physical traits taste and smell are easy..they are visibly in our facewho know enough about the plant to actually look for specific traits that haven't been fucked up by somebody else.
its to actually know what trait from the high you want that seems to be lost on some..
ie."this weed is 32 % thc smells like fuel /gas ,gets big buds and is covered in resin"
its not near enough of the right info for me and a lot of the potentially wrong..but I am old..
for me ts about the type of high FIRST.
THEN..how much of it?
and I doubt I am gonna find it in modern weed
