-I open vent 1/4 and don't touch them for 4 days. Then open the vent more and daily take the cover off for a few minutes. After a week I start checking for roots every other day, and if the plugs or peralite dry out I might add more warm water.

When I had my troubles I believe part of the issue was my cloning solution had gone bad. My hydro guy instructed me to keep it in fridge and use only a spoonful at a time. Now I get tiny sized portions from him, they are like $3 each and the size of carmex lip stuff. PERFECT. Sterile and sealed, open the thing. Do two trays, 40-50 clones total, and throw the thing out.
Thank you for the input. I've figured out something that is working for me. I actually started off having too much water in the tray, but more importantly (I think) was spraying the clones with a wilt-stop type product. I also started using a tiny bit of H2O2 and Botanicare's Jump Start in my pre-soak of my rockwool cubes, and started with a lower ph for the pre-soak solution (5.5-5.8). I'm finally getting an acceptable success rate, so much so that now I could use more veg space. A good problem to have I suppose. Thanx again.
