Let’s look at what’s happening in the Hawaii project as an illustration. The issue in that case is one of adaptation. What we call “hemp” — or some prefer “industrial hemp” though I think “hemp” is just fine — is a breed of cannabis generally found in the temperate zones of the planet. The plant’s life cycle is driven by a genetically programmed response to the length of the night. Nights in the temperate zone begin to lengthen after summer solstice and the plants shift from vegetative growth — which has resulted in long stems — to reproductive phase, so seed will be set and matured by frost.

Where do all those different types come from? OK. School’s on.
