Yes. Oz = zip, nada, zilch...What's a zip? A ounce?
I have 10 plants in "root pots", and not a single one has roots popping out the side, not a single root... I won't be buying them again, only reason I did, was they were out of smart pots, and was told they are the same...Thanks for explaining.
I read somewhere that "root pots" were better than smart pots but there hard to find over here in England.
I'm not too sure if I want to go with smart pots or air pots with coco.
