I am coming close to harvesting my first plant and have been doing a little research along the way. I understand sativa strains=heady high, indica strains=couchlock high. I have been reading that when trichomes are cloudy this= heady high, when trichomes are amber this= couchlock, and 50/50 is a mix. If this is the case, when it comes to the type of buzz one wants, what is the point in picking a sativa or indica strain if it seems this can be manipulated during one's grow?
