I'm in the process of making my muk. I was wondering how deep would you have the perlite go? The container is about 12 inches deep. So I don't think I need to have perlite all the way to the bottom. I was thinking maybe having the bottom couple inches, maybe 6or so just peat and up top where the plants are using the perlite with a top layer of just peat so the perlite does not come up to the top and look ugly. Also around the base of each plant have some LFS too. What you guys think?
