great question TREE KING and i would love to answer it..but I can't I finally have popped my ISSxCTS which is supposed to be even more of a sativa then just the plain ISS..but from what i have read and all the smoke reports over the years..I have gathered that the ISS is a fruity,skunky, 1 hitter quit'er ..so from those descriptions I assume it's gotta be awesome...btw I plan to make some beans crossing the ISS with the ISSxCTS which i have both of..just need more time dammit lol..
peace

ISS is a nice plant,sativa tendencies and 2 extra weeks,gives out a feeling of awareness as it grows,you know what i mean kind of like its more awake than the rest of the plants,very goo yielder,likes full sun and plenty of food too.
The buzz is nice and irie,sativa high,but very conquerable after a while without any freakiness in the frequencies of the high,i personally like a Haze or colombian better.
My 2 cents
