Electricity bill came. Mind my poor usage and understanding of Kilowatts and its abbreviations.
examples of math using 100 watt light
24 hours x 30 days = 720 hours / 1000 = .72 kilo hours x 100 watts = 72 kWh kilo watt hours
18 hours x 30 days = 540 hours / 1000 = . 54 kilo hours x 100 watts =54 kWh
12 hours x 30 days = 360 hours / 1000 = . 36 kilo hours x 100 watts 36 kWh
Let's assume my setup uses 320 watts per hour then:
<total for 30 days>
24 hours x 30 days = 720 hours / 1000 = .72 kilo hours x 320 watts = 230.40 kWh /30 days = 7.68 kWh per day
18 hours x 30 days = 540 hours / 1000 = . 54 kilo hours x 320 watts = 172.8 kWh /30 days = 5.76 kWh per day
12 hours x 30 days = 360 hours / 1000 = . 36 kilo hours x 320 watts = 115.2 kWh /30 days = 3.84 kWh per day
So.... Tier 1- First 323 kWh cost $ 0.15 per kWh
for example $ .15 x 323 kWh = $48.45 if used 323 kWh exactly, but if used say 400 kWh, that would be if you ran 1000 watts x 400 hours
the 2nd tier is for the next 97 kWh and cost $0.17 each kWh from above 324-420
for example .17 x 97 = $16.49
for example if 420 kWh are used would be tier 1 and 2 combined to be 323 + 97 = $48.45 + $16.49 = $64.94
then next 150 kWh were $0.34 each from 420-570 kWh
$.34 x 150 kWh = $51
Last Tier= every kWh after 570+ that was $0.36 x (hours used above 570). Not cheap that is for sure. This is not exact but pretty close to what I saw and from memory.
I'm going to do a little estimation of what it costs to run some of the things in my setup.
My 200 Watt light .200kW= .220 kW (10 percent for loss of energy, it takes more than 200 watts to power a 200 watt light, say 216 or so, I'm just estimating at 220 watts.
.220kWh x 24 hours x 30 days = 5.28kWh per day x 30 days = 158.40 kWh for 24/0 lights on each day everyday of the 30 days
.220kWh x 18 hours x 30 days = 3.96 kWh per day x 30 days = 118.80 kWh a month just for the light 18/6 during veg
.220kWh x 12 hours x 30 days = 2.64 kWh per day x 30 days = 79.2 kWh a month or around 80 kWh a month during flower
Can fan RS4HO-Max 78 watts
Air King 6 Inch Clip On Fan- 9 Watts on Setting 1, 13 Watts on Setting 2
Speedster wattage?
Total of fans+speed controller
100 watts per hour with use of fan controller and all of fans so if you have them running on 24 hours a day
2.4 kWh per day x 30 days = 72 kWh per month for fans and speed controller
120 kWh (lights) + 70 (fans) = 190 kWh (total with lights and fans per month at 18/6 veg )
80 kWh (lights) + 70 (fans) = 150 kWh (total with lights and fans per month at 12/12 flower)
190 kWh = (30 days of veg)
150 kWh = (30 days of flower)
190 kWh x 2 (for 60 days of veg)
+150 kWh x 2 (for 60 days of flower)
340 kWh for 4 months total veg and flower (this part won't help for figuring out cost, since it's calculated per month and by tiers anyway, but ya)
I have my exhaust and circulation fan come on and off every hour when the lights are off, run for an hour then they turn off for an hour, turn back on for another hour, repeat until the lights come back on, keeps humidity down and helps airflow. I think it should be on all the time though, but I'm trying to conserve my carbon filter's life until flower starts. I dunno, my first time with a carbon filter and super good fan I am trying to quiet the fan down, so I ordered a phresh duct muffler and can't wait to see how that helps.
