I love Smart pots for soil or even full of hydrotron,No issues at all.
Just dont sit it in another pot to catch runoff,Cause the roots will grow
RT thru too the runoff water.From experience learned the hard way plant
was looking weird so after taking it out it had Roots 3ft long in bottom pot,
sitting in the runoff water.
It does do as claimed as far as self pruning,and no root circling if its set
on a hard surface.
As far as watering it does drip out of the sides,But thts just fine great aeration
Allowing more oxygen to the roots.They do seem to need more water as some
imo evaporate alot.
I was using a 3g and was having to water almost a ltr a day at the growth spurt
of Flower.
When done just put in the washer and wash.
