FOREWORD by TOMMY CHONG
ll my close friends are pot heads! And one of my close friends is not only a pot head he is the expert pot grower who holds the distinction of turning more people on to pot than Cheech and Chong. I am talking about Ed Rosenthal, the pot-growing gardener whose Ask Ed column has helped keep the DEA busy chasing down the few hundred thousand or so pot gardens currently growing all over America. And not only is Ed a great gardener, he is also a great revolutionary, an “anti-establishment” hippie who likes to wear weird clothes and “out” the corrupt Federal officials who insist on enforcing America’s sadly outdated drug laws. When I first met Ed, he was facing 10 years in Federal prison for doing pretty much what he has been doing for the past 30 or so years— growing pot. The Feds insisted Ed broke the law, and Ed would agree with them—and then explain,“It’s a terrible law!” Ed is also a writer of books, an occupation I have just recently been exposed to. Ed’s books are treated pretty much like the “pot bible” when it comes to combatting disease, thieves, and other pests that could waste an entire growing cycle. This is another reason why I admire and respect this man. Writing is hard; comedy is easy. Writing is like masturbating when you have just masturbated. It’s not fun. But it has to be done, or else people would not have anything to read while they sit on the toilet. Now, notice how I headed right into the toilet when I called myself a writer? There must be a reason for that, eh? No, I am being modest about my talent as a writer but for good reasons, on the other hand, however (now I just made, what, three mistakes in this last sentence?), Ed is a writer. He is an excellent writer of how to do anything concerning pot. How to grow it. How to hide it. How to care for it. How to smoke it. How to stay out of jail while growing it. What to do while you are in jail for growing it. Ed has the whole field covered. Ask Ed. And I do on occasion ask Ed. I ask him why he thinks pot has stayed illegal for so long. His was an interesting answer. A really surprising answer. And an intelligent answer. One I cannot divulge for reasons…well, to tell you the truth…I don’t remember his answer because I was smoking at the time we had that conversation, and you know us pot heads! I’ll remember the answer right after I stop writing this…whatever it is I am writing.

Anyway, Ed is probably one of the most intelligent men I know, and he does have the answer to quite a few problems facing Americans today. So, if you have the time and the inclination, check out Ed’s writings. Read what he has to say. You may not be ready for him, but you are not alone. Even the United States Government had to back off when it came to arguing with Ed. They did back off, and I have to say that when the pot laws change and disappear, we all will have to take a moment before we light up that legal joint and say a silent, “Thanks, Ed Rosenthal,” because he stood in front of the government tank and faced it down. And he was totally zonked out of his mind when he did it. Thank you, Ed— Tommy Chong

by R. KEITH STROUP, ESQ.
d Rosenthal, the best-known marijuana horticulturist in America, and the expert relied on by hundreds of thousands of marijuana growers when they want to learn the best marijuana cultivation techniques, is a friend and colleague whom I’ve known since the 1980s and ‘90s, when he wrote a monthly cultivation column, “Ask Ed,” for High Times magazine. We have, over the years, at times disagreed over style and tactics, but I have learned to appreciate Ed’s significant contribution to the movement to legalize marijuana in this country. He has been a leader in bringing the best cultivation techniques to a mass audience, and he has shown the political courage to stand up to the full force of the federal government, and lived to tell about it. As Americans first began to grow much of our own marijuana here at home—some with the goal of saving money, some to assure a high-quality product, and others to avoid dealing with the underground market—Ed clearly had a very positive impact on that movement. Any home gardener knows that although anyone can learn to be a successful grower, whether they grow vegetables, flowers, or herbs such as marijuana, gardening is not as simple as planting a seed and watering it occasionally. It requires a lot of expertise that generally can only be gained from a good book or a more experienced friend. Ed has long been providing accurate and detailed instructions to wannabe farmers so they could turn a good intention into a good crop. And he continues to provide that expertise today, with the publication of the 25th anniversary edition of The Marijuana Grower’s Handbook. Personal cultivation is crucial. It protects consumers from the possibility, once marijuana is legalized, that big corporations take over the market. Tobacco companies, for instance, already have the land and processing plants available—but the marijuana they may offer could...
