I used to use canna pro but It always looks a bit iffy when you get bags of coco wrapped in black plastic. The delivery driver is bound to know it is soil/coco, I guess I don't like anyone knowing my business.

10 coinz (pucks) make 1 liter. 50 Liters in a box
The box is fairly small and no one will think it is coco when it arrive in the brown box. it is also convenient to store in my flat, where space is limited!
I usually add perlite 4:1 coc to perlite and was using Grow Stones made from recycled glass which had more air than any other aerating substrate.
I don't think grow stones are still around, a shame as it used recycled glass and was a good product.
Coco coinz is decent coco washed. aged and buffered!
Almost finished refurbishing my grow cab, too many plants now to fit in my 2' x 2'.
Just need to do the door with mylar and the jobs a good'un.
Here is a couple of pics.
Up top

SanLight S4W

Down low
Shiny bubble mylar
A couple of S4W's leaning at the side.
Current only have one S4W in the cab but had to order more ratchet hangers as the 300W COB now resides in the 2' x 2' tent.
So I'll add another S4W when they arrive.
