I use hard plastic pots. Round in bloom, square or round in veg.
I don't use fabric pots. Others do, and some of them have tremendous success.
Hey Doc! been a minute since I swung through! and see you didn't skip a beat... actually skipped a lot of beats.. in the hearts of your observers! haha those plants are looking epic as usual!
Question: any theory or reasoning behind using round in bloom, square in veg?
