Flushing is an important step in the cultivation process of cannabis. When done correctly, it helps ensure a high-quality final product, free from potentially harmful residues and contaminants. In essence, flushing means removing fertilizer and salts from the growing medium before harvest. It is the process of eliminating the nutritional components that have been introduced to the cannabis plants throughout their lifecycle, allowing them to grow and thrive.
Cannabis is a very sensitive plant; when grown in soil or compost, nutrients must be present to support its growth. Similarly, it is important to feed the plant the correct amount of nutrients; too much can be just as detrimental as too little. To ensure this balance is met, when cannabis is grown outdoors, fertilizer may be applied to the soil twice a month. For indoor plants, more frequent fertilizer doses are usually recommended. As such, a considerable amount of nutrients will build up in the soil throughout the grow cycle; if not flushed, these resources can remain in the root zone and be absorbed by the plant’s buds at harvest, impacting the overall flavor, smell and appearance.
When flushing cannabis, growers can choose to either give their plants a deep water flush, or supplement flush. A deep water flush is the most common and best method of flushing, as it dissolves any residual salts and other build-ups in the soil. It is done by manually saturating the soil with plenty of water, being careful to maintain a slightly lower pH than usual. Before the water is removed again, nutrients will have been dissolved and flushed out of the growing medium.
Supplement flush is a more costly but equally effective method of flushing cannabis. It involves using a commercial rinsing product, such as hydrogen peroxide or other specialized flushing agents. Whatever flush product is used will be applied to the soil, whereupon the plant’s root system will absorb it. This will help to eliminate any build-ups of minerals and salts which have been taken up by the growing medium, thus preventing them from being responsible for an inferior-quality final product.
Flushing is of utmost importance to cannabis growers as if not done properly, it can lead to a lower-quality product, and in extreme cases, can even be dangerous to consume. Besides its direct influence on flavor, smell and yield, flushing is necessary to remove any build-up of fertilizer residues, which can otherwise contain potentially harmful contaminants that could harm consumers. Additionally, not flushing the plant can result in a bud’s color being compromised, as well as impacting its potency and aroma.
In summary, for optimum quality, flushing your cannabis plants prior to harvest is essential. When done correctly, it helps rid the plant of any potential contaminants present in the soil, allowing growers to produce a top-shelf product that consumers can enjoy with confidence.
