How long do I have to put my clones in soil?????

My clones have rooted in the peat pucks and look pretty nice. How long can they sit out before the exposed roots start rotting. Also I noticed some of them looked kind of fuzzy. Is that normal or is that the because they've been soaking for too long? If I added a few drop of peroxide would that help?

It is time to transplant now. Transplant plugs when the roots are coming out of the sides and bottom of the plugs. The fuzzy hairs are micro roots branching off the main roots. If you see these on the outside of the cube it is time. These small roots will dry up easily on the outside of the plug. Dont use the peroxide at this time.
