Cogr is a dry slab in a black-white bag, maybe 1 meter long. Ready to drop in trays and expand to fill them. Slash the plastic and populate.
It's consistency is like the bigger bits people often sift out of other brands. It's chunky and fast draining. I'm able to take it out the bags and fill 2.5L pots, at about 10 per square meter. That's 25L of substrate per meter, coming in dry and compressed. I forget the weights at run-off and watering time, but getting that 6L of water to them, meant watering many times a day. So there was a good air exchange through displacement, using a feed from a well bubbled barrel. Taken to the roots regularly.
High frequency watering produces real results.
The Pro gets a lot of use. 40L per meter requires a daily watering. Though in peak times, you could offer a little top up. I have had to start washing it for rooting cuttings and starting seeds though.
Normal coco.. I'm about to try it. I'm treating the Pro anyway, and you only buy Pro because it's meant to be done. I'm just wasting money I think.
Other brands have been poorly treated or not had the water capacity that works with my systems. I don't really have time to learn another brand then build a system to make it work. It's expenditure that would never come back. I did for the Cogr because it is a very different consistency, and I knew it would pay off. Most coco is just coco though. It's really not somewhere I'm looking to find gains.
