So I have been watching the recent build a soil you tube posts and they really promote pumice and rice hulls over perlite. When making a new batch I will be using that as opposed to perlite and following their ratios (which it seems like I am already very close). My question is for my already existing batches of soil that contain perlite... is there a way to go about ... re amending with pumice and or rice hulls? Or if I want to re approach my recipe do I slowly phase out my old batches and just start a new? Thoughts?
