Entire countries are adopting similar measures. The medical legitimacy of cannabis has emerged out of its modern Dark Age. For the first time in history, pharmaceutical companies in Europe, and hemp oil factories in Kentucky are growing strains that are numbered, not named.

We are at the dawn of cannabis as a modern crop science. What follows in this book is the third draft of that science. Cannabis cultivation—and harvesting in particular—is evolving from a folk art to an agricultural field. Hundreds of papers are waiting to be written about topics like optimal terpene preservation and chemical changes associated with flushing.

In writing this book, we studied prior research, conducted controlled experiments, communicated with researchers and went all over the country interviewing cultivators and working to systematize that knowledge. They let us into their nurseries, their veg rooms, their bloom rooms. We asked questions: What mistakes did they make along the way? Where do they want to take their craft? And we combined that field reporting with what Ed does best: fearlessly question and innovate.

The fortitude to potentially be wrong, and indeed, see progress in failure. This type of relentless innovation is important. Commercial growers are going to have to never stop optimizing and that dynamic will only benefit consumers. Please enjoy, Marijuana Harvest. After all—the thing about science is advancing knowledge. Each contributes to the final quality of the flowers. A good crop followed by a poor harvest is as disastrous as crop failure. The goal of this book is to preserve and even improve the quality of your crop by showing you how to pick, cure and prepare your flowers and leaves for a variety of uses.

Growers usually plan their gardens in great detail by setting timetables and cultivation parameters for their plants and bringing the plants to the peak of maturity. However, they often spend a lot less time planning the harvest.

Even large commercial operations are sometimes far behind in harvest and post-harvest operations. With proper preparation the process can flow seamlessly. Whether you are a sole practitioner or putting together a harvest team, try to divide up the tasks so there are few bottlenecks. The task flow can be divided in many ways. For instance, if a grower has access to an area to store branches or colas but insufficient trimming facilities, they ought to prioritize bringing in the buds and pulling off fan leaves.

The colas can be placed in storage to dry before trimming or under refrigeration to keep them fresh for wet trimming. Then the material can be manicured over a longer period of time. Make sure to prepare for each stage. In many cases, even on large farms, not much has changed over the years. Growers tend to get set in their ways; their gardens are easily dated by the techniques they employ.

Not all growers realize new equipment is available to increase efficiency and cut down on the manual labor associated with the harvest. Proper harvesting includes keeping the buds clean and fresh and preserving flavors and aromas. For this reason, at no time during the drying and curing process should the temperature be raised very much above this point.

Before it is consumed, marijuana is judged first by appearance and then by smell. Fresh, aromatic buds are the most likely to be demanded and consumed. This book will show you the best methods and latest technologies not only to properly harvest your marijuana garden, but also to finish the job right.

It consists of multiple processes done in a specific order: cutting down plants, their colas or buds, removing their leaves, then drying, curing and storing for later use or for processing into buds, extracts, edibles and other products. Even a small harvest requires a little bit of labor.

Processing a large one adds complexity and requires planning. Determining when to cut the crop, whether to cut whole plants or to judge each bud for its ripeness, when to trim, how and where to dry and cure the buds for use or processing, how to preserve the aroma and taste by retaining the terpenes and essential oils, are important decisions for any harvest.

If the plant is small, it is more likely that all the buds will ripen at the same time. On larger plants, the outermost exposed parts of the buds, the first inches 7.

Another consideration is that different varieties have unique ripening patterns. Buds ripen from the top down on some varieties, and all at once on other varieties. Consider that in a garden of mixed varieties the ripening times may vary by several weeks. Small gardens with a yield of ten pounds 4. Growers with larger yields, especially those that ripen over a short period of time, require more elaborate preparations. Indoors, where plants are harvested on a weekly or monthly basis, harvesting becomes a routine task.

Cannabis is a fast-growing annual plant that does best in well-drained, high-nutrient growth mediums and long periods of bright, unobstructed light. The plant starts out as a small oval brown seed and usually grows vegetatively for several months before starting reproductive growth or flowering. It begins flowering when it receives at least nine to eleven hours of uninterrupted darkness, depending on the variety, each hour period.
