Just one more thing to add to the copiapoas thread I started and that is right now both are in 4 inch round pots which are 4 inches tall and have been in them for some two years now, and I wish to transplant them into square tall 14cm pots but want to someone to help me what would be the next size equivalent to the pots I have them in now. If I have them in 4 inch round pots what would be the next sized square pots?
I know for a fact that you should put into pots that are too big.
