M<\/span>aster cannabis cultivator Ed Rosenthal is in a state of constant experimentation. Within his office there is a blue jar with an electronic top measuring the precise humidity levels inside. The Miron glass jar is a deep midnight blue, designed to eliminate most light from passing through, and has a note taped to the outside that reads \u201cTest: Do not open.\u201d The jar is just one of the many trials Rosenthal is conducting as a part of research for his newest book release \u201cMarijuana Harvest,\u201d and inside there is a tomato that he keeps for months to assess the freshness of the produce. It\u2019s all part of the process to write the chapter on curing cannabis, a step that\u2019s \u201cessential to the taste and experience of the finished buds.\u201d<\/p>\n \u201cLike aged wines, well-cured buds are smooth and flavorful,\u201d the book explains. \u201cUncured buds still \u2018work\u2019 but are not nearly as enjoyable or desirable. However, curing does not make buds more potent than they already are.\u201d<\/p>\n \u201cMarijuana Harvest,\u201d<\/a> co-authored by San Francisco Chronicle Cannabis Editor and former Cannabis Now Senior Editor David Downs<\/a>, is the latest offering in a long legacy of cultivation books released by Rosenthal. And although the \u201cguru of ganja\u201d has been publicly pushing for homegrown backyard cannabis since the late \u201970s, arrives at an optimal time when more Americans than ever before have the ability to grow and cultivate marijuana for medical and personal use. The book offers techniques design to increase the quality and yield of homegrown flowers and pulls from years of research, controlled experiments and interviews with cannabis cultivators on what has worked so far. The methods inside aren\u2019t completely original, but rather, have been distilled in a way that highlights cannabis\u2019 accelerated development in modern crop science and draws from innovations in other agricultural industries to apply them towards growing marijuana.<\/p>\n \u201cWe are at the dawn of cannabis as a modern crop science,\u201d Downs writes in the book\u2019s introduction. \u201cArticles are being published in agronomy and chemistry journals and soon, we\u2019ll see entire journals devoted to cannabis and, eventually, libraries of it at places like the University of California Davis<\/a>.\u201d<\/p>\n To research the book, the two authors traveled to grow rooms across the country asking questions and compiling the knowledge and tools used to cultivate cannabis as well as other farmed crops.<\/p>\n \u201cAnd we combined that field reporting with what Ed does best: fearlessly question and innovate,\u201d Downs writes. \u201cWhat\u2019s impressed me the most about working with Ed is his daringness to hypnotize, and his egolessness when it comes to discarding disproven ideas. It\u2019s the difference between the expert, and the genius \u2014 that drive to relentlessly question and propose a new way of doing things. The fortitude to potentially be wrong, and indeed, see progress in failure\u2026 It strikes me that Ed was \u2018failing fast\u2019 decades before it was a Silcon Valley mantra.\u201d<\/p>\n For my own minor contribution to \u201cMarijuana Harvest,\u201d I joined Rosenthal and Cannabis Now Staff Writer Jimi Devine<\/a> in the lounge area at the Cannabis Buyer\u2019s Club Berkeley<\/a>, more commonly known as CBCB, to test a device with the potential to detect the moisture levels in buds and concentrates. Knowing the humidity present in the buds gives an indication as to how long one should dry cannabis before sale. After all, the value of premium nug is measured in its weight and potency and if the moisture levels inside all those mouth-watering dank trichomes could be easily ascertained, it could make things much easier for growers to judge when their flowers are ready to be enjoyed. In order to conduct the experiment Rosenthal brought along an electronic moisture meter, equipment that a building contractor would use to detect the moisture levels with the wall of a building. Rosenthal is testing whether this tech can be used on cannabis and I\u2019ve come along for my hand modeling skills.<\/p>\n Through the experiment, in which I pressed test buds and concentrates provided by CBCB onto the back of the meter, we discovered together that moisture levels in the fingers could affect the reading and we began to use plastic, glass and metal plates to separate the sample from my fingers.<\/p>\n \u201cIn the cannabis community there has been a widespread opinion that 12 percent moisture is a good content of water for smoking in a joint that won\u2019t go out and is also the percentage at which small sticks snap,\u201d Rosenthal writes, explaining that the meter should optimally read around this percentage.<\/p>\n Drying cannabis ends at 14-15 percent moisture, but a pleasant smoke is found around that 12 percent sweet spot. The book explains that cannabis becomes harsh and dry when moisture levels read at around 10 percent.<\/p>\n \u201cMarijuana Harvest\u201d is designed to teach marijuana growers of all scales \u201chow to avoid making costly mistakes, identify problems and solve them quickly\u201d and is full of options to jump in on the fun of developing the science around the world\u2019s favorite flower with further personal innovation.<\/p>\n \u201cExperiment and find what works for you.\u201d<\/p>\n TELL US, <\/strong>have you ever grown cannabis?<\/p>\n The post Book Review: \u2018Marijuana Harvest\u2019 Helps Cultivators Hone in on the Craft<\/a> appeared first on Cannabis Now<\/a>.<\/p>\n
