I'd go for Air-Pots if you have the cash, that bit sturdier.
But if you're hard-up for mulah they're definitely better than ordinary pots. A great place to start.
I heard that the fabric pots were better than the air pots. I'm still very limited in what I can do because of a family situation but I will be able to try some big air pots later this year.
I found some good ones (fabric) on Amazon and am awaiting arrival.
My only available space is a cabinet about 800mm high so have gone for 3.4Lt
@captain beefheart, I usually like to water from underneath, will this be feasible with fabric pots?
