  I’m shocked! I thought the kratky wouldn’t grow nearly as fast as the one with the air circulation water system. Thank you for stopping me from wasting time and money on pumps and electricity

  Your channel is really really useful and so well done. No nonsense- you just get to the point and your experiments are really thorough. I'm trying hydro for the first time ever, after decades of soil growing. I'm not getting around so well after cancer surgery and this seems like a great gardening option for folks with limited mobility, like seniors. Thanks for the inspiration!

  The top roots are called air roots. Too much bubbles can cause the water roots to slow but in longer grow time plants dwc will catch up and surpass. Lettuce grows in short spans especially indoor and hydroponically so they do well in kratky, low maintenance setups. I run my pumps at the same time as my lights and my 5 gallon bucket dwc is growing basil, tomato and watermelon 2-5 times faster than my soil comparisons.

  Your test produced some interesting results. Its amazing how the roots adapt to the different environments. The results of this test give us a better understanding of the plants oxygen needs and how it develops to achieve survival. I very much appreciated this comparative test on video.

  Thank you for showing us this comparison. I'm starting out with Kratky and am happy to know it works as well, if not better than, DWC. I'd love to see a comparison on fruiting vegetables as well!

  Kratky, what an amazing method!

  Great experiment, since root size with Kratky can depend on container size and the amount of nutrient drop, using 5 plants in a 5-gallon bucket might create competitive growth and nutrient use that would make bigger lettuce heads.

  That's interesting. Every other DWC vs. Kratky had the DWC growing faster and the root systems always much denser.

  Thank you so much! Saved me from the extra time and electiricty of setting up bubblers!
