The Kratky Method was first published in a paper in 2009 by B.A. Kratky, and describes a beautiful method of growing plants in a non-circulating hydroponic system. It’s a very simple, yet effective, way to grow plants hydroponically. Great for leafy greens like lettuce, kale, spinach, and a variety of herbs.
I’ve even seen people do Kratky tomatoes or Kratky cucumbers, though I haven’t grown them myself (yet)!

can you grow other food other than lettuce with this system ?
How does the Rockwell work from seedling? I don't understand if I have to keep the tank full to keep the rockwell wet or if it will obsorb the water?
What are the nutrients you keep talking about?
What specs of LED lights do I need to grow indoors?
The Amazon link on your website no longer works for the nutrients.
My kratky jars are not as successful as growing in the IDOO system. The only difference is the light. I don’t have a suitable window, so I bought a blue/red light. Can you recommend a better light for a small setup. Is it better to use a white light along with the red and blue? I am in Australia. Thanks.
Can you root tree cuttings like this?
Hi EG! I'm just getting into hydroponics and it's little late in the year for chicago. I see lettuce and kale can grow in cooler temperatures when in soil. Do you think I would be able to start kale and lettuce now if Chicago gets to 44 degrees to 56 degrees fahrenheit in november? I was assuming that it should be enough time for the vegetable plants to harden before weather begins to drop some more. I've also read that plants grow faster with hydro. Let me know if you think I can get a good crop for a hydro newbie or if my plants will be dead by the time November comes!
Kevin, Thanks this is exciting for me Than k you fort all the valuable info.
How do you find out what a plant needs (& their amounts) over 30 days ?
I have read some where that EC & pH has to be monitored periodically. How could we say it practically hands free!??
finally someone who actually explains the idea!
Pretty cool, but how about natural (homemade) nutrients? do exist?
B.A. Kratky is alive and well. He makes videos and tells everything he knows. dakineapproaches is his youtube
Very informative step 1!! I'm on it
How does this keep stagnation and bacteria from forming though?
I have had such great results using the Kratky method…Great Video!!!!!!
interesting where I find the video x the nutrients? thanks
We can modify the self-watering soda bottle planter in using the Kratky method.
Just put lots of holes in the planter / pot; and no soil and no wick

Lettuce does flower
Thanks I am trying it
I do this method but with airstones as well and the nutrient solution 4"-6" below the net pot, its essentially and RKWC system lol
How do I figure out how much nutrient and how much water I need for a given plant?
Ag, hierdie video het my laat glimlag, dankie! 😀
Are net pots really necessary? Can we just use glass bottle with thin neck and either let plant hang or fix it in place?
Germinated some popcorn seeds in a medicine bottle and have no soil.
So time for hydroponics lol
I've been studying aquaponics and discovered a great website at Keiths Ponics Site (check it out on google)

Question, can you refill the tank if your plant is like tomato or eggplant?
I do some classes for school kids and Boys and Girls Club – I would like to snip a couple of photos and graphics for use in these classes. Do I have permission?
