I wouldn't use that in a container mix necessarily.

It says it's a mulch, and it's colored....which might present some issue.

newgen, coconut coir or coconut fiber is similar to pine needles and does not expand when wet. I'd say that it is water-proof.
I suspect that the advertised product contains other components.

I bought coconut coir as Mulch Bricks to mix into my veggie containers a few years back because they were cheap, I thought they might help with water retention, and I believed the hype about how coir was better to use than peat. The small brick did indeed expand to two cubic feet. But the chunks were 1 to 2 inches in diameter, and I don't believe they helped with drainage because my other soil components were so much smaller.

Also, I would be concerned about the fact that this stuff is "colored." unless the label says it's safe for use on veggies, I wouldn't use it on anything you're going to eat. I also understand that coir can contain a lot of salts.

Now I am using Al's 511 mix with pine bark fines. They are actually cheaper and have worked very well for me. Check the link if you want to know more.

Since coconut oil became a dietary No No, I suspect this industry took a hit. I think they are likely looking for new markets for coconut, can't fault them for that.Coir pots don't have the body to make good containers for me, cheap as they are.
