How long to let concrete cure in sono tubes?
 

Using sono tubes for piers on deck build. What's appropriate time to wait after filling tubes before can begin setting posts, beams and framing? Really need start next day. Would fast setting Quikrete be best?

Time is not a big factor since the construction loads are really minimal and a fresh Sontube is many times stronger than a wood post. Just make sure your embedded plates are there and go to it in a day or two. The concrete will cure faster than you can build enough to put loads on it.
