Since HPS and MH fixtures generate so much heat, is it safe to say that because you can place fluorescents and CFLs more than twice as close to your plants, that you are essentially needing half the lumens when comparing to an HID? If in reality all one would be getting with an HID is say, half, does that mean that a fluoro setup, given the right amount of lumens say 13,000 can be equal to a 250 watt HID if placed twice as close? Especially since fluorescents have a more favorable color temperature for plant growth? I know that there is a certain math behind all of this but I really don't know this math! Please help shed some light!
