What are the diameters of those BG beds in the last pic?
I think I will order a "mixed" load of gravel - some pea size with some "oversize" Try to get the pea gravel in the BG beds, and put the larger stuff in several spots with and without tires. Most of my clay is not covered with silt so I should do ok.
Eric you made me feel guilty asking for help without first doing a simple search. Thanks for your patience with so many of us newbies. I did a couple of searches for "gravel" and "substrate" and found those 2 you pointed out and some others.
I will try to be more concientous and search first before asking. Your constant help is much appreciated.
