Hello halfway,
I saw the video, it looks like it's like a nice simple setup, and should work great. You don't even need to light proof them because of the color and thickness of the plastic from what you said. Looks like you will have a nice supply of lots of good lettuce. I think I may have asked you this before but don't remember. You mentioned using silica stone for a growing medium, and that it's porous. Where do you get it? Is it pH stable? Is it easily available and less expensive than traditional grow rocks?
