Hmmm interesting, Ive been using air pots for the last few grows and yup, they are superb. Good air flow all round. Bit of a pain to water cos it comes out of every hole! but....managable
But, what you said about having the bottoms in the wrong way round has interested me. I cant remember what way i put mine round now! lol I think i put it the right way round but not sure now, you havnt got a pic of the correct way have you? Im sure mine has a 'nipple' in the middle and i always put that sort of pointing downwards if that makes sense.
Anyhoo nice pics, looked just like mine when i 'peeled' off the pot after a chop chop.
If you have that nipple facing down,there in there right.
