Youtube user Guy Brown inspired us to make seedling cups using toilet paper. We decided to go this route because we have a tray for rock wool or coco plugs and this allows us to make our own plugs relatively easily and cheaply.
We tailored the tool above for our specific tray but for those interested it’s a 5″ length of 1″ SCH40 PVC and a 10″ length of a 5/8″ round dowel from HD.
Some adjustments we made to the process in the video:
- Three sheets instead of just two
- After one wrap around the PVC, spritz the folded paper strip lightly with water to help get the paper to flatten out and bond to itself
- Spritz bottom of cup before tamping it down
