I heard from Zachary Evenson at: Albany Hydroponic Gardening 541-791-1006
This is what he has to say:
Anything I don't have in stock I can order, though I have to order in a case. I do offer a 10% discount on anything I have to order.
Size Number MSPR
6x4x36 9 per case 81.11
6x3x36 12 per case 81.12
8x3x36 12 per case 105.38
12x3x36 8 per case 105.86
9.5x8x4 16 per case 78.73
I can also get Pargro rockwool that is made in the same factories as grodan.
Size Number MSPR
6x3x36 12 per case 60.67
8x3x40 12 per case 89.94
I ordered 2 of the 8x3x36 slabs for $9.65 per slab. Can't wait to get started on my project.
