Thoughts on sure to grow growing media

Does any body have any experience with stg growing media? Just wanna get some opinions and insight on the stuff.

to many problem like water retention, they have bugs to work out yet with that product

what do you mean my that. i've seen the vids and it seems like it does pretty good at holding water without under or overwatering

It's 100% plastic/polyester so I don't like the idea of it at all since it's totally non-degradable. It could never be backyard composted like coco-coir, or even mixed into soil like perlite, only into a dumpster.

But I suppose that's true of rockwool also, yet at least rockwool isn't plastic.
