A Tasmanian court has heard, an alleged murder victim was growing cannabis and having mood swings, in the lead-up to his death.
Margaret Anne Otto, 46, and Bradley Scott Purkiss, 42, are being jointly tried in Supreme Court after pleading not guilty to killing Otto's husband - tatooist Dwayne "Doc" Davies in May 2017.
The victim's body was discovered wrapped and buried at a Levendale property the following month.
Davies' longtime friend Emma Jackson was cross examined today, saying she helped him set up a shed of hydroponics and that he had offered to sell her half his tattoo business for $35 000.
It's alleged Davies owed Purkiss money for renovating his Risdon Vale home, leading him to become bitter and plan the murder with his wife Otto.
Yesterday, the court heard the victim had previously paid off bikie gangs to allow him to run his tattoo studio.
Meanwhile, the judge has expressed concern over the pace of the trial.
Today's proceedings were delayed by a 40 minute debate over whether a piece of evidence could be shown to the jury.
The case being presided over by Chief Justice Alan Blow, who's recent annual report to the State Government described the backlog of criminal cases in Tasmania has "unacceptable" and "unsustainable".
The trial is already expected to take around 6 weeks.
