oops, messed up my first response, here it is again..
How can you tell if a plant was grown indoors or outdoors?
imo, it's kind of hard to tell if a plant was grown indoors or out..
With soil or hydroponically?
my one friend says she can always taste bud that was grown in hydro vs soil.. me, i'm not that good i guess..
How big the plant was?
the bigger the plant, the bigger the yield usually, all other things being equal..
What can we learn from knowing a strains parents?
knowing a strains parents will let the grower now what it's offspring will be like to an extent.
What do some of the popular terms like OG mean?
like rm3 said, some people say og stands for ocean grown, others say it's original, or original gangster if you will.. no one really knows the truth..
What type of main smells do buds give off (fruity, piney, spicy)?
buds can give off a ton of variety on terms of smell.. popular are piney, say an og kush, to fruit smells like banana, pineapple, so on and so on, to hashy..
How moist/dry should the bud be?
about 60% or so is a good starting point.
