@DCLXVI I think the eazyplug people don't care about the weed market, they could if they wished really shake things up.
This morning I noticed a heavily furry root poke out from my Jack47 in the cube, which is like a solo cup. The root is completely covered, however when I watered the plug I notice that all the superfine fuzz was washed away. This is why I think these plugs produce such high quality in a small space. Just a bit of water tricking past wiped ALL the hairs off the root. So in soil, every time the bag moves or water flows through it's going to do damage to the business end of the roots. And that to me is a satisfying explanation of what makes this so good and why there's nothing else like it. To make up for the damage that normal soil in fabric bags does, the root mass has to be at least 4 times the size.
