look to see how tightly its trimmed up and the coloration shouold not be just green. good weed comes in many different colors, potency of the smell is a key to figuring out quality, look for white buds, lots of crystals, and at least 3 colors such as white, orange and purple. or yellow red and white with a bit of green. AND MAKE SURE ITS NOT BRICK.. if you find seeds, or its real leafy and plain dont get it your wastin your money on it. find a heddi connection
