About

Extrema is an indica-dominant hybrid, running approximately 70% indica and 30% sativa, produced by crossing Chem Dog with The Herijuana. That parentage alone tells you a fair amount about what to expect: two cultivars known for potency and resinous expression, combined into a single genetic package that leans heavily toward the indica end of the spectrum. The aroma and flavor profile of Extrema reflects its lineage clearly. Pine and earthy notes form the foundation, with diesel character coming through from the Chem Dog side. Underneath those primary impressions sit secondary qualities of sweetness and spice that round out the profile without softening the harder edges. The terpene composition driving these characteristics is led by limonene, myrcene, caryophyllene, and pinene — a combination that accounts for the resinous, fuel-adjacent quality alongside the brighter piney and subtly sweet notes. THC content is measured in the 22%–27% range, placing this squarely in the high-potency tier. Users commonly report calming effects, which aligns with what you would expect from a cultivar this heavily indica-weighted with a terpene profile anchored by myrcene and caryophyllene. From a cultivation standpoint, Extrema is considered an easy to intermediate grow, described as a resilient cultivar — meaning it handles some environmental variability without dramatic consequences, which makes it accessible to growers still developing their skills without being a pushover for experienced hands looking for a reliable performer. Flowering time runs 8 to 9 weeks, or 56 to 63 days, which is a reasonable turnaround for a strain of this potency. Yield potential is high, with indoor growers reporting 500 to 600 grams per square meter under suitable conditions. That combination of manageable difficulty, solid yield, and strong THC levels makes it a practical choice for production-minded cultivators who do not want to sacrifice potency for ease. No progeny strains were included in the available data, so the breeding significance of Extrema at this time relates primarily to what it inherited rather than what it has contributed downstream. As a union of Chem Dog and The Herijuana, it represents a logical convergence of two well-regarded genetic lines into a stable, high-yielding package.
