Start with one light, then add another and another so the increase is gradual and pay your bill on time and it wont' raise an eyebrow. Trade some bud for some stuff to make the cost in electricity offset.
A couple of very good ideas Bot.
DWC saing in one grow, you can get much weed, and not grow again for say three months, saving power.
instead of 20/4 or 18/6 you CAN go 12/12 or 14/10, less power, but less weed also.
or even switching to LED's When you use a 400 watt LED, it consume a lot less power than a 400 watt HPS.
You could also use flourescents, build your own so it will cost less, but cost saving analysis says it won't save you all that much in the long run.
Good luck, and let us know if you come up with

Hello AFN!
I grow since a year inspired by AFN.
I like to see here big growns, box and many many beutiful plants.
I use only 400W HPS, but this one light make my electrical bill double size...
I dont really know how do you guys can run for example 2000W grown room.
In my country unfortunately growing is not a legal thing... (,,I,, government), but as I see many grower in here in the same boat.
Can you advice me some trick ,or have any well-established process to grown with bigger lights in a bigger box? How do you resolve the bill problem?
(I means not the payment is the problem. The high consumption is the problem. I dont want to fight with the law...)

Unless you use very little electricity, there is no way a 400 watt light can double you bill. I just calculated what it costs to run my b600 watt, Metal Halide light. Based on running it 18 hours a day, for 75 days ( about the length i expect my grow to last till harvest, ) it will cost me $94 for the 75 days. I based this on a cost per kilowatt/hr of $0.12. So a 400 watt hps ror MH will cost about 30% less than that for the same 75 days. So your light should be costing you less than $30 a month. After you factor out the cost of setting up a grow room, with seeds a grow of two plants will cost you about $100 ( $60 for electric, estimate of $40 for seeds. So if you only get 2 ounces, that's $50 an ounce!! Whats bad about that?
Ahh sorry, I just saw your in another country, so i have no idea what electric costs, but still, it should not double your bill.

I made a calculation for you with online calculator.
Yes you allright I exaggerated a little, but belive me just a little.
Our bills are 60$/mounth. My 400W HPS + fans push it up to 110$ / mounth. Thats a fact.
So my 400W HPS raises 45-50$ / mounth. If I use it for 3 mounths, just my grown room use (3X45$) around 135$.
So belive me thats almost double.
If you read my question, it was not intended to my bill are big,and this not worth it for me.
I just ask how do you guys use mutch more bigger set up, in a contry where growing is not legal.
I ask it because I want to go bigger, but as you see, this 400W is "almost" double my bill, and I do not want to be conspicuous.
I only ask this, I never sad its not a good thing for me right now, so you tell else about me, I'm not complaining, not what I asked. Sorry about my english, maybe I understood something wrong, but I read it 4 times, so I hope I understand well that you say. I think it's a misunderstanding between question and your answer.![]()

Probably, I'd guess anything under 2000 watts would be ignored. Yea they'd bust a small grower, but they don't really go out of their way to do so unless someone snitches or your dealing. The money is in busting for profit grow ops. Where ever you are, I'd say your probably at your limit if you don't want to be caught. I'd say your best option is to do an outdoor grow also. Lots of ways to stealth that. :Sharing One:
I know my electricity costs go up in incrememts...and it starts at $0.28 per kwhour then it goes to like .32 after a certain amount all the way to .46 or something. So i can estimate i'll have at least triple your energy costs.
I've had $1000 electricty bills for a 3 month period before, and thats without anything growing at all.
