No plastic , I have mine in the cloner insert , it is round black coller . All the roots below the coller are not restricted. I am waiting to see if the additional a bubbles help . Currently it is producing problem ten fold the amount of buddles then it was. It really does look like a jacuzzi .

Thanks
