Roots LOVE coco....
I agree with you that a porous light weight medium will allow for better root distribution, and more root space, but it all depends on the composition of the soil, or whatever medium you use.
I use both coco and BioBizz All-mix, which technically is soil (20% sphagnum peat moss, 35% garden peat, 10% organic Worm-Humus, 30% perlite and 5% Pre-Mix), and it's clear to me that I get slightly more impressive plants in the All-mix than the coco, as well as slightly higher yields, and less ph issues.
I still mix coco into the All-mix though, because of better water retention than the All-mix, and I love coco as a medium.
I just have to say things the way I see it, in my garden.
