Greetings, I am new to hydroponics and I am setting up a deep culture system... I live in a small town with no decent suppliers near by... before you ask yes I know about the internet...The Medina is available locally and the nutrient is the last thing I need... I am heard that people have used Medina Shasta grow as nutrient... has anyone had any luck with this? If so what concentration did you use? If the Shasta gro is not acceptable what do you recommend for someone getting started that does not know much about nutrient?
