Amazon has 2 possibilities and one says premium coarse (27L for $38)
Why does everything cost garden-related cost over four times as much up there in Canada? Is it entirely because you legalized cannabis? Seems a bit unlikely on the face of it,
but...
When I called in January, guy "up the road" at the local nursery said he was probably going to have to raise the price of four cubic foot (about 113 liters, I think) up from $30.something to $37. I thought that was pretty high. And that's USA dollars, not diet-dollars (loonies -
less filling ).
Man... We need to figure out how to set up a smugglilng ring for gardening supplies. We'd be rich, RICH. Cars, boats, store-bought food & tobacco...
EDIT: Here's what you need to do. Get a sheet of cheap plywood, cut it and put it together in the shape of a box. Cut a big circular hole in the front of it. Stick the thing in your car's cargo area (or back seat). Drive to the border. Keep right on driving. When you get to the land of cheap gardening supplies and expensive doctors, slide in to the first greenhouse/nursery you come to.
NOT An "Indoor Gardening Shop," "Hydroponics Supply Store," or "Dope-Heads' Paradise" - the owners of those kinds of stores probably mark their products up about 300%, because why wouldn't they, LOL? Walk in and ask for some four cubic foot bags of PVP Industries coarse sized horticultural grade perlite. Take them out to your car, open the bags, and dump it all into your box. Then, throw the empty bags into the nearest dumpster and drive home. If you get picked for a search at the border, complain about the crime in the USA - and point to your "speaker box that someone stole the subwoofer out of" as an example
. They'll assume that all the perlite is the crap people fill their speaker cabinets with for some sort of acoustical purpose and, instead of trying to make you pay a fee for importing perlite, will just laugh at the unarmed visitors who got ripped off. But you'll be the one with the
reason to laugh. . . .
