The present invention provides a system for transporting plant clones that have developed root systems outside solid cultivating media. The transporting system comprises stem collars that hold plant clones. The stem collars are made of biodegradable materials so that plant clones can be transplanted to the field with the collars. The plant clone transporting system also comprises a collar tray to hold stem collars and a portable tank to hold water or solid media that holds water, such as rockwool and perlite, to provide favorable conditions to the root systems of the plant clones, so they can survive a long transportation.
