my temp has not exceeded the 80.0-80.2 range within the last 12 hours. I didn't notice the fan operating at all after the MH had been off. when the MH is on, the fan turns on and off about 15 times an hour. this next payday i'll buy what i need to hook up the RK2 to my computer so i can upgrade the firmware. i'll then be able to log and graph my temp and pH. it will be interesting to see how this system performs in the peak of summer. i imagine i will have to turn up the speed of my fan. if that's not enough, i have a safety cut-off for the MH light set.
