i agree with the depth of bags and water holding at the bottom. my roots had progressed down to the bottom bc i poked a few extra holes with my finger an di could feel the roots all over it.
i think for my watering/feeding from here on out, i am going to make sure i dont saturate them an di will water them more frequently. watering them just enough to ensure the water makes it to the bottom of the soil, but not too much where it gets soaked ad sits.
the extra holes also helped a little bit with airflow and drying the lower portion of the bags for me.
should i move on to a different kind of pot? i used the bags bc they fit and work best in my set up. rectangular 2x6x6'(to lights)
