VIDEO: Hydroponic Lettuce with Different Environmental Growing Conditions: Nature vs. Nurture


In this video I follow the development of 12 hydroponic baby lettuce seedlings to see how they grew and ultimately matured in varying lighting conditions. The seedlings all started out the same way, planted in rockwool. Then some of them got thinned out and moved onto clay pebbles, and some others got rehomed into hydroponic Kratky systems. This is a classic nature vs nurture story. All the seedlings started out the same, but over time were subjected to different environments as you will see.

  1. i like the idea of just growing the lettuce on the clay pebbles. there's always something new to experiment with. good job. i'm in the process of setting up a kratky tote to grow a small tomato and just watched your video about you setting up your first in a tote. how did that turn out? did it grow normally and fruit for you?? thanks. keep those videos coming 🙂

  2. I'm trying to grow some lettuce using the Kratky Method, but I'm using 5000K LED lights. They are not growing as quickly as yours. One variety bolted. I'm wondering if I need to get grow lights instead. ???

  3. Is there any way you can monitor the temperature of the hydroponic solution
    in these experiments?….apparently the temperature of the solution
    has an effect on the plants ability to absorb the nutrients…
    Thanks for sharing……

  4. Thanks for another interesting video. It looks like you have good luck with Black Seeded Simpson lettuce. Are there any other varieties that do well for you?

  5. Thanks for all your great videos! I'm trying hydroponics for the first time and my lettuce looks great, but it tastes terrible. It is too bitter to eat. Do you have any suggestions.

  6. Definitely interested in seeing the lettuce on clay pebbles– I used the method in your previous video to get summer savory to sprout in a Kratky setup in hydroton without rockwool. I ended up having to adjust my water levels though: my "basket" unraveled and one of the seedlings germinated much higher than expected.

    Happy growing!

  7. Did the lettuce planted in just the rock wool taste any different?? It is much greener. I'm wondering if that means it absorbed more of the nutrients and is therefore healthier?

  8. Was there a taste difference between the darker green ones in the rockwell cubes and original cookie container and the nice ones in the coffee containers with the LED light?
