One-piece cloning pod. Print, remove supports, gather sponges to add to the rectangular cut-outs at each end add peat moss and cloning gel and you're ready to go.


Skin (remove outer layer of plant stem) and slap this on there (filled with peat moss and cloning gel) and watch the roots grow. Then snip just below the pod, remove plastic pod and replant. You have a genetically identical clone of the original. But still, where did the lighter fluid come from?
