Erin Patterson spends most of her day alone in her cell and can only speak to one other inmate through a mesh fence.
Patterson, 50, was found guilty of murdering three of her in-laws - and attempting to kill another - with a lunch laced with death cap mushrooms in July 2023.
She will be sentenced on September 8 following a pre-sentence hearing on Monday in which relatives of the victims shared emotional statements at the Supreme Court of Victoria.
The triple murderer is behind bars at Melbourne's only all-female maximum security prison - the Dame Phyllis Frost Centre - at Ravenhall, 20km west of the city.
Patterson's life inside the jail since her arrest in November 2023 was revealed in court as her lawyers fought for her to be handed a non-parole period.
