Wookie Pie: This Wookies X Grape Pie cross is an indica dominant hybrid. These dense, purple buds have purple calyxes with a classic musk mixed with fruity spice and gas. Rosin is a cannabis concentrate that is solventless—it’s not made with any solvents or chemicals. Relying on heat and pressure to extract cannabis compounds, rosin is considered a cleaner extract. Cannabis plant material is placed in a press with heated pads and then compressed, squeezing out hot oil.
