Power Consumption / Light Cost

for maximum yeild on 30-35 plants...a lot

I just started running a 1000w hps with mh bulb 20/4...hope it doesn't jack up the electric bill too much...since I started using it I stopped using the heat though, I rarely turn on other lights, and I unplugged everything unnecessary, great temps in the grow room... boy its been chilly in the house though. Came out of my room yesterday and my roommate was eatin cereal with a jacket and ear muffs on...what a pussy

hahaha @ eating cereal with jacket and ear muffs....


kodak moments!!!

yeah i had no idea growing would be so fun and consuming at the same time, I'm lovin it even though I had to go from sleeping in the buff to sleeping in sweatpants and a sweatshirt and seeing my roomy eat breakfast in his winter gear

so let me get this straight.

my bill says (over 1000 kwh at 0.06227) so is that an hour?

say we are running 3600watts. for 12 hours a day.
would it go like this?
3600 x 12hours = 43200 divided by 1000 = 43.2 kwh used
now 43.2 x 0.062270 = 2.690064$ day x 31 days = 83.391984$ month.
hmmm seems very cheap doesnt it?

you rural people got it made. IM PAYING 15 cents a kwh. im holding my bill right now. 1100 kwh last month.

but are we telling the whole story here.

theres a delivery charge

theres a sbc/rps charge.

theres a sales tax charge

actual electric is far less than what i pay, hell i spent 60 on the delivery charges alone untaxed
and my bill is 250 total to reference.

Can anyone take a guess at how many KW/h per DAY you can get away with without sending alarms ringing?

Lets say we have 6 1000watt lights going at 16 per day, thats 96 kw/h in a day.
thats about 5-6 bucks a day = $150 month.

Do you guys reckon that you can get away with 12 1000 watters?

I am planning to make a flowering room out of an entire basement.
Probably an area of 16'x12'.

I'm looking to dedicate about $500 of electric bills a month to growing only.

Is that the kind of figure that would raise eyebrows?
I live in Canada, Ontario by the way.

12 1000 watters! !

gotta go back home and change my pants..

fuck...not again :/

You're going to burn your house down.

I worked out the total load of all my stuff at just under a Kwh which basically means a 400w 6-8 plant Hydro/Aero system breaks down per day @

400w HID 18/6 = $1.23
300w Main pump 15on 15off (12hours) = 61c
10w Circulating pump 15on 15off (12hours) = 2c
10w Air pump 24/7 = 4c
120w extractor fan 18/6 = 38c
38w circulating fan 24/7 = 16c
38w intake fan 24/7 = 16c

So thats $2.60 per day to run it all add in wastage factors of appliances at about 15percent and you have $2.96 per day 6r $20.72 a week or $331.52 for a 16 week grow.

So 1oz covers electricity costs if you were ever to sell! nice!

about how many 400 w hps should i use for maximum yeald on 30 35 plants roughtly

They say 100w per plant as a guide, you can get away with 4-6 bushy plants under a 400w if you train them a bit.

personally I'd go with 600w, almost twice the light output for half the extra cost in running.

I have 4 very nice plants roughly 6 weeks into vegitation, I need to get some HID's when the time comes to 12/12. Will these work?

I, also, am really interested in this topic. Please correct me if I am wrong, but, we do not seem to have had any feed-back from anyone that has grown that has used this means of lighting. If it can be utelised I do think that it will be the way to go. Even if techo does have to catch up . . . c'mon techo!!! Go you little beauty . . Anyway . . . please . . some feedback some daring sole (head?) out there.
Youse all have a good time out there . . . by order of George B. Yah hear that?

maybe search doesnt show them but theres been a few led threads on here. Theres been a bunch on the internet.

LEDS WILL NOT GROW SMOKABLE WEED.

YES YOU CAN START A PLANT WITH THEM BUT SMOKING AN ENJOYABLE AMOUNT OF WEED WITH THEM IS NOT POSSIBLE AT THIS POINT IN TECHNOLOGY. LEDS ADVERTISING 100 REAL WATTS EACH IS THE POINT I THINK IT BECOMES FEASIBLE.
DONT WASTE YOUR BRAIN ON TECH THAT IS 15 YEARS IN THE MAKING TO COME OUT AT PRICES THAT MAKE IT REALLY 25 YEARS.

okay i was looking on here a couple of days ago cuz i was looking for light costs and it led me to this page. So i found a method and tryed using in and my ending prices were WAY off, so i dont kno who it was but he was wrong. but i did find another method that helped me so i thought id post it to help others.

• 400 watts x 24 hours x 30.5 days = 292,800 Total Watt-hours
• 292,800 Wh / 1000 Wh = 293 kWh
• 293 kWh x 10¢/kWh = $29/mo.; $351/yr.

I live in michigan and last months electric was 789 kwh and the bill was 84.44 so in my area its roughly 9.34 cents a kwh. Do the math problem ubove on a calulator so you do it right and then use ur watts and price to figure it out.

anybody heard of the 'eliminator" or some such product that u plug into your breaker box and it some how back feeds, or confuses the meter thereby reducing your bill? friend told me about this, don't know if it is bullshit and can't find any info online?

its not confusing the meter or changing anything other than efficiency. ballasts waste energy in heat and other defects. Those boxes basically handle electricity better. So if a ballast took 1kw it may use 75% of that for you. Those add on boxes make it so its using 100%. so it takes less electric to run it cause its using all it can get and costs less in the end. But for 500-1000 that they cost ive never bothered to investigate firsthand and dont think the 5 bucks a month youll save is worth another device/ fire risk being plugged in.

too much expenses for no reason my girls are growiing on 45watt flourescent nd strong healthy , beautiful

I need my amperage uprgraded in my house everytime i have a couple things on at one time the circuit breaker blows...do i call an electrician,or power company.....or both?
