I have been growing a Sumatran strain for over 30 years. A reliable Indonesian friend sourced the seeds for me ex Aceh early 80's. I have managed to get it back to a managable size and with very quick bud development. Typically 2m and late Feb/Early March in southern mediterranean climate. Once the flowers start, they build very very quickly indeed. Left alone it attains a very pretty xmas tree shape with fewer head leaves. Great for the manicure. Leaves are nicely serrated, deep green with red/purple leaf stems. On the bush the flowers have a nice heady sweet floral fragrance. Currently in the process of crossing with some renowned US and Euro imported strains to boost potency and create faster finishing improved potency pheno. As a guerilla outdoor enthusiest, by design its a long slow process. Current appalling legal status also makes it a difficult hobby. I travelled extensively thru Indonesia in late 70's and the product varied from goddam awful to extraordinary. Way befor my enthusiest days, so the genetic opportunities passed me by. I like to think I'm making up for my lack of vision now. Be good to hear from a few other antippodean (or other) gardeners. Peace.
