Wow! That's a really good idea. In addition to getting them planted with minimal root damage, it would spread the roots through they hydrotron, which would stabilize the plant better.

I used an aero-cloner for mine. Left them in there way too long so they had really long roots. Getting them out of the cloner was a bit of a pain because they were all tangled up with each other. But I just coiled the roots up in the bottom of the net pot and then carefully added they hydrotron around the plant stem. It worked....the roots have grown down into the DWC res and the plants are growing nicely. But they don't seem to be anchored in there very well.

Ah well....maybe next time lol.
