How To Build An External Pump Cloning Machine

In this video I explains and shows you how to build an internal pump cloning machine.
Hopefully this at least sparks some ideas for your own creation.
Running the pump internally helps keep the water much cooler in a clone machine and avoids problems like roots getting into the pump.
This is a lot of drilling so please be safe while drilling and take your time. Thanks for watching!
