Ok, so I just piled on more claystones around the bottom of the plant. The roots don't grow upwards anymore, and the plant seems to be more stable in the netpot. It was a little tipsy before. I have see hydro setups where the roots completely overtook the hydroton on top, tons of roots sticking up from top of the netpot. And actually, plants roots do grow horizontal sometimes. That's why u find tree roots two times the tree length away. Because the roots are growing outward so the topheavy tree is stable. And my plant is taking over my grow room, so I'm obviously doing something right. And the plant is very topheavy. So for it to grow an extra amount if support, its sending more roots out to explore... It makes perfect sense...
