As far as watering big pots correctly goes...
I've really been combining bottom watering thru the saucer, then finishing with normal top watering of container. I think this is one of the better ways to ensure that the entire mass of soil gets thoroughly watered. The key is to go slow and steady through the entire watering process. Or one could invest in blumats.

Gfcollective, As far as mulching indoor containers goes, maybe it isn't for everybody but it makes lots of sense if you think about it. I also have not been following member curso's journals, but I think what we are doing is a little more than adding canna leaves to used soil and recycling it. Simply put, we are just trying to replicate what happens in nature, but indoors in containers. I don't think the soil microbes have any idea that they are indoors, in a container. The concept of creating and nurturing a SFW driven growing system indoors is fascinating to some, like me, and the results are amazing.
Edit:
In the future I'd like to grow indoors in one large bed, using blumats to water. Container size is one of the limiting factors for yield, I think all agree with that??..or maybe not, idk. Anyway, massive containers with a system to keep them ideally moist all the time sounds like the ticket, easy and effective.

SG,
I think mold is scary, although I have seen fuzzy mold in cooking soil bins, my mulch is never moldy. If part of it was moldy I'd probably toss that into the trash, if only to make me feel better about it. I don't see any mold on your mulch in above pic though, so I'm confused. Maybe it was on another pic on previous page. The mulch in picture above looks good. The point really is just to put SOMETHING on the top of your soil to protect it.
Edit edit edit, lol:
Here's a quick video a gentleman named Jeremy made, of the life under the barley mulch.
Not for the faint of heart.
