Thanks Opie. That's a start. As I've never had any problems doing as I stated, and plan to continue, All I am curious about is technique.

When I cut or break-off a leaf, what's left on plant 'bleeds'. Does not 'bleed' when peeled. I'm guessing there's a cambric-type layer (or some sort of layer) that allows plant to lose a leaf without leaking it's sap, or opening an accesss point for bacteria.
Most definatelly a guess, tho.

The issue isn't really important, I'm sure...I'm just a med grower that's a bit curious.
