I'm in Ocean Forest on week 11 of a Blue Dream photo grow. I need to flush some of the salt build up from the soil and picked up a bottle of FloraKleen since I was out of my typical Sledgehammer flush. I've had lots of folks suggest FloraKleen so I am giving it a try. FloraKleen says to mix the proper dosage into water and then water until I start getting runoff. That's all it says but how does a small amount of runoff clear salt buildup???? What is the best way to use FloraKleen in your opinions?
