I try to replace Ape all the time! Either the strain doesn't purple up like it should, or it doesn't smell and taste as good as Ape, or a combination of the two.
I still haven't found a good replacement. I gotta have one purple, frosty bag appeal strain....and so far this one is the best I've found.
Tangie has about 3, maybe 4 weeks. I am starting to take it a bit earlier than I usually do, as the terps get more complex and "sour" when I let it go longer. They are very obviously citrus now and will stay that way for 3 more weeks at least.
BTW, the new drenches have improved terps on several strains. Are you using them now? If so, what are your thoughts?
