Headband Diesel sounds amazing, I really want to try some out. Headband is a cross between Diesel and a Super Skunk x Sensi Northern Lights. Diesel and Northern Lights are Indicas and Super Skunk is a sativa, so Headband is mostly Indica. There are a few major differences between sativas and indicas. Pure Sativas refer to plants that grow in areas of the world with longer and hotter growing seasons such as Southeast Asia, Africa and South America. Sativas provide a clearer, creative, sometimes motivational, more cerebral high than Indicas. The most well known Pure Indica varieties come from Central Asia and the Middle East and were originally bred for hashish cultivation. Indicas have a more couch-lock effect on people. I like to say that when I smoke sativas I am high and when I smoke Indicas I am stoned. The one thing is that Sativas take much longer to mature and finish flowering and therefore there are very few pure sativas left. Indica plants are easier to grow and mature faster so commercial growers prefer them obviously. Hope that helps.
