That comes down to preference. I am a KUSH lover. I Like Indica and Indica heavy hybrids. I like growing Indica’s more becasue of their shorter heights and ease in growing. You are trying to chose between a Satiiva based strain and an Indica based strain. I cannot tell you one is better than the other but I prefer to grow my sativa’s outdoors becasue of their stretch. In a tent, I prefer auto strains. I would rather do 4-6 small auto flowering strains in a tent, have a wider variety and a product in 7-12 weeks. Photo plants take 5-7 or more weeks to veg and then an additional 8-10 weeks to complete their flower. The yield is substantially larger but I can grow 2 crops in that time and have a greater variety.
8’ tall tent is as tall as they get without a custom build. I have a 4 x 8 tent that is 6.5’ tall. With that size tent, I needed: Larger volume sir intake fan, more lights (I have 3 lights, waiting on my 4th, 3 bulbs (2 heat lamps, 1 red), a fan for circulation, a humidifier and an oxygenator (used intermittently). A starter tent is usually just enough to grow a couple/few plants. You can get by with a 4" intake fan and 1 decent full spectrum light, a fan. If you think you are serious about growing, go larger now or you have to re-invest and it is cheaper to go bigger than it is to replace with a larger environment
