Flushing cannabis plants is essential to the cultivation process. You can make corrections to certain issues when you do a flush. If you flush before harvesting your crops, it will unlock the flavor of your buds. And this is important.
Now why would you do a flush? Well, the process of flushing will drench the growing medium that you used with water or you could apply flushing solution. And it doesn't matter if you grow your cannabis plants organically, outdoor or hydroponically. You will always need to flush.
The reason you flush is so the cannabis plants can absorb the additional nutrients within the soil. This will depend, though, on why have to flush or when you have to do so. Some cannabis growers will apply this technique if they notice any lockout signs of the nutrients or if the harvest is showing signs of over-fertilization. How is this process done?
The Process of Flushing Cannabis Plants
There are no special techniques or tools that are necessary to handle this procedure of flushing cannabis plants. Rather, you will have to feed your plants with nutrient solution. You use pure water to do so or use a flushing solution that has reduced strength.
If you use a watering can and do so by hand, then you can also use your hand to flush. In the same way, if you use a watering system that is automated, you fill up the system with flushing solution or pure water rather than use the cocktail of nutrients, which most people normally use.
In the grand scheme of things it is important that the medium is thoroughly drenched. That means you want to double the amount of water used. Be sure, though that the root of the cannabis plants do not stay sitting in water that has settled afterwards.
The Time Frame of Flushing
There are certain times when you should apply this procedure. There are some cannabis cultivators that will use this procedure for their cannabis plants as they show progression through the life cycle. This is one of the most common things done, especially during the phase of vegetative growth when a switch is being made to the blooming stage.
At that time, the nutrient needs of the plant will change. However, you can still use the flushing process to avoid nutrients from building up. It will make the transition smoother.
If you notice your cannabis plants looking abnormally unhealthy and looking as if nutrient lockout is taking place, then you want to flush those cannabis plants.
Signs that the plant is experiencing nutrient lockout occur when the plants have yellow leaves and possibly stunted growth. You can fix this issue by always flushing prior to making changes to the doses of nutrient.
Finally, before you harvest your cannabis crop and prior to applying doses of nutrients, it is best to flush. You can also use bloom boosters to improve your yield. For those growers who use pre-fertilized organic soil for their cannabis plants then it is time to flush before harvesting the crop.
The Last Flush
During the grow cycle, the final flush is also significant. Allow about two weeks prior to harvesting before you flush. Be sure to inspect the flowers so as to decide whether they are ready for harvesting or not. If you exercise the flushing method too soon, you would have cleansed bud stash that is immature or premature.
If you want to wash out all the nutrient salts, it is best to flush with enough water and do so frequently. Make sure you use right pH value in your water because the flushing method will not work if the pH is too low or too high.
