Neil Kengni scored his first goal for Forest Green and Gabe Kircough added a second as the hosts secured a 2-0 victory over Wealdstone at the New Lawn.
Wealdstone goalkeeper Dante Baptiste saved attempts from Laurent Mendy and Kircough before Jayden Clarke sent a huge chance just wide.
The hosts finally broke through in the 41st minute when Kyle McAllister flicked the ball on to Kengni, who applied the finish to open his Rovers account.
Kircough would not be denied a second time, adding a cushion three minutes after the hour.
