I'll refer to plants that stem from the original cross as "classic", and those that stem from the [[Exotica Plants]] remake as 'Exotica'. Each has its own dedicated page below.
As of 2026, I haven't seen any remaining x rokko clones that are male -- all seem to be female, regardless of grex.
Plants from both grexes are exceptionally vigorous, well suited for indoor growing without a grow tent, and fairly free flowering. In my limited experience, I think the original cross flowers more readily than the Exotica remake. It is also a more flexible plant -- the EP remake is more robust, has larger dimensions overall, and thicker, more rigid stems.
