My root system: looks good or bad?

The entire fabric pot is a mass of roots by the end of a grow. I have to pull and pry to get them out and it's a pretty solid, pot shaped mass. I would say you did not reliably water/moisten the entire soil mass. Roots will go where the water is so you have to be mindful to soak the entire mass of soil. In your case I can imagine that the area you watered is where you have roots. The top and bottom corners and even the sides look like they did not get enough water.

Thanks Roberts - the one I am showing was quite disappointing, hard grow with low Yield. The roots system looks good comparing to the flower performance….

Roots look great. Sure there was more finer roots that broke off. Fabric works great for helping roots become more complex. Using a root inoculate will also improve on roots if you are not using one. Congrats and good job 🌱🌱
