Ill use this for my lighting what do you think?

I am using CFL's for my first grow and was wondering if this amount of light is going to be enough. Im still working out what size grow box I will be using so if you have an suggestions on that bring it on. For 2 plants possibly 3 I will have 8 CFL's 42watt. I was also thinking of mounting 2 of the tube floresents on the sides of the grow box. What do you think? Im in the planning stages and have alot of seeds so when/if I screw up Ill learn what not to do and start over. Also has anyone used that concoction with jack daniels in it that they say you can use in the 4th to 5th week of flowering? If you do how much am I suspose to use when giving it to my plants. When I was reading about it I may have over looked the correct amount.. Here is the link incase you have no clue what I am talking about and want to know about it .

you might have to copy and paste it if it wont let you click on it. Thanks in advance for all the help.

Also how much do you think those lights will run me on my light bill during the 18/6 ? I know cfl's are way cheaper than hps but 8 to 10 lights is what I was going to do.

ideally u want 50w per square foot, u can put as many plants int here as u want

your light bill will go up at most 10-15 dollars a month..since your using a total of 336watts for 18/6

Thanks alot for the information. That puts alot of ease on me since we already use eletric heat our bill get pricy in the winter which is when I am hoping to begin my grow. I am still gathering info and taking notes feels like Im writing a book lol.
