Hone's motive for the robbery was to obtain cash to buy more synthetic cannabis, the court heard.
Lawyer Craig Tuck described Hone's offending as "unsophisticated" and said the attempted robbery had been committed by a "desperate young man".
Mr Tuck said Hone had participated in a "very powerful" restorative justice meeting with the victim and had shown genuine remorse and apologised for his actions.
He urged Judge Christopher Harding to grant Hone leave to apply for home detention if his sentence came within range.
But Judge Harding said even with discounts for early guilty pleas, his age and expressions of remorse, the end sentence would be well outside home detention range.
Hone was ordered to pay $50 reparation upon his release from prison.
