Basically, I don't have a good understanding of what hydroponics is so here's my questions -What is hydroponics? -How expensive is it to grow hydroponically? -How many ounces would an average plant have when fully grown hydroponically and how long does it take to grow completely? -Is any special soil or grow product needed? So please someone who has a vast knowledge of what hydro is introduce me, and explain step by step what I buy to do this and how I grow the plants different than normal...because If I'm gonna grow I wanna grow big plants not 2-3 oz.
