air stone question

is fresh air in the aero cloner necc?

What do you mean by fresh air? Your cloner should be fine with no airstone.

an air pump with air stone, If u never open the lid no fresh air is getting to the roots. this shouldnt be an issue?

i use a air stone and liquid oxygen but im in a nft system never dun aero but a air stone aint gonna do no harm mate

well i was told that u cant do aero cloner UNLESS you have air pump with fresh air in the res

i wouldnt of thought that you must have one in but in my opinion i would have it in res from day 1 its not as if they eat up the electric and they are not expensive.
good luck.
