Grow Room Grow Tent Power Consumption

[jdot]

I have been curious about power consumption of my environment for a while now. I picked up a smart plug from amazon and have been measuring the various components of my setup. I was surprised at how little power I was actually using.

Are these plugs accurate? I have a 2 x 4 x 5 tent btw...

Nice little chart there

Nice homework. The meter should be in the ballpark, more than good enough for a realistic picture.

Power costs for a small grow with LEDs is very reasonable when compared with the bud produced. I was pleasantly surprised when I went through the same arithmetic.

The voltage drop you are getting to the small fan and cobs is a bit of a puzzle to me. Did you add the loads as you filled the table from top to bottom? Was the voltage measurement at the single wall plug supplying the whole tent?

I used a single smart plug to take the measurements and measured one device at a time. Basically I had the smart plug plugged into a power strip then I would plug each device into the smart plug and read the amount of power it was consuming and then move it back to where it was plugged in originally.

So everything was plugged in to the same power source during all measurements, but only one thing into the smart plug at a time? If so, even more of a puzzle to me. Probably no biggie, but puzzling. It wouldn't hurt to double check for plugs or extension wires a little warmer than expected. You are using up a few watts in the wiring setup somewhere.

Good luck with the grow.

$15 a month unless you live in Hawaii?

Currently I am running ~650 watts day 50 w nights 12/12 the hourly average is a 350 watt hour x 24 hours = 8400 watt hours or 8.4 kW-h x 30 days 252 kW-h per month. My average electrical use for the month is 1000 kW-h so my grow is 25% of my fixed utility bill (solar) $50.

It really sucks if I have to turn on the dehumidifier that thing pulls 500 watts. These numbers are all different for Autos on 18/6.

@Olderfart my line voltage from the utility used to range from 110 to 120 since the installation of my solar system I do not see any or at least I have not logged any.

I calculated for 18 hours a day 30 days a month using the 240W QB and added a little bit for the fan. I currently use an oscillating fan which is only pulling about 35 W, So it probably cost me around two dollars to run it 18 hours a day for a month. 10-11 cents per kw hour down here.
