In the '70's the best Colombian weed was Amarillo (spanish for yellow). It was a deep yellow color, sticky, aromatic, and psychedelic af. The same plants could ripen green or yellow depending on environmental factors (rain at the right time, dry heat at the right time). When weather and genetics cooperated to produce a crop of Amarillo it was a special occasion. In my youth I had the privilege of sleeping on a boatload of it for 11 days, all the way from Parque Tayrona to Shelter Island, NY. Maybe you figured out how to duplicate it.
