Stem Rub

๐ŸŒฟ Cultivation First mentioned: Ep. 051

A technique for evaluating cannabis phenotypes early in the vegetative growth stage by rubbing the plant's stem between the fingers and smelling the resulting aroma. The volatile compounds released from stem trichomes give breeders an early indicator of the plant's terpene profile before flowering.

Discussed in Ep 051 as a practical tool for breeders and pheno-hunters. Allows growers to narrow down large populations of seedlings before investing the time and resources of a full flowering cycle. Panelists emphasized its value for selecting mother plants and identifying keeper phenotypes from seed runs.
