There are certain compounds of nutrients that you do not want in your final product. By flushing your plant with plain water before harvest, it will force it to use up these unwanted compounds which will result in a cleaner product.

Plant Flush will stop any further intake of nutrients through the roots and will cause the plant to only use the nutrients stored within the plant.

This will greatly reduce the amount of time you need to flush your plants in order to achieve a cleaner end product!

Ask a Question
  • Re flushing: I'm half way through week 8 of your program and want to know when to start flushing. Am I starting late or should I start after I finish up week 8?

    Hi Rick,

    It depends on your medium, how long your grow is, and if your plants feel ready to be harvested.

    Generally you want to flush towards the end of your grow when you're close to harvest. Some people suggest to start flushing two weeks before the end of your flowering stage but it varies with each grow. Also make sure that when you do flush, to flush with straight water the last 3-5 days before harvest.

    Here's a link to an article about flushing to help you out:

    It sounds like you're at the end of your flowering stage so you may be starting a bit late, but that's okay because you also don't want to start too early. Simply start flushing if you feel your buds are ready, and good luck with your grow!

    Have a great day!

  • When using with soil, do you dilute this or use it straight?

    Dilute 1 mL per 2 litres of water.

  • My plants are in 8 to 9 week flower cycle what week do you suggest I start my flesh in thank you

    We recommend using Plant Flush in the last 2 weeks before harvest.

  • How much do you use?

    For use as a system cleaner:

    Use undiluted WITHOUT PLANTS in the system.

    To treat over fertilization:

    Dilute 5 ml per 1 litre of water. Run through system for 36 hours then empty reservoir.

    For use as a pre-harvest cleanser:

    Dilute 5ml per 1 litre of water. Run through system for 3-5 days.

  • Does it remove the vitamin B flavour as well?

    Hello, thanks for the question.
    The Plant Flush product will stop the roots from absorbing anymore nutrients, 
    this then forces the plant to use up all of the remaining nutrients in its system.
    It would be beneficial to do a feeding of Plant flush followed by 1-2 weeks of flushing just pH'd water.

    Best regards
    Happy Growing

  • Does plant flush work in soil?
