Well, IF you are growing for your own use and not to illegally resell, then your electrical use really shouldn't be an issue at all. I mean, unless both of you do nothing else but sit around all day long and smoke gigantic Cheech and Chong size joints, and your personal use is…let's say…"discrete"…. and
not "about a pound" per month (lol…inside joke)...then your electrical use will not be that great.
I like to start my ANNUAL seed-run of 6 plants (max) in September and allow the plants to veg through November. That's when there are fewest bugs flying in the air and also when the day/night temperature differential is the widest. Then they flower for up to 120 days -usually have everything down and in jars by the end of February. This amount, grown well, can easily last me through the year -easily!
This timeframe also coincides with the furnace being on more and longer hot showers in the morning….more "oven baked" foods because of the cold, winter temps….So, basically,
everyone's electrical bills go up around this time for the same reasons….unless you live in Florida or something!
And it's also not like there are government spies watching for high electrical bills, anyway. Just pay your bills on time; Don't be a trashy neighbor and attract attention to yourself in any kind of bad way. Don't have parties. No loud music. Don't have lots of "friends" coming in and out of your house all day and night….Etc. Keep your lawn mowed. Don't sit on your porch in a tie-dye shirt, smoking and "advertising" that you are a head. Present yourself and your property in a "non-pothead" kind of way. If you become the neighborhood "suspects" by way of inviting trouble to your door…and you're in an illegal state…then , well….you'll learn the hard way.
The best advice I can give you id to move to a legal state and do your thing. Barring that as an option, you just have to be really, really careful. But your electrical bill shouldn't be a problem -unless, like I say, you're trying to create an illegal drug-dealing operation and growing a lot of plants and using a lot of electricity in the process.
