curing its a delicate bacterial process with too many variables to make generalizations, chlorophyll, glucose, cellulose and other long carbon chains are decomposed as a result, in that aspect plant tissue its pretty much all the same across a wide range of related plants, meaning both sativa and indica are so related that the chemical composition of the plant itself (not resin) its pretty much the same thing. that being said a big fat hard dense nug will provide better conditions for anaerobic bacteria to thrive making them prone to mold but easier to keep in curing conditions than airy buds, also sativas evolved in moister hotter environment making them a bit more resistant to the bacterias and fungi involved in curing. so in my eyes its not really about time because you can cure quick at the edge of molding or long in a more oxygenated environment and both will result in very different final product. the consensus in the cannabis industry is that long curing without too many tissue getting destroyed is the optimal and most desired result. so indicas are easier to cure and sativas are harder to cure, this can sometimes result in a longer slower process when not done right
