Many moons ago I grew out dr green thumbs big purps. A cleaned up land landrace from north India. To date, one of the best strains I've had in terms of unique effects and taste. I have old seeds that I made but am unable to germinate them. I contacted the doc on the off chance he might part with some.....wishful thinking on my behalf. Anyway, there must be some out there somewhere, someone might be still growing it? Or from peoples experience is there other varieties that are closely related
