From the --help output (and wiki and forum and ...) you can easily see that the options you are looking for are:
This is the case for oclHashcat and also cpu hashcat (since more than 1/2 a year, see https://hashcat.net/trac/ticket/572 ).
increment mode works the same way for cpu hashcat and oclHashcat, i.e. no increment by default, but if you specify --increment (ocl)hashcat starts to increment from length 1, unless you did specify the --increment-min option.
Code:
--increment Enable increment mode
--increment-min=NUM Start incrementing at NUM
--increment-max=NUM Stop incrementing at NUMThis is the case for oclHashcat and also cpu hashcat (since more than 1/2 a year, see https://hashcat.net/trac/ticket/572 ).
