I have done side by side grows with plastic pots and fabric pots, both indoors and outdoors using identical clones and have seen very little evidence suggesting fabric pots are better for the plant.
BUT, plastic is killing our planet.
These plants were vegged for 2 weeks (indoors) as there was only 8 weeks of the outdoor growing season left. Hence the almost SOG like single flower colas. Some pulled slightly early due to late April rain.
Meaning the plant looks good. Leaf is green. Stems are green. She looks healthy but I am afraid that she will not stay like this....I say this because I can see lots of wood bark in the soil. Wood bark in its current state is crap, it needs to break down and decompose before adding value to the soil. At the moment its just acting as a medium to hold roots together. There are better options out there.
