Afghan genetics. This careful breeding work has produced a strain that honors the legendary Chem 91 lineage while addressing some of its cultivation challenges, making it more accessible to growers seeking the classic Chemdog experience with better performance characteristics.

Insane Chem 91 Strain Growing Information
Insane Chem 91 is suitable for indoor, outdoor, and greenhouse cultivation with a flowering time of approximately 67 days (9-10 weeks). The strain is predominantly indica and tends to stay more compact than pure sativa varieties, though it can still reach considerable height outdoors. It requires careful attention to growing conditions, performing best in soil, peat moss, or coco substrates, with hydroponic cultivation recommended only for experienced growers. The strain dislikes soggy growing mediums, being rootbound, and large pH swings. It benefits from Cal-Mag supplementation lightly from vegetation through the 4th week of flowering and responds well to moderate to heavy feeding in both vegetative and flowering stages. Plants typically require 30-40 days of vegetative growth for optimal yields and form large main colas with smaller golf ball-sized buds on side branches. The strain produces heavy odors during flowering with predominantly chemical and diesel fuel scents mixed with hints of fruit and citrus. Yields are described as improved compared to the original Chem 91, though specific numbers vary by growing conditions.
