In this video, I'm going to show you how to make a mini Kratky system for growing lettuce. I logged the entire progress which took about 5 weeks. Depending on which variety of lettuce you're growing, it may take more or less time. Below is the nutrient mix I used in this video.

I got the seeds from Jim Conner. He grew the same lettuce recently and it was much more massive. Please see link to his video below.
