Ventilation in tubs

[Snakelove]

Where do I put holes in tubs for ventilation? hot side or cold side? i always thought itd be more holes on the hot side coz hot air rises and it needs to escape otherwise it'd be too hot? or do i just put it everywhere evenly? thanks!

Try both sides

everywhere evenly.. that way the temps will be even just a few degrees lower..
