Regarding Clones for the medical market...

First and foremost is Rockwool the preferred medium with which to use for Clones for sale to patients? I know many use the aeroponic EZ-cloner type set ups... and Im a little stumped on how you would be able to root clones n an EZ-cloner if theres not some kind of rockwool etc type plug? Do the clone vendors in med states simply root in plugs period?

I would say a lot of vendors do root in inert cubes of rockwool or coco. Then again I'm not a vendor and maybe someone will have better insight on this.

The ez cloner concept is ideal when you're going directly into a substrate like soil, promix or coco.
