also, something to keep in mind.. since your plant got water (from the rain the night before)... the buds will more than likely take a bit longer to dry.
this is why I generally like to harvest once the soil is dried up..
either way though, you'll be alright and so will your product. But again, just be more patient because it WILL take a little longer than normal for the buds to dry.. because the plant got watered the night before you harvested.
good luck
peace.
