I did that earlier today:

[root at box10 bobg]# vgextend fedora_box1000  /dev/sdb4
   Physical volume '/dev/sdb4' is already in volume group 'fedora_box1000'
   Unable to add physical volume '/dev/sdb4' to volume group

[root at box10 bobg]# lvextend -l +100%FREE /dev/fedora_box1000/lv_root 
   Logical volume lv_root not found in volume group fedora_box1000

Not sure what it wants here, it did not accept anything I have tried.

I want to continue using the /home on /dev/sdb. All I want is to include 
all of the remaining space as part of /home. The other home is on 
.dev/sda and is part of an Fedora-19 system. Don't want that. It had 
tried to preserve /home from F-20 beta but I believe I've deleted that, 
don't want it..
