This video demonstrates how to grow watercress from seed by a suspended pot, non-circulating hydroponic method (commonly referred to as the Kratky Hydroponic Method).

    Dr Bernie Kratky, thank you so much for this video. It worked exactly the way you teach it.
    We used to pic watercress in the county when kids, now I can grow it nearly year round and invite friends with it.
    Wish you the best

    I gave the method a go using rockwool and placed each net pot in a mason jar. So far the root development has been poor after 4 weeks and leaves development has been slow. The watercress seems to develop a fair bit of roots at the stems. Does that mean I should top up the solution so the net pot is once again submerged?

    Watercress create roots spontaneously from its stem if they are too much together. Any humidity and they start to grow.

    I saw your method on MHPgardener's channel and that got me started in hydroponics and making videos on YouTube. Thanks so much!

    Thanks Berny. I talked to you many years ago about gardening here in Hawaii. Only recently did I get interested in growing watercress and the hydroponic method. Those roots on the lower stems, can they be succesfully replanted? Or do they suffer the same fate of more disease and insects as allowing the cut rootball to regrow?

    Thanks for the awesome video. It got me interested in growing watercress myself. Wondering what is the growing medium used in the video? I would like to be able to seed directly in the net pot without having to transplant them after. Is that just perlite you are using or a mixture?

    How many galons for 4 onces of nutrients?

    Remember, never juice and drink watercress straight and undiluted. It is so nutritious that it can cause irritation to the mouth, throat, and or stomach .

    I thought you demonstrated on another video that a floating model worked better?

    just discovered your work. very interesting . Q: can Hydroculture clay balls be used instead of Peat+Perlite soil media? ( i experimented gnat, water insect by using Peat moos media)

    Is it possible that the little roots along the stem allow the plant to grow out like a ground covering plant?
