I don't understand why people here think their grow will be better if they make things more complex. Chances are you're just going to screw it up. Fine, whatever, have it your way. But you're going to spend years on these boards, never getting quite right. Besides, the only issue I was addressing is fertilizer. That's it, nothing more. I know about light and air and water and drainage, etc. To confuse what I write shows that you folks need to lay off the weed. Have a nice life, everyone, and good luck too as you're going to need it.
