Germinate Bruce Banner

Ok folks I’ve had two seasons of successful outdoor grow and one indoor grow in an Octopot.
Now I’ve got a high tech hydroponic system with excellent lighting. My question is, once my seeds show a taproot and put in them in my wet rock wool cubes what is my next step. Should I put the blocks in a plastic clear top container container or directly into water reservoir under my lights.!My 1st hydroponic grow.
