My laterite substrate is over 8 years OLD!  In the two weeks my tank has
been set up over a 3 year dormant period, my Glosso is spreading like a
carpet and the other plants are doing EXTREMELY well. The only thing I had
working was the substrate heating cables in the dormant period, so the
convection flow was still flowing through the laterite.  Maybe this is why
no hard spots to note as some industry experts have maintained that would
happen to laterite over time??  I have not seen this and when I was doing my
initial two week vacuum cleaning after a LONG period of time, if I went down
too deep, the Laterite clouded up in all spots I attempted to vacuum.

Nice posting Tom on some issues with aged substrates.  I've been VERY
interested on this. I know my methodology is not very high tech, it's only
looking at the physical aspect of the Laterite, but so far my plants are
taking off after the initial laterite placement, 8 years ago!
