Well it ha been 2 weeks sense posting the last pictures. The lettuce has been growing quite fast, so I thought I would post an update at the 2 week mark from the last pics. You'll notice the roots look brown. I don't know exactly why that is for sure. The
nutrient temp hovers around the low 60's, pH is kept close to 6.0 and I am sure the
nutrients are fine. I believe it is because the bubbles from the air stones are inadequate, so the roots are actually drowning/suffocating. Even so they seem to be growing quite well, so I haven't been worried about it. I see a salad in my future.
I covered them with the shade cloth to keep them out of the direct sunlight. It's not hot (upper 70's low 80's) but they seem to do better in partial shade, rather than direct sunlight. You might notice the front plants seem to be smaller, your right. One of them has always been that way, the other my mom keeps picking leaves off of for her salads. I'm not actually sure where she gets all of them from, she plucks them when I'm not looking. She is getting to be worse than the rabbits. In fact not 15 minutes after these pictures were taken, I caught her walking in the house with 3 more leaves in her hand. I don't really mind, but it confuses me in how they are growing when she does that without me knowing.
