About this release

Information on Zourgum Zourgum is a feminized limited-edition variety from T.H. Seeds that revives the original Bubblegum and blends it with modern elite clones. Created in collaboration with Hall of Flame, it’s a unique series available only while stocks last, aimed at growers who value flavor, exclusivity, and flowers with strong visual appeal. Now available at Alchimia. Genetics and origin of Zourgum This cross combines Zours (a Runtz x Sour Diesel hybrid from Hall of Flame’s private selections) with T.H. Seeds’ Original Bubblegum, a stabilized IBL introduced by the seed bank in 1993. The outcome is a balanced 50% indica plant that carries the sour, award-winning terpenes from Zours alongside the classic Bubblegum sweetness. The fusion of new-school vigor and stabilized heritage defines its particularly distinctive character. Growing Zourgum indoors and outdoors Zourgum grows slowly during the vegetative phase, then stretches in height and width at the start of flowering, forming a dense, highly productive structure that typically reaches 120–160 cm. Flowering takes around 9–10 weeks, delivering notable indoor yields of 450–700 g/m². Outdoor harvests can reach about 600 g per plant under optimal conditions. It’s not the simplest choice for beginners—its gentle vegetative start calls for patience and some pruning. It responds very well to one or two toppings to encourage lateral branching and maximize yield, and it adapts to different growing media. A signature trait is its dark, almost black coloration with pink streaks that emerge late in bloom, a result of high anthocyanin content. Aromas, flavors and effects of Zourgum On the nose and palate, Zourgum leans into pronounced sour-candy notes over a fruity, sweet base that clearly recalls its Bubblegum lineage, with hints of strawberry bubblegum and earthy, gassy undertones for added complexity. It’s intensely aromatic and preserves terpenes very well during drying and curing, making it an appealing candidate for
