Ive never grown hydro... but from my knowledge and and information ive gathered... Its self preferance really. I mean I do think there is some advantages in hydro...like... NO OVER WATERING... I dont really completely know the concept of hydro.... but I cant imagine you could possibly overwater a plant if its roots are submerged in water.But then comes the complexity of it.. so not just some noob grower could grow hydro and have outstanding results.
This is all just MY OPINION... Ill wait to see what the pros have to say.
