Hydroponic Zinnia Flowers

Zinnia flowers were grown with a hydroponic method that doesn’t require electricity or mechanical aeration similar to a method for growing hydroponic lettuce.
One of the highlights of this video is the viewing of the massive root system which developed in the moist air space between the nutrient solution level and the cover of the growing container.

    Have you tried trimming off the air roots to see if they do anything? I think they just subsist in the humid zone doing nothing. I was too lazy to test it this summer though.

    I like the shirt! The Zinnia’s are beautiful. I’ve grown marigolds, they weren’t quite as nice. Thank you for the poem, I didn’t know you were a poet. Big thumbs up, good to see you.

    I love Dr.Kratky! Most underrated channel on youtube. Are you taking grad students? probably not, if you are emeritus 🙁 Please make more videos, the world is going to need all of your unpublished knowledge in addition to all of your published knowledge. Really the videos are more accessible to the non-college educated anyway. New idea: can you make videos on the topics of all the papers you have published, papers you never got around to publishing and seminar/conference presentations? Can we get a nobel prize for the father of resource efficient, universally accessible, non-electrical, unpatented almost free hydroponic gardening? I know i’m asking a lot from a retired professor who still keeps active professionally but a successful YouTube channel could fund a small team of grad students to make the videos for you 🙂 I’m so inspired, everyone is getting a kratky inspired, reused plastic, home-made grow system for their birthday this year!!!!!

    Is there a place in Hilo to get Masterblend? Or do you order online?

    Fabulous I’ve got some violet impatiens grown this way too they are doing well even with very strong winds. Question any other flower ideas?

    How much extra water + nutrients did you end up adding?

    Thank you dr very very much.

    Very colorful and nice display of zinnia flowers, I was happy to see you making more videos. This year I was able to hide a container in the landscape plantings, in which I grew flowers using non-circulating hydroponics. It was a perfect way to get out of watering chores that is common with typical potted plants. Maybe you can supplement your greenhouse vegetables with containers of flowers? It would be a colorful greenhouse!

    If you go to the Happy Leaf LED website, you can find a lot of videos on how to grow a variety of plants using the Kratky method all year long.

    The weeds were actually pretty. And they really did look good with the zinnias. They were probably taking up too much water though huh?
    Also your weeds kind of look like cosmos. Which is a flower..

    How about growing beneficial insects to eat aphids and such.

  21. Truthbetold on April 16, 2021 at 12:26 am

    Dr Kratky, you’re a Godsend : )

  22. NupeAtl on April 16, 2021 at 12:29 am

    Who’s the originator of this method? I thought it was Hideo Imai from the 80s.
