it would be really really hard to determine a starin without knowing where u gt the seed/clone from,
is there noway u can trace it back to find out the strain, whoeva u gt the seed/clones from do they not know and if its bag seed can u nt ask ur supplier wat strain he was sellin or wateva.
a strain is the genetics of a plant wen two different strains or types of plant are bread together they create a new strain, kinder like horse breeding ppl looking to get the best features from a certain plant and leaving the bad features behind.
i.e. a cheese female bread with a male blueberry creates bluecheese.
