Flushing a hydroponic system removes salt precipitates and other debris from the growth medium, pump and lines, and is also helpful as a way of washing the excess salts out of your plants. You may want to do this before harvesting, to improve the flavor of your crops, or as routine maintenance every time you replace the nutrient solution. From time to time, flushing may be necessary to save your garden, but usually it is optional and is only required if the plants show signs of distress. Drain the nutrient reservoir, using the technique most appropriate to your particular system.

Pour the old liquid on your outdoor garden, trees or bushes to give them a boost.

Clean the nutrient reservoir, removing any sediment or algae that might be present. Use a plastic scraper to scrape algae off the sides, if necessary, and rinse everything out of the tank. Fill the tank with plain water and pump it through the system. Add an optional flushing agent to make the process quicker and more effective.

Discard the flush water and refill the system with plain water, with or without the flushing agent, per label directions.

Test the pH of the water, and use drops from a pH adjusting kit as necessary to adjust the pH of the new water to about 6. Set the system to operate normally and let it run for 24 hours. Toss the flush water again, and refill the system with fresh nutrient solution.

Digital Vision. This removes any buildup of nutrients in the plants that could make your harvest taste bitter and gets your system ready for the next round of plants. Flushing your hydroponic system every other time you change your nutrient solution is typically adequate to keep both your system and your plants in top shape. If your system is clogged with a lot of dirt, minerals or other debris, you may need to flush it several times to get it clean.

Warning Plants that develop brown spots or curled leaves may be suffering the effects of salt toxicity, a condition in which the plants have a buildup of salts on the roots and can no longer absorb nutrients properly.

The system must be flushed immediately if the plants are to survive. Typically the plants will need several days of plain water before the excess salts are gone and it is safe to use nutrients again.

Classical methods for growing cannabis in soil call for cultivators to administer three essential nutrients, nitrogen, phosphorus and potassium, or NPKto bolster the vigorous growth and yield of their cannabis plants.

This is where flushing comes into play. Simply put, flushing is the process of watering your plants without any added nutrients in order to expel chemical buildup from within the plant tissue.

This course essentially forces plants to absorb and process excess nutrients without storing any unnecessary minerals. Something to keep in mind when flushing, is to optimize the pH of your water. The results of an unflushed plant are most noticeable during smoking.

Additionally, the flower may be extra difficult to burn, resulting in unneeded frustration on behalf of the consumer. When flushing, you want to make sure you administer enough water to hold the nutrients and flush them out.

This may require watering the plant once, waiting a few minutes, then adding more water until it flows clear out of the growing vessel. Finding the right moment to start flushing your plants is contingent on your growing method and how close the crop is to harvest.

When growing in soil, cultivators should consider flushing about two weeks before harvesting, toward the end of the growth cycle, when trichomes begin to form a cloudy white color. Unlike soil growing, however, hydroponics only require a few days of flushing to get the job done. Another fault of flushing too early is the increased proliferation of yellowing or discolored leaves that give the plant an unsightly look. Flushing is not a perfect process. Growing is a variable process, one that is altered by many factors, including, but not limited to flushing.

In cases where extreme, toxic levels of nutrients are administered to a plant, the negative manifestations of not flushing can be severe.

In cases of consistently grown hydroponic crops, that received appropriate concentrations of these elements throughout their lifespan, failure to flush will be less noticeable. Whether you are growing hydroponically or in soil, flushing is an omnipresent technique in mainstream cannabis cultivationthat airs on the side of caution. The only way to really find out yourself if flushing makes a difference is to conduct a controlled experiment of your own.

A good technique is to grow two clones of the same cannabis strain simultaneously under the exact same conditions.By accessing this site, you accept the Terms of Use and Privacy Policy.

Although visions of frantically trying to shove a cannabis plant down a toilet may come to mind, flushing is actually when you stop feeding the plants nutrients and simply give them water.

The process is generally as easy at it sounds; however, knowing precisely when to flush and how often is a more refined skill. Cannabis plants have different nutrient needs throughout different stages of growth; what it needs in its vegetative stage is different than what it needs while flowering. Think of it as someone changing their diet.

You can fill your fridge with new types of food, but you might find yourself running out of room if you never removed the old food.

By removing the old food, you are clearing a path and starting anew. Overfeeding cannabis, improper pH levels, and other stresses on your plants can result in a nutrient lockout. This will allow your garden to resume absorbing nutrients and grow at a healthy, successful rate. Your final flush should occur before harvest. This will force the plant to use the nutrients stored within itself in the final week or so. Once again, flushing cannabis simply involves running pure water though the soil or medium.

When trying to stop a nutrient lockout or when switching nutrients, perform a flush by excessively watering your plants with water that has a pH level between 5.

Fully saturate your pots, and repeat 15 minutes later. The flush should clear any blockage and make room for your new feeding schedule. To be certain a flush was successful, you can use a TDS total dissolved solids reader to determine how pure the water runoff is. You want the TDS reading of the water draining out of the pot to be close to the TDS reading of the pure water you are flushing with.

This reading will ensure that the nutrients have been washed out of the soil. When looking to perform a flush before harvest, there are more factors to consider. Make sure your plants will be ready for harvest once the flush is complete.


Flushing too early or too late will result in a lower-quality product. If flushing two weeks prior to harvest, you should begin when you start seeing the first trichomes turn milky. The only time flushing is not encouraged is when you are growing in amended organic soil. This is because your soil already holds all the nutrients the plants need to thrive.

Furthermore, these plants almost always receive pure water during waterings.Forums New posts Search forums. What's new New posts New profile posts Latest activity.

