Ed Rosenthal

We all know Ed Rosenthal. Or should i say you shld know Ed if you have ever tried to grow weed. In the early times of marijuana growing many people simply grew very large plants and ground up the plant matter and smoked it. In 1976 Ed Rosenthal and Mel Frank published ‘The marijuana growers handbook’ and the light cycle as we know it today developed. Pre Rosenthal and Frank those who grew outdoors had a little surprise ready for them around September/October. Those who grew inside were blessed with harsh, unpleasant smoke of the stalk and leaves. As the 18/6 and 12/12 light cycle developed we see the increase of quality bud.
