Use or lose perlite screenings
I've just rooted a bunch of jade cuttings in perlite that was screened through 1/8" mesh. Sadly, an awful lot of my "coarse-grained" perlite slid right through that mesh.
I've seen some people talking about using perlite that didn't fall through insect screen for the 5-1-1 mix. But can i use all perlite that fell between the 1/16-1/8 range for my 5-1-1, or do I need to mix it back in with bigger chunks of perlite as well?
And then for the dust that passes through the insect screen...is that total garbage? Usable to make hypertufa? Good for starting seeds?