Thats Just My Opinion Though. I would think it also matters, because that water will also remain in the pot, until dried out. Unless you plan on flushing again with the new nute'd water seems kinda a waste. You must log in or register to reply here.What if there was one thing you could do right before you harvest, and no matter the strain, medium or nutrients you were using, this one thing would greatly increase the quality and size of your yields? Flushing is the process right before you harvest of trying to flush out all the excess salts, nutrients and other contaminants that build up in your plants.

The way that most growers flush their plants is by giving them plain water with no nutrients for a set period of time. Flushing is a free and easy way to increase the quality of your final harvest. Here are just a few of the reported benefits of flushing your plants: Can improve the smoothness of the final product and reduce harshness Can help remove any chemical tastes from the final product Increased terpenoid production from the slight stress of no nutrients Increased final bud swell during the final days before harvest.

By getting rid of excess nutrients left over from the growing process, you improve the smoothness of the final product. So the bottom line is that most growers flush to improve the potency, taste, aroma, size and overall quality of their final harvest. Here are some quick guidelines: Soil growers should flush the longestat 1—2 weeks. If you flush your plants too early, you can reduce yields and potency.

The best way to see if your plants are ripe and ready for harvest is to look at their glandular stalked trichomes a. These trichomes look like crystals or frost on well-cultivated buds. Trichomes change color as they ripen. They start clear, then turn translucent or milky white and finally they turn an amber color. And when you flush with plain water, you really are only relying on the water and essentially washing the plant, root system, and growing medium to remove those excesses.

Instead of flushing with plain water, which starves your plants and reduces floral growth and resin, you need Flawless Finish. It uses a broad range of empty chelates — which are like tiny, powerful vacuum cleaners — to remove excess chemical residues from your growing medium, roots and other plant tissues, including fruits and flowers.

This is because there are many individual metals that need to be pulled out of crops.

Chelates come in different shapes and sizes and are attracted only to certain metals. When you use Flawless Finish, the end result — as proven by scientific testing — is a stellar crop of plants that will be free of at least 85 percent of the stored materials they held before flushing.

Although flushing water lines between flocks is recommended, flushing cannot always remove the slime layer or bio-film of bacteria or algae. Therefore, more poultry growers are incorporating some form of organic acids to their water-system flushing procedures. In addition to suppress bio-film formation in the water lines, this procedure will reduce harmful bacteria, improve animal performance as well as food safety.

From feed formulation to delivery, great attention has been paid to the feed your bird receives. Poultry nutritionists have fine-tuned their feed formulations based on years of research and how this research performs in the field.

Feed manufacturers place great importance on feed and pellet quality while ingredient purchasers set strict standards to assure consistent ingredients are purchased every time. Poultry producers maintain secure storage facilities to protect the quality of the feed delivered to their birds.

Although feed quality has received much attention, the quality of the water that birds drink is often overlooked. Substandard water quality — water contaminated with microorganisms, algae, dust, and rust -- is relatively common and can have a profound adverse impact on poultry performance.

In some aspects, water quality can have a greater negative effect on bird performance than feed quality because it is a well known fact that birds consume more water than they consume feed.

According to several studies, more than 40 percent of privately owned individual drinking water supplies — typically found on U.

In some regions of the world, more than 70 percent of the water supplies are contaminated with coliform bacteria.

The microorganisms can enter a water supply from a variety of sources including sewage, animal wastes, or dead animals. Although some of the microorganisms found in the drinking water can be potentially harmful, others are not. For example, iron bacteria are a major nuisance in many well-water supplies.

Iron bacteria should not be confused with iron dissolved in water that causes red water and stains on clothing and plumbing fixtures. Iron bacteria do not cause disease, but do form a reddish-brown slime that coats the inside of pipes, fouls pumps, and clogs waterers. All of which represent a major challenges for poultry growers.

Algae are another type of microorganism that contaminates poultry water supplies. Some algae produce compounds which are toxic to poultry. In addition, some non-pathogenic bacteria and algae impart an offensive odor or taste to the water, which in turn results in water refusal, leading to a drop in feed intake and poor bird performance.

A major contributing factor to the presence and intensity of bacteria or algae contamination in poultry drinking water is the amount of dissolved nutrients — specifically phosphorus and nitrogen -- in the water.

These nutrients facilitate the growth of bacteria and algae through a biological process known as eutrophication. In a major study conducted several years ago by the U. Geological Service at the Massachusetts Military Reservation near Cape Cod, researchers concluded that the phosphorus was a common cause of eutrophication.

Over time, eutrophication can progress to a point where the bacteria or algae form a visible slime layer — or bio-film -- on the inside surface of water pipes. Poultry growers find that water-borne bacteria and algae are difficult to kill. The cells of these microorganisms are encased in a cell wall. Common disinfectants and sanitizers cannot penetrate or degrade the cell wall. Bio-films provide bacteria and algae with additional protection from chemical assaults. Pat Welch, a poultry production consultant, says.

The aim of a water-system shock treatment is to expose all interior surfaces of the drinking water system to a sanitizing agent for a sufficient period of time to reduce the surface tension of the bio-film and dissolve mineral deposits that have accumulated in the water lines, and kill potential vegetative bacteria and algae growing in the bio-film. Welch cautions poultry growers to exercise care when mixing acids organic or inorganic and detergents with chlorine products due to the release of chlorine gas which can be harmful if exposed to the eyes or upper respiratory tract.

Welch advises poultry growers to don personal protective equipment before using oxidizers to shock water lines.

Also, some oxidizers used for shocking water-lines are caustic and cause chemical burns on exposed skin or mucous membranes.
