The racking cane in the receiving carboy is to minimize splashing? I thought I read somewhere else that splashing might help with degassing? Your choice, a short cane will splash and a long cane does not splash.
The outgoing carboy is NOT sealed? If using the orange caps, one hole is left open? There is no cap on my supply carboy, Wade uses a cap with one hole open. Again, your choice.
The receiving carboy must be GLASS? The outgoing one can be PLASTIC? All of the vacuum is in the receiving carboy which should be glass, the supply carboy has no vacuum, therefore, no pressure and can be plastic.
