One last question before I start, I've been reading some glogs. When germinating seeds they need no light til they hook right? I see some put lights on right away and others don't . If I choose not to use lights .. once they hook they need to go under lights right? , but then does the dome come off? I'm not sure if I should germinate them in one tray then move em into a empty tray once they hook since I'm using plugs ( this presents some space problems ) or if once I see some hooks pull the dome and put the whole tray under the light? What do you guts suggest?
