About CBD Critical Mass Feminized
CBD Critical Mass is a CBD-dominant 41/59 cultivar with verified lab numbers of 8.7% CBD and 0.6% THC. That ratio matters: with THC well under 1%, CBD Critical Mass produces calm, focused, daytime-appropriate effects without the high you would get from a recreational strain. Customers who want the therapeutic and balancing qualities of cannabis — anxiety relief, focus, body relaxation — without psychoactivity choose CBD-rich genetics like this one.
Cannabinoid Profile
- Total CBD: 8.7% (lab-verified)
- Total THC: 0.6% (lab-verified)
- Dominant terpenes: Myrcene, Linalool, Pinene
Growing CBD Critical Mass
CBD Critical Mass feminized seeds flower in 9-11 weeks and produce 400-500g/m² indoors under standard lighting (~600 PPFD). Outdoors in full sun, expect 450-600g/plant. Plants reach Compact (2-3 ft) at maturity and are rated intermediate difficulty. Feminized genetics guarantee 99.9% female plants and the photoperiod growth pattern responds well to LST, topping, and SCROG training.
CBD-rich strains share the same cultivation needs as recreational cannabis — consistent feeding (EC 1.0–1.4 in veg, 1.4–1.8 in flower), 6.0–6.5 pH, and standard light cycles (18/6 veg, 12/12 flower). Final cannabinoid expression is most consistent when night temperatures drop 8–10°F below day temperatures in the last two weeks before harvest.
Effects & Best Uses
With only 0.6% THC, CBD Critical Mass delivers focused, calm sensations without the cerebral high of recreational cannabis. The 8.7% CBD content is what produces the felt effect: a smooth body-relaxation curve, mental clarity, and a gentle elevation of mood. This is the chemistry profile most often recommended for:
- Daytime use — focus and clarity without psychoactivity
- Anxiety, stress, and tension relief
- Mild pain management and inflammation
- Sleep support at higher doses (without next-day grogginess)
Terpene Profile
Dominant terpenes: Myrcene (primary), Linalool (secondary), Pinene (tertiary). High-CBD strains lean toward calming, grounding terpene profiles — Myrcene contributes a soft, resinous note while Linalool and Pinene add layered complexity that develops fully during a 3–4 week jar cure.
