Lighter Gritty Mix questions?
Love using gritty mix but need to work with lighter ingredients these days. I remember Josh (greenman) was using pumice, perlite and bark, mentioned quartz but not sure if that was always in the mix? Was that in equal amounts? I've also read Al (tapla) suggesting some could try 3 parts bark, 4 parts perlite, and 2 parts turface. Mike (meyermike) at one point spoke about trying 1 part fir bark, 1 part perlite, 1 part turface. Can anyone share their experiences with any of these mixes, or others, before I dive in? Should I still add gypsum at 1TBSP per gallon if I'm already using Foliage Pro?
