Thank you. I use a mix of BLUE/RED and WHITE (daylight) LED bars for lighting as that gives the best spectrum (leaning towards blue) for what I need and uses much less electricity. The plants are started in rockwool and moved to the netcups with some clay pebbles on top to help control evaporation.

I have a full post on how I built it here:
