Has anyone used PBH (parboiled rice hulls) as a substitute for perlite in their growing media? If so what are your thoughts on it. We use a lot of soilless mix on the farm and the price sure is good.
Bloody nurseries and the like look at me as if I have seven heads and three dicks sprouting from my neck whenever I ask around about rice hulls. Do they float at all like perlite?
