Aero is a very nice growing method. Nasa grows Aero because it's the best method for growing plants available at the moment for quality, quickness and quantity.
I can't tell the difference between hydro and soil buds, not sure how others can, still trying to figure that out and why organic growers claim better taste because I grow all methods and don't buy it. I was a cigarette smoker for about 7 years and quit a couple years ago, I figured maybe my taste buds weren't right.. Until a lot of friends couldn't tell the difference between the different growing methods either. It's just gotta be grown properly in my opinion. Nutes are nutes. Genetics are genetics. Hydro is the best for quickness and cleanliness in the grow room and is actually healthier than organic soil grown plants because of refinement of the bad stuff out of the fertilizer. Organics can't refine anything and can contain selenium, fluoride, radioactive stuff like radium ect. Not as clean as it sounds but I still like supersoil. Hydro is just easier and cheaper.
