Flushing, especially pre-harvest flushing, is as fiercely debated as anything in the cannabis cultivation industry. One side is rallied against the idea of flushing before harvest, insisting it doesn’t perform well. The other side will valiantly fight for flushing. They’ll bark incessantly that a fortnight of flushing is the only acceptable method for growing tasty, highly smokable marijuana. Perhaps they’re both right. Perhaps flushing is great for those who know how to utilize the power and is a detriment when it falls into the wrong, incapable hands. It’s like the ancient philosophical question: do nutrients have a flavor? If you find yourself in the pro-flushing category, like the American standard, there’s no doubt you’ll enjoy this list of flushing do’s and flushing don’ts. Do: Use clean, balanced water. Chemical cleaners and flushing products seem to invalidate the idea of flushing. If the purpose is to remove excess chemicals and nutrients, then adding more chemicals or nutrients is counterproductive. Avoid adding anything but water throughout the process. Don’t: Overwater. Overwatering plants can happen at any time in the plant’s life cycle and is a prime culprit for the destruction of most novice gardens. A pre-harvest flush is no different, though the idea of pouring gallons of water onto your plant may seem an easy cleansing tactic, it must be done properly. Do: Flush for at least a week. Chemical and nutrient buildup, like arterial buildup, can’t be flooded through the plant’s system in less time. Many growers advocate a week and a half to two weeks of flushing to assure your plant a crisp, authentic flavor. Don’t: Utilize a pre-harvest flush as a fix-it-all for overfeeding. Some assume, with a proper flush, all their chemical errors along the way will simply wash away. This is not the case, and sometimes even flushed plants can leave a chemical aftertaste and dark ash. Do: Flush if you are switching nutrients. A pre-harvest flush isn’t the only recommended route. If you plan on switching nutrient combination or nutrient brands, it may be best to do a short flush before making the leap. This will help the plant “digest” the nutrients fully before new ones are added. Don’t: Rush the flush. Some growers I spoke with believe that rookie flushers should tread carefully and monitor their plants closely while flushing before harvest. Rushing the process can lead to drowned, unhappy plants and can ruin an entire crop. If you need water to cleanse your body, what makes you think a plant is any different?
