i just sifted my first two bags of turface mvp thru 1/8th hardware cloth.i did not get enough to fill 4 3.5 gal rubbermaid bins half way.it was about 30% after sifting.i will get more later this week.
hey, i tried the 1/8" screen for a couple of plants and found it to be a little too loose.
i'm using the regular aluminum window screen from lowes.
after sieving with this you should get about 15 gals of usable material from 2 bags.
