Gardeners who romance the bud know that the leaves, the natural by-product of their work, present an interesting paradox. It is bud with perhaps 5% THC that is typically the focus of their obsession. Commercially this jewel is valued by consumers and it sells for several thousand dollars a pound. The fan leaves, which contains 1% or more THC but provide a much harsher smoke, are often thrown away by these connoisseurs, and has a very small commercial value. Trim, which contains 2% or more THC, commands only a little more respect, and is also moderately priced.
Mature marijuana plants typically yield half as much or more leaf as bud by weight. The result is that 10-15% of the plant�s total THC production is often thrown away. Most gardeners have been content to sacrifice these glands to poor relatives, high bakers or the trash. Recently, Milla�s �Pollinator� has regenerated interest in a solution to the leaf conundrum. A few years ago, the late John Gallardin developed the Sifter and Master Sifter. Both of these devices are based on the silkscreen used worldwide.
