My 600 watt hps is too big to allow another hanging light to fit, but I could add some lights mounted on the wall if it is worth the money and will be beneficial. I want to have more light but don't know what kind of light to get. Any suggestions?
you can see in my thread, that i had it nice and reflective, then added t5's as i felt necessary, just to give you an idea of what you might be able to do
Absolutely beneficial. When I grew with CFL's, I grew in an area 2ft x 4ft x 4ft. I had 12, 23 watt bulbs hanging from the top, and had 4, 4 ft. florescent lights on the back wall. They made a big difference from my first grow with out the back lights. This is how I have my tent set up currently, but when I get the chance would like to add some more lights.
