no problem, i`m glad to help.
the only noise i get from my cabinet is air movement noise
the fan i use is quiet running, but the air moving out is what makes the noise
your temp. is a bit on the high side, the flower chamber temp isnt too bad but your mother chamber temp seems awful close to maximum. you may have problems if it gets any higher.
my cabinet has 3 timers, one for the fan, and one for each light.
i have it set up where the fan comes on a few minutes before the lights.
my maximum temp on either side is no higher than 78 degrees farenheit
if you got more questions, just ask
by the way, is your cabinet built with the pvc elbows and such for air intake and exhaust?
