grolux bulb vs. daylight bulb

[baruch mor]

considering ill take the same size of bulb, lets say t5, 54w 115cm long. do u believe beside giving better color (i like the grolux color on my red plants) the plants will grow faster/healthier under gro-lux bulb comparing to regular daylight bulb (osram/silvanya 865 - 6500K , cri >80)?

Re: grolux bulb vs. daylight bulb

Have you read Toms new article on lighting? From what I can gather total watts of light are more important than actual spectrum. I'd go for what's more visually pleasing, if you like the look of the gro-lux then use those.

I like the 9325K GE fresh/saltwater bulbs,the plants seem to pearl more with these than any other bulb I've tried and the colors are vibrant under this bulb. I don't know if they are made in a T5 configuration though.
