I'd normally say leave for 5 to 7 days but if he's such a good striker it maybe worth trying again tonight .
Just has to be WARM . I have a hairdryer in the snake room. As long as he shows interest or tongue flicks then offer warm , especially if he's in his hide .
Just keep warming and offering till successful .
If there is not even a tongue flick then best leave it for a while . Remember low lighting .
I've even used a torch in the past but don't shine it near the snake of course
