Well, sometimes you have to admit failure. I shelved the wheel, the soft micro greens I want to grow do not like the rotation much. So I went and bought the IKEA VÄXER system.
I didn't bought the light they sell though. I used their light fixture and just glued some blue and red leds under it. Much cheaper.
The plants moved over to the new system an are much happier now. The first harvest was quite tasty.
