Since nobody is answering here, I'll just throw in what I've heard about
some south FL commercial growers. Many do spray monthly to ward off
problems. Not sure if they vary the product.

Hey, before I even read any replies, I'll ask a related question that I
keep wondering about but always forget to ask:
I get tired of my semi-hydro pots turning green then nearly black on the
inside surface. In fact, other plants in normal, but clear plastic, pots
turn green to some degree too. Can a physan solution either clear this up
or at least prevent it?
I've been half tempted to fill up the pot with a bleach solution then see
if I can flush it out in time to not kill the roots. Trouble is, I don't
have a plant in semi-hydro that I am willing to kill.
