What’s the Difference Between Cannabis & Industrial Hemp?

Im currently growing 3 female industrial hemp plants. the seed is from a wild plant in an old hemp farming area. it definitely is not low potency, the resin gland are many and the calyxes are fattening nicely. I believe that the only difference between hemp and cannabis is care for the plant and growing conditions. ie. separating males, proper spacing/fertilizing etc.
