I've seen that in stores. I was tempted to try it, but I decided it was just too big for my 5-1-1 tastes and passed.

the bag was too big or the actual perlite chunks were too big?

Chunks

HD sell a big bag ( one cu-ft ?) for $26 .

I think big bags are usually 2 cu ft.

Big bags are usually 4 cubic feet.
If the chunks are 1/4 - 3/8 of an inch on average, it should be excellent! I'd love to find some of the chunky stuff...my source dried up.

I use #3 horticulture grade. it is very coarse and has very few fines.

You are right, Oxboy555. I was WRONG twice , both on quantity and price: SORRY !

I bought a bag today.
Now I am ready to brew my version of 5-1-1
