400W HPS and electricity cost???

[Weedywildwoman]

Hey there!

I was worried about lighting costs as well. I have a 400 watt M.H. and a 400 watt HPS and I saw no change in my electricity bill. I did start turning off aquarium lights to even out the costs. If you can maybe turn your fridge down a notch, or something like that I would think that would be enough to avoid any extra charges.

I replaced all the light bulbs in the house with CFLs and started using my laptop instead of my desktop for most things. I think the electric bill actually went down...

The reason I did that was actually to offset the cost of the electricity to my housemates, since we split it equally and I wanted it to be fair. And most of them don't know I'm growing. :smokin:

Here's a couple of older pics of my smaller flowering cabinet. Maybe give you some ideas. Works very well!

my 400 watt hps makes my bill go up by about 9 bucks a month!
