Seb's take
Critical Mass crossed with Jack Herer, taking the latter's famous qualities and sharpening them further. Earthy wood on the nose with a lime-lemon bite; the high is euphoric and energetic, with an aroused edge that keeps things lively. She does the hard work herself — ideal for the inexperienced but keen.
Where it comes from
Delicious Seeds crossed Critical Mass with the famous Jack Herer, taking the latter's celebrated qualities and, by their own account, sharpening them further. The Critical Mass side lends the vigour and the yield; the Jack Herer side lends the pedigree. She grows beautifully and quickly, and largely does the hard work herself — a plant that suits the passionate newcomer rather than testing them.
Nose & flavour
Earthy wood on the nose, cut by a bright lime-lemon bite that lifts it well clear of the heavy end. A clean, woody profile with a citrus edge — more sharp than sweet, and none the worse for it. The kind of aroma that reads fresh and green rather than gassy or dank.
The high
Euphoric and energetic, with an aroused, lively edge that keeps things moving. A bright, upright high that lifts the mood and holds it there rather than sinking toward the sofa. Sativa-forward in character, and good daytime company for it — engaging rather than sedating.
Growing it
She completes her flowering cycle in just two months — 60 to 70 days — and begins to bloom so quickly that the deep green and white at the top arrives sooner than expected. The record gives no height, so I will note her temperament instead: fast, vigorous, and largely self-sufficient. Yields run to 500 g/m² indoors. She does the hard work herself, which makes her the ideal plant for the inexperienced but keen — keep an eye on her, and little more.
