Splashing it with water you also jsut splashed it with various heavy metals, not very good dude not good at all you can now enjoy smoking metal once it dries b ut hey itll be so little who cares right.
As for what degrades thc , Light and Heat.
If you need to moisten some bud because its too dry (which is ridiculous bud cant be too dry, if it is the dmg has already been done (likely heat light exposure) then get leaves from a tree of sorts that smell nice n dont have bugs or mould on em or nething just like a tomato plant, chuck em in the baggie overnite with your bud not in contact but near and the bud will absorb the moisture from them, thats the natural way of doing it other way would be to put a slightly damn cotton wool ball in the baggie (not in contact) with it,,
