I've wondered about mixing buds from different grows but haven't because my stash is all hybrid anyway. I am growing a 100% sativa right now. I am planning to grow landrace cultivars and also try a 100% indica. I can see mixing the two together but haven't really considered at what percentage, i.e, 50/50 or some other ratio. It's hard for me to distinguish the subtleties of the hybrids that I've grown. The effects of the ratios of indica/sativa are not readily apparent to me unless it's closer to 'mostly' either an idica or a sativa. The last two grows were Killer A5 Haze and Super Lemon Haze, both high enough sativa cultivars that I can easily note the difference in the effects of the bud. So, looking forward to more experimentation.
