Great work! Looks like you've really got it dialed in. Those thin LED panels are really cool, very clean look.

I was having trouble with lettuce germination in oasis cubes. The seeds would sprout but most would die before rising up out of the cube. I think they were suffering from damping off because I was keeping the cubes very wet all of the time and oasis holds a lot of water. I since added a small fan to the germination area for more airflow and I let the cubes almost dry out between waterings after the seeds have sprouted. That made a big difference for me.
