Critical Purple Auto Sativa or Indica?

Critical Purple Autoflower leans heavily on the indica side, featuring a blend of 80% Indica, 10% Sativa, and 10% Ruderalis. This genetic structure gives the strain its soothing, full-body high that’s perfect for winding down after a long day. Although it has a slight sativa influence, its primary use is for nighttime relaxation and sleep support. Expect a calming, euphoric ride that gently lulls you into a blissful, restful state.
