there really is no specific difference. Usually, and I say usually, because there are exceptions, indoor is usually more potent than outdoor. Only because you can totally control all of the aspects of your grow. Outdoor grown typically tastes and burns better than indoor b/c it is usually all organically grown in soil with natural ferts, whereas and indoor hydro setup normally uses chemical ferts and if they arent flushed completely before harvest than they can taste and smell off. Sometimes they even spark b/c of too much nitrogen still in the bud.
gs8778 Reviewed by gs8778 on . what's the diff? besides color, what is the difference between indoor grown and outdoor grown weed? (besides the obvious, i'm talking QUALITY here). Sometimes i get the feeling that outdoor bud has a piney smell to it while indoor bud often smells a little bit like vinegar. it may just be the type of bud, but is the only difference i can make.
