i have a flouresent ligt about 3'' from my baby plant will it burn the plant

I don't know if it's been added or not. But depending on where you live you're going to see an increase in your delivery charge as well. It wont really set off the authorities, but it's just something to take into consideration when budgeting your costs.

If it really concerns you try switching to led's

quick question for anyone that can help.
I've calculated my power consumption to be about 3,500 kWh/month.
I live in a 2000 sq. ft. place, i dont know what that has to do with anything, its a 3 bedroom.
Is this enough to raise some eyebrows?

Depends on what your baseline is really.

That will be a huge amount if you have a smaller or older home with a low baseline allotment, but not so much with a bigger or newer house or a house with a pool you can shutdown, or something of that sort.

One way to see how obvious it will be is pop open your breaker box and see how much juice you have coming in on your mains. 50A-100A is low for something like your talking. 150A-300A would be plausible with an empty/very unused house.

Usually 1kWh per bedroom per month is the "norm". Depending on the economic class of neighborhood you live in could be suspect.

Yes it will raise eyebrows.
It's more than 3X the monthly average of 920kWh.
Stealth is the name of the game:
Don't be seen.
Don't be heard.
Don't be smelt and don't be measured in excess (on the meter).

I've had good results with 60W RED/BLUE units.
