Yeah, that's really ambitious. Best of luck. you're working with 120 square feet. It's reccomended that you have 5000 lumens/sq foot optimally but its a good rule to go by, with your square footage that's enough for over 6 1000 W HPS systems. That's just going by the math from others on this site. According to the light manufacturers they say a single system will cover a 10x10 foot area. My guess is that if you only put one of those systems in your area some plants would be severely lacking but its all up to you. Each one will cost several hundred dollars, you better have about a grand in capitol to get this thing off the ground.

But shit with the amount of output from that little area...you could be making a quarter mill a year easy. Fuck the government has made marijuana lucrative.
