Power Consumption / Light Cost

I love it when people, and that includes everyone in this situation, assume they know what electricity costs others.

I've spoken to pge told them my wattage for 12 hours and the above number is on average CORRECT!

YES IT SUCKS!!

Check out the below link and you'll see why my rates are so high I'm at the highest rate surcharge when I use my grow room. My city has almost a 10% higher electricity rates in California and California has a 40% higher rate than anywhere else in the country on average.

Here bro, enter your $.50 per hour rate

Go ahead and argue with pge because that's who bills me!

I know what I get charged and I know what watts I use. Ive had this same argument on another forum.

I'll leave it at that.

SDG&E loves to tell me how much more energy I use than my neighbors.

Fuck 'em! I can say that my costs are about $100 extra a month.

Get yourself a smart plug and you'll find out exactly how much power your using per day. I have one by meross which shows current consumption as well logs historic usage. Its ~20 aud.

My flower lights use 17.28Kw (which actually works out to what i expect 480w x 3 x 12). You can assume a linear power consumption so per hour I am using 1.44Kw per hour.

My peak cost is (all AUD) 38c per hour and off peak is 19c (thank your 2 decades of successive energy policy fail Australia) so starting at 12PM and finishing at 12AM I've used 1hr of off peak and 11 of peak (i have solar power so my economics are more complex) so I'm spending $4.37 every day on flower lighting. I'm doing 10 weeks / 70 days so it will cost me $305.9 in electricity to get to harvest.

My energy retailer also likes to tell me "your using the same amount of energy as a family of 6!". I tell them "I do science" lol
 
My god. I figured it out for last year. My electric bill was thirty thousand for one year. And we gave away everything we didn’t smoke ourselves. And I didn’t really grow that much I had about 22 plants in flower . Ten or so 315 watt lamps , an air conditioner , ten or so fans water bubbling constantly. My bill went from about 350.00 a month to about 12 to 1500 a month. But it’s all for a good cause. Vets and patients who can’t afford to go to dispensaries. Fuck it. #moreweedlessgreed

20 x 20 room ten to fifteen lights in there. 315s KICK ASS . Veg room upstairs with 2 600 watt hps with one 315 in the middle.
I guess it gets expensive to run all this shit. Ha true story when the electric company called they said Um sir your electric went up about 2004% from this time last year. My reply was

YES ON 4 woooohoooooo that’s weed growing in my cellar not someone stealing electricity. Yes on four baby.

Have you tried measuring out those lights with par meters and setting them up as to provide the most illumination with the least amount of electricity? I did this my self with a 15 plant operation and I was able to take down 2 of my 600 watters and keep the needed par. Needless to say, it saved me a ton of money. I ended up taking it down and just getting a nice sunny area for outdoor grows. That saved me even more. Now I have one plant I work on indoors to send in for contest and the outdoor area goes to the patients.

Ohms law is relatively straight forward and can be used to calculate an accurate figure of wattage useage from any light system, and this would probably have been a better way to go. To calculate total wattage used from a ballast HID system you need to use the amperage figure not the bulb wattage figure. To show you how your figures are inacurate, OHMS Law is Volts x Amperes = Watts, so if we know two of those figures we can calculate the third.

The real wattage of a 400w HID system is Volts x Amperes or 120 x 3.8 = 456watts for an average 400w system others would be -

250w 120 x 2.5 = 300w
400w 120 x 3.8 = 456w
600w 120 x 5.7 = 684w
1000w 120 x 9.5 = 1140
Does that mean a phantom 315cmh running on 240v is 240 x 1.5 = 360watts?

i suppose mine is cheap comparing you guys. i pay .11 cents a kilowatt/hour. 1k light x 12 hours = 1.32$ a day. (i included taxes an shit from my bill to get .11 cents. )

Did they have the cops come pay a visit or are things working out?

I run 600w LED + 150w HPS + 5 fans + window A/C and it raises my electricity by about $50/month. Without the A/C, about $20 more a month.

I run for about 1000W of fans, 2 X 1000W MH/HPS (in process to upgrade to LED) a 8000 btu AC for the root zone, so im about at 3600W and i pay 6.29c/kw/h, problem is in alberta we get so much administrative charge that is 50% of my bill, last month i was veggin 16h a day, my power bill for a month...
