Al's mixes: I need a quick course in screening!
Just back from the hardware store where they sell hardware cloth in 1/2" and 1/4" sizes and of course, window screen. Using these, can I screen my ingredients to the appropriate size for gritty mix? for 5-1-1? If not, what size screen do I need and where do I get it?
The pine bark (bagged as "Organic Pine Bark Soil Conditioner") varies in size from dust to 1" chips, but for the most part it's thready, not nuggets, with 1/8" x 1/2" being typical. Also it comes out of the bag brown/black and moist, with an earthy not piney smell and dries to chocolate brown, no smell at all. I was told it was "aged". Is this the partially composted stuff? If so, can I still use it in the gritty mix?
The Oil Dri (can't find Turface for love or money) also varies greatly from 1/16" to 1/4", with most particles tending to the smaller end.
For the stone I found the real deal, Gran-i-grit grower size.
So, which of these products need screening, what size to I want to get them to, and where do I find screens if the 1/4" and/or the 1/2" aren't right?
If it makes a difference, I plan to use the gritty mix in larger pots (5 gal or larger) and the 5-1-1 in small ones all the way down to quart size.
Thanks for being patient with the newbies!
