sorry I didn't elaborate, but what I've read is that the current created by
the substrate heaters in concurrance with turbulence created by HOT filters
negate any postive affect a SH can offer...

is that better? I dont' have any reference for this, just what I've read
over the last 2.5 years or so....

Can using substrate heating eliminate Anaerobic activity in a
compacted
substrate, through means of convection?
