About London OG
Holy Smoke Seeds combined Flamethrower OG, Mob Boss, and Guide Dawg to build London OG, an indica with a three-way parentage that's unusual compared to the simpler two-parent crosses common across most modern breeding. That layered lineage finishes flowering in a brisk 8 weeks, a relatively fast timeline that gives growers a quicker turnaround than many indica-leaning strains typically require. THC reaches up to around 24 percent, a genuinely strong reading that lines up with the OG name's long-standing reputation for potency across countless descendant crosses. As an indica, it fits the shorter, denser growth structure typical of that side of the cannabis family, a habit well suited to gardens with more limited vertical space. Between its unusual three-way lineage, quick flowering window, and strong THC ceiling, London OG stands as one of the more distinctive indica releases in Holy Smoke Seeds' catalogue.
