Most of my growing was indoors, and I have grown a pure indica indoors, Hindu Kush. However, Sativas generally grow better outside because most indoor grows have height restrictions and/or light issues due to stretching. My only two outdoor grows were mostly experiments that went well, but I never got a chance to try growing a pure sativa like DP.
Growing sativa outdoors can be challenging for stealth growers because of how easily they are spotted, so again they get a bad rep. Sativas got the bad deal just because they are easily spotted and difficult to control imo.
Even growing something like Super Silver Haze was a challenge indoors because of the height issues. Indicas generally have a smaller height, making them more ideal for growing indoors or even for stealth growing.
CBD strains were just gaining popularity when I was growing so I never got a chance to see how those grow, but I did notice a certain smell CBD strains have. It's spicy or musky.
