8 CFL's... LOL serious.. 8 - 150 watt cfl's...

3 plants.. although the pictures are of just one plant
There was enough room for 1 more plant to get the same amount of lighting
Yes.. all the tips are burnt.. Lights touched leaves all the time...
The rational was this.. a little bit of incidental burning was less harm than keeping the light more than 1 inch away

FYI- I did not grow these plants.. SeeMore did..
