A lot of it is your personal preference... All of Sub's seeds I've grown out so far (JTR, Pandora's Box, querkle, Agent O, Chernobyl, (2 Vortex pick and mix males)).
My choice after smoking a female of all the above strains was Chernobyl. I have kept only Chernobyl in my garden for about 2 years. It has ZERO ceiling, but has caused lotsa friends to sweat, get a little pale, and usually pass out after being blasted high for a couple hours!
tastes like limes and sour grape skittles. plus mine turns very purple almost black and red too!
But I have been smoking for about 4 years daily. two of which have been solely Chernobyl.... some think I'm crazy but I mean Trainwreck plus JTR you are sure to get sufficiently medicated
