What did you accomplish today?

I have R-19 in the walls of a 6X6X8 room in a garage with 11" of batt insulation on top. Heat is my biggest challenge.

What's it supposed to be 18w?

Is that white wire for PWM or is it tach? If it's PWM, when disconnected the thing should run at 100%

What voltage are you getting at the pump?
10W, giving it 12V off a 5amp switching power supply. I believe the white wire is for pwm, mostly because when I got the unit I was looking for a pwm controlled pump, didnt think about it being a tach wire that would require seperate voltage regulator cuircuit to make it pwm compatable?
I tried putting more load on it but couldn't distinguish anything above background fluctuations.
Dosen't ssem to be a big issue cause there are two pumps in the circuit and temps seem to be well controlled with only one pump running. Included it because I was worried the long run of tubing would be too much for the pump that is on the radiator.

Yeah if that white wire is tach, you can hook up your multimeter and use the freq counter to see what rpm the pump is running at.

Also, if it is tach, you can control it with pwm no problem:

Don't forget the diode.

Checked trichomes and found PM on a few plants. On big gelato, a kosher Kush, a dragon fruit, and the sour D with the most. Looks like they got started on the sour d and spread from their. I carefully disposed of all affected leaves. If it continues to spread then I just might be back in trim jail sooner than anticipated. Everything is mostly cloudy trichomes, some plants with 50/50 cloudy/clear. Works for me.

Picked up the small Xmas tree stand from my daughter for the small tree she picked up for me. I was going to activate my prescriptions on base but the clinic is closed the first Wed of the month for "training", which I forgot about until I drove out there. Made a blinder for the seedlings so they won't get any light from the room when the lights are off. Still tweaking the fan/heater in the grow room, getting closer to the temps I want. Buds and suds time.
