Ok, first things first. You absolutely can NOT do hydro with soil or any "living" medium (in your case peat moss). You should start seeds and cuttings in rockwool or something similar. Put that in the center of the net pot and surround it with hydroton (little clay rocks). This will ensure that you never get your plants to wet or dry, it's almost impossible to fuck something up with that combo. They maintain a great environment for plant growth. You can also get some neoprene disk's (about $5 for 10 or so on amazon) and that will help support the stem while growing, and also keep the light out of your rez.
So, you need to get those girls out of that moss, and into some hydroton (too late for rockwool now I think). Wash the hydroton several times to get the dust and dirt out of all of it. Then you should use some clean water to wash the roots off and completely expose them. Make sure they are completely free of all the dirt. Since your roots are already growing through your net cup, it's gonna be a little more challenging, but not impossible.
Good luck buddy, keep us posted with how it goes.
