Phat Jays current grow. 4 x White Rhino staggered under 250w HPS. (PICS)

Do you think the 250w of HPS is better than the 500w of CFL ?

Yes, very much so. I get around the same yield for half the electricity cost. Also, under CFL the trichs took forever to amber and the plants would take at least 9 weeks. Under HPS they are done in 8.

Would you not think of adding the 500w of CFL with the HPS for the final few weeks of bloom ? I think you would get a fine boost on bud !

I am at my temperature limit, I cannot add any more light without a major system change. If I did add more, it would not be CFL. I used CFL's for flower for 2 years, I got great results, but HPS definitely has the edge in most scenarios imo.
