I have been curious to see if the pot size really makes a difference? Is it possible for it to do more harm than good if the pot is "too big"? Reason I am asking is I am getting ready to repot most of my plants into the famous Al's gritty mix but I didn't know if I should buy a couple smaller pots for my smaller pots or larger pots for my larger plants. I don't have too many to do but was told once that on my money that I have I was told the pot was too big for it. I am also concerned that a jade plant I recently received is in a pot that's too small for proper growth. Any and all help will be greatly appreciated. Thank You
