I think some with trained taste buds can notice diff grower growing same cut easily.But a well grown indoor bud without carbon overload in my room might get some sort of neg critic but not from being indoors or hydro nor using salts. JK

I pulled a plant out of the ground about 4 years ago and stuck it in a used cooler/hydro-bucket. New roots started shooting out while the old ones were sloughing off. I have finished some really good weed, dozens not hundreds of plants with 5 gal buckets and an air stone. I have seen a lot of things above that would definitely have turned me away were they true. I don't have a ppm meter. I do have a ph meter. Hydro is easy dirt is hard.
