GMO S1: A Savory and Funky Heavy Hitter

An improvement on the original GMO (also known as GMO Cookies or Garlic Cookies), GMO S1 offers a similar signature funk with impressive THC levels that set it apart from its predecessors. Pungent aromas of diesel and garlic backed by earthy undertones hint at the robust flavor and potent effects that this indica-dominant hybrid delivers.

With a lineage including Chemdog 91 and GSC, GMO S1 captures with best of its parents’ genetics, bringing savory notes of garlic, mushroom and onions and marrying them with a punch of gasoline that will not disappoint fans of the original GMO’s skunk.

Cultivating the GMO S1 Cannabis Strain: Grower’s Notes

The GMO S1 cultivar produces big dense colas, this plant likes to stretch once the flowering cycle is induced. Expect up to 3 x during the early flowering cycle, make sure you have no height restrictions, not ideal for tiered racking systems. These plants have thick, durable stems and but stretch once induced into flower, which will require multiple layers of trellising to support canopy.

Preferring a high nitrogen-phosphorous-potassium (NPK) soil or fertigation regime, the plants produce semi-dense, uniform colas with an large overall flower set size. To achieve a purple color shift, shift dark temperatures to 70 degrees Fahrenheit or lower in week 4-5, allowing for 2-3 weeks of cooler temps for full color expression. GMO S1 plants finish about a week earlier than the original, and have less susceptibility to pests and fungal infections.
