Its been 3 days, should i leave it for another 4 days (i.e. 7 days) or will it be fine to pop now? Temperature in the shed has been a constant 8 degrees Celsius at the moment.

If you can get a heat lamp and get it up to warm to the touch that should be enough to get it cured enough. (it will continue over time anyway) If you tap it with a screw driver blade and it sounds hard like steel your good. If it sounds like cheese or wax your not there. When its cold I increase the amount of hardener which helps. ( note : only for polyester NOT epoxy) Hope this helps. Fred
