There are so many other reasons for this to happen that it is probably a
mistake to assume that cold substrate is the cause. I am particularly
unimpressed by the evidence of the Glosso and "baby tears" (Hemianthus
maybe?) disitegrating.  Both of these plants are rampant growers under just
the right conditions, and can be the dickens to keep growing if there is
something not to their liking. OTOH...

Both of these are easy to do, inexpensive, can't hurt, and might help.  I
still think there are probably other factors involved in your lack of success.
