I have the same exact light on my clones. I took out the 2 outside bulbs and posted a thread about the light level and all the feed back was that it was just fine. You need to take the plastic off your rockwool and mist 2-3 times a day, do not soak them. Do not give them any nutes til you see roots coming out of the cube (10-15 days). I take the lid off mine to let the oxygen out and blow through the plants a few times before I put the dome back on. Mine are 6 days old and doing great. I accidentially pulled one up a little so I pulled it out and there are roots starting to form already..... good luck...
