Mid Atlantic most of the time, Tom. My covers are not like a Tupperware seal or anything.....lol They are just laying on top of the netpot/hydroton. About "stale air", I have none. I can make my growroom a wind tunnel if I want. I got hells of fresh air commin in, and the old is scrubbed and exhausted.

Those super fancy special plastic doo hickes they sell I have no idea about. I know bghydro carries them, but since I had some panda plastic handy, I used an empty netpot for size, cut out circles, cut + in center, and voila.

I am not cheap or nothing like that, but if I can fab something to achieve exact same result as something that would run 20 bucks, hell, I make it. Fron picture on a website I could not tell how big hole was in center either. So, I figured as my stalk increased in girth (eazy ladies), it would just push the plastic back, and it does, perfectly.

I've seen pics of all kinds of different shit used. This was just easiest and what I had materials to do at the time.
