Greensand supplement layer (Medium)
right below the high water level when the grow beds flood, I sprinkled about a quart of greensand which is a potassium and iron supplement.

I'm not sure I can really say how it turned out. The system is growing well but then when I added the other three beds I didn't add the layer of greensand but the whole system is doing well. But it might have been doing well without too, who knows.
I use high quality feed and I have dosed a few times with maxicrop and chelated iron since my well water doesn't help on the Iron side of things even with the pH able to drop.

How did this turn out TCLynx? I'm thinking of adding some to my growbed to lessen my dependence on Maxicrop w Iron.
