CFL Gels

  1. I just read Kamel's CFL guide.

    Has anyone tried using photographic CTO color-correcting gels with daylight balanced CFLs to emulate an HPS's more orange color?

    I'd really like to know if anyone's tried this. If so, how'd the grow fair?
  2. Thanks for checking out my guide, and I'll admit I don't even know what you're talking about, but it is most impractical to try and filter the spectrum of a CFL, especially trying to get the red out of a daylight. Look at the spectrum charts I have in the guide a couple posts down. Daylights don't put out a whole lot of red, so what you'd be ending up with is a very weak bulb that would be essentially just wasting energy. CFL's are cheap, just get the soft white, they are the same color temp as most HPS bulbs at 2700k. Some HPS go as low as 2100, but 2700k is pretty red. And common, if a store carries any CFL's they carry soft white.
  3. lol wtf you can buy 2700k bulbs more often than daylight where i live, why on earth would you need to use a gel
