Hi mate I use the a.I.t spider I use a toothbrush and then get a needle and poke holes all the way threw. Listen I don't worry about the rez temps to much . I know if I keep my room temp at 24-25 and never had a problem I learnt a long time ago from a master DWC grower that the more oxygen (very small bubbles) your getting to those roots the better I use 1 double tube Ait spider and 2 50m golf ball air stones in each pot. I use 2 120ltr a minute hailia premium air pumps and I grow 10 at a time and I haven't checked my rez temps for a long time. Just keep YOUR room temperature at 24-25 and you will be sweet.
