You'll have to get a safe to get a decent time-lock device.

why on earth would you want one for bud though? I could see, setting a timer on some drying buds so you're not tempted to take them out early, but otherwise, i'd be mega pissed if i put my smoke in a time lock safe and couldn't get it out until hours later. What if I ran out? Shudder...
Primus Reviewed by Primus on . Shocolate Vault for weed? Ok so, So I stumbled across this: Shocolate Vault Jar - Gadget Buzz - Reviews - CNET Asia Basically its a jar that shocks you if you try to open it within the time limit. The problem here is that it doesn't actually Lock, nor does it have a timer beyond 24 hours. I tried finding locks with timers online but there seems to be a gap in this market. Rating: 5
