Growing epic pot

Ok what techniques when growing separate the average homegrown bud to the epic, tricome covered bud u only see on the web or if ur lucky you can grow it. How would a person go aboutbdrastically improving the potency of their homegrown buds?

genetics is the biggest factor, get some pro seeds. BC GOD is the dankest most "epic" strain ive ever smoked, i think its what you want

a close second is care and knowledge of the plant

Well like what about nutrients and stuff like that?
