POWER BILL for indoor setup

How much more is your power bill each month when running a grow tent with lighting?
Looking at this 3000w https://amzn.to/3ypdWrH

Looks like 375 watts. 375x18 hours=6750watts
Or nearly 7kwh if running it maxed all the time through veg.

Or 375x12=4500 or 4.5kw for flowering

Plus a couple hundred watts for fans, maybe another 300-400 watts for humidifier/dehumidifier.

Cost of electricity is different from city to city and plan to plan. Provider to provider. You’d have to inquire with your electrical company.


Did some research. Looks like 11.08 cent per kw hour.

There is probably a better choice for a light @dbrn32 @BobbyDigital @Nicky Amazon reviews should not be trusted


You will spend more on replacing that light after a grow or two than on electricity. You will spend more upfront for a better light but you will not have to replace it. I have a King 125w (actual) if is fine for what it is and what I wanted it for (small area veg light).
Additionally, no way will that 375w flower a 5x5 area. Maybe a 3x3.
The PAR maps on amazon look impressive but they leave out the size of the area. My guess it is a 24"x24" square. Less than honorable. For comparison only, these are the PAR maps for spider farmer 4000 with 450w


So tell me more about your light, or a better light that this Amazon light

What size grow tent?

Many of us regret having bought one of these Amazon lights. Be sure to get a light built with Samsung LM301 series diodes.

Cost me about 150to200mo the for about 2200w of light shit ton of fans ac units dehumid 2 8" inlines 2 4" inlines 1 6" online I have 2 rooms and a tent all hlg lights steer clear of the pink purple lights.

My grow cost varies month to month, based on outside environmental conditions. Sometimes I have to run the dehumidifier more often, and sometimes I run just lights. Costs me about 30-50 a month to run two tents. Dehumidifier uses more juice than anything I have.
