A cardinal lambda is called omega-inaccessible if for all mu < lambda we have mu^omega < lambda . We show that for every omega-inaccessible cardinal lambda there is a CCC (hence cardinality and cofinality preserving) forcing that adds a hereditarily Lindel'' of regular space of density lambda . This extends an analogous earlier result of ours that only worked for regular lambda .
