Strain Description:

Critical Jack Herer delivers the uplifting mental effects of a true Sativa with none of the jittery edge. It begins with sharp mental clarity and evolves into a calm, centred buzz that’s perfect for both productivity and peaceful downtime. With THC levels around 21%, the high is pronounced but balanced, avoiding excessive stimulation or sedation. The buds are dense and resinous, emitting a classic Jack Herer aroma—minty, spicy, and woody. This version flowers more quickly and with higher yields than a traditional Herer, thanks to the Critical Mass genetics enhancing structure and speed.


Growing Information:

Designed for versatility, Critical Jack Herer performs well indoors, outdoors, or in greenhouses. Indoors, the flowering time ranges from 60 to 70 days, producing large, resinous colas with minimal trimming required. Outdoors, plants can reach impressive heights and deliver up to 900 g per plant when grown in full sun. Its structure features strong branching and narrow Sativa-style leaves, allowing light to penetrate deep into the canopy. This is a low-maintenance, high-performance strain suitable for growers at all experience levels.


Strain Flavour and Aromas:

This strain offers a sophisticated blend of aromas and flavours. Menthol and pepper dominate the scent profile, supported by sweet incense that evokes a church-like ambience. Once ground, the aroma becomes richer and more intense. The flavour follows with a bittersweet blend, a sharp lemony finish, subtle hardwood notes, and that unmistakable Jack Herer incense character, creating a refined and satisfying smoking experience.


Strain Lineage:

By pairing Critical Mass—a strain prized for its short flowering time and heavy yields—with Jack Herer, one of the most iconic Sativa hybrids of all time, Delicious Seeds has created a fast-flowering variant that retains Jack’s cerebral sparkle while boosting yield and structural integrity. This stable phenotype is easier to grow than a pure Sativa while preserving the signature aroma and uplifting effect that made Jack Herer a legend.


Strain Summary:

Critical Jack Herer by Delicious Seeds is a versatile, flavour-rich, and balanced Sativa hybrid offering exceptional yields and refined effects. Its fast flowering, strong branching, and complex aromatic profile make it a reliable performer indoors and out. Ideal for both recreational and medicinal users, this strain is equally suited to daytime productivity and relaxed social settings—delivering clarity, creativity, and calm in a single smooth hit.
