The 5.8L Anti-Spiral plant pots are already available in Alchimiaweb, designed to avoid the spiral growth of the roots while enhancing their development and performance. Made of black plastic.
The side slits of these plant pots force the roots to change their growth direction, thus preventing root bound. Moreover, they greatly promote root branching.
The large drainage holes at the bottom of the pots ensure sufficient draining and avoid waterlogging.
They measure 24cm in height, 19x19cm at the top and 15x15cm at the bottom. If using the SOG technique we'll have up to 25 pots per square meter.
These pots are used with the 18cm square saucers.
