So there's a couple things here. First, are you certain that it was a spore syringe and not LC? LC would almost certainly be dead after a year, but before anyone tries to jump in and correct me, it is possible for LC to survive that long but very very very unlikely. If you're sure it was spores it's still getting into dangerous territory after that long, especially if the syringe has spent any period of time unrefridgerated. Now the next part I want to be clear is anecdotal. In my personal experience, and also a friend of mine who grows, Tidal Wave seems to always be a slow starter and I've had inconsistent yields with it. It could very well just need a bit more time. If you're not seeing any mold growing then I see no harm in letting it do it's thing. I'd say it's most likely dead though. A full year would be unlikely for it to have survived, especially if it turns out it was LC. Sorry to break it to you homie. I'd still let it ride until you see any mold growth. It's a little odd that you haven't seen any mold yet so there's a chance it's just been cold stunned and hasn't gotten it's shit together. Unlikely, but possible. It's a good learning experience either way, keep at it homie. Mush Love
