Paisa, dude....I see people talking about cfl's and I see you talking about having high expectations. I feel the two contradict each other.
While I am sure you can grow a beautiful plant utilizing nothing more than cfl's, you'll certainly take a large hit in the yeild department.
Marijuana is a high light requirement plant, although it will adapt to a low light solution such as CFL's. It will however grow slower, and yeild less.
I am not looking to argue, but you did say that you have "high expectations" so I am just trying to help you make the correct decision from the onset.
Heres a simple point for ya....
A typical CFL puts out 60 lumens/watt. Because it’s about 10% more effective at producing PAR light than an HPS, we turn that into 66 lumens/watt when comparing to the 400 watt HPS.
A 400 watt HPS puts out 125 lumens/watt.
So, a CFL puts out 47% less PAR light per watt than the 400 watt HPS. By making the switch to CFL, you’ve become 47% less efficient at producing bud, and 47% less green to the planet.
If light were the only determining factor, you’ll yield about 3 times less bud per crop using 262 watts of CFL than you would using 400 watts of HPS.
A watt of fluorescent lighting creates about the same amount of heat as a watt of HPS lighting. If you used a 150 watt HPS, you could put the light within a few inches of the plants, you’d create 43% less heat, spend 43% less money on the electric bill, and deliver the same amount of light as the 262 watts of fluorescent. It’s the green smart way to light up your space.
Peace
