I would love to see pics of holes in sides of containers.
I just spent all day, 200 miles of driving to several gravel/sand/quarry places, big box stores, and nurseries. Didn't find a single source of nice sharp horticultural sand. Closest was some "crusher fines", at one place, but even that had maybe 20% material good, the rest too big or to small. I was tempted to ask "where is the aisle with PR-Giants brand custom manini brand coarse sand, patent pending, 10% discount offered to bananas.org members"???
I need enough "whatever I end up using" to fill around a dozen 25 gallon pots. Spending a few hours this weekend in a stream, ending up with maybe 3 gallons of nice stuff, is the reason I'm looking another source.
