The ideal moisture content for dry trimming cannabis is around 10-12%. At this moisture level, the buds are dry enough to be easily handled and trimmed without sticking to the blades or becoming too brittle, but still moist enough to prevent excessive damage to the trichomes during the trimming process. It's important to note that the ideal moisture content for dry trimming can vary depending on the specific strains of cannabis and growing conditions. Therefore, it's a good idea to monitor the moisture content of the buds regularly during the drying process using a hygrometer, which measures the relative humidity of the air in the drying room. By maintaining the ideal moisture content for dry trimming, you can achieve the best possible trim and preserve the quality of your dried harvest.
