Great set up man. You may just want to get some reflectivity going on in there though. Think of all of the light rays (lumens)that are being wasted on the closet walls and floor. You got a really good light set up there and should be looking to maximize getting it directly to the plants. I would recommend mylar paper as I've had really good experiences with it. Did the plant in the last pic sprout up while in the dwc or did you put it in a humidity dome first? I'm getting stuck on that particular stage in one of my current grows and nothing is sprouting in dwc or in a humidity dome and was curious how you've been getting yours to sprout (I assume you germ through p-towel method or somethin similar).
