Description
Born from the cross of Durban Thai and Jack Herer, then refined with the legendary C99, Thai Herer 99 Feminized from Brothers Grimm Seeds carries serious sativa pedigree. The aroma blends earthy body with floral lift and a warm spice that lingers on the palate. Effects land energetic and uplifting, making it a strain that rewards active, engaged consumption. THC runs between 16 and 24 percent, offering a broad range that suits both newer growers and those chasing a stronger ceiling.
On the cultivation side, this is a large, vigorous photoperiod plant that demands space and planning. Indoors, growers can expect 450 to 600 g/m², a strong return for a well-managed tent or room. Outdoors, individual plants can yield 450 to 750 grams given the right conditions. Flowering finishes in 8 to 10 weeks, a manageable window for a sativa-dominant variety of this lineage. Being fully feminised, every seed is a productive plant, removing the guesswork at germination. For growers with vertical room and an appetite for classic genetics, Thai Herer 99 is a rewarding long-term addition to any rotation.

about this product
Thai Herer 99 brings legendary sativa genetics — Durban Thai, Jack Herer, and C99 — together in one high-yielding feminised package, ready for intermediate growers who want something worth growing.
The effects are firmly energetic and uplifting, which is exactly what you'd expect from a sativa-dominant cross built on Jack Herer and Durban Thai. THC sits between 16 and 24 percent, so the experience can range from a bright, clear-headed buzz to something more intense depending on the phenotype you pull. It rewards active, engaged consumption rather than a couch session.
Thai Herer 99 delivers a layered aroma of earthy body, floral lift, and warm spice that carries through into the flavour on the exhale. The C99 genetics contribute a brightness that keeps the profile from feeling heavy or one-dimensional. It's a satisfying combination for anyone who appreciates complexity over a single dominant note.
It's rated as a moderate-difficulty strain, which means it suits intermediate growers rather than complete beginners. As a large, vigorous photoperiod plant it needs proper space management and planning — indoors especially, training techniques like LST or topping will help keep height in check. If you've grown a few crops and understand the basics of canopy control, you'll be well placed to get the best out of it.
Indoor harvests typically land between 450 and 600 grams per square metre, which puts it firmly in the high-yield bracket for a sativa-dominant strain. Outdoors, well-developed plants can produce 450 to 750 grams per plant given enough space and a suitable climate. The pack size of 3 seeds gives you a solid starting point to select a strong phenotype without over-committing.
