I am no less than 12"10 inches minimum for spectrum blend. Usually about a foot away

I am anywhere from 2-6". I make sure to reposition everything regularly for spectrum exposure.I am no less than 12"
Ah, I didn't realize that the fiji and coral wave had that much UV-B in them. How did we arrive at the 5% number as being the max amount of UV-B? Is there an article or thread that analyses UV content and its effects?the fiji purple and coral wave have 5% UV-A and UV-B. anymore than that and you couldn't keep the lights on for a full 12 hour cycle. It would damage the plants. The fiji purp has 5% infrared and the coral wave has 35% infrared.
so no supplementation is needed
There is a video on you tube some where and an article in high times from around 6 months ago. Both are Ed Rosenthal and Nasa doing LED and UV-B experiments for space at University of Maryland. The UV-B lights they were using are 10% UV-B. They tried using at various schedules. At a full 12 hours, there was damage to trichomes an leaf growth. It didn't get more specific than that. They came to the conclusion that having it on for 5 hours a day produced the best results. To have it on for full 12 hour schedule it would have to be less or possibly half the amount of UV-B that they were using.Ah, I didn't realize that the fiji and coral wave had that much UV-B in them.

Does the far infrared just aid with flower basically? I know the professor was looking for some far infrared bulb to simulate the dawn and dusk wavelengths in the late summer/fall.
Very cool! I must check that out!There is a video on you tube some where and an article in high times from around 6 months ago.

The video is just ed rosenthal at a convention talking about the experiments
eh, someone posted a ways back saying that the Fiji Purp used to be manufactured by someone else and that it was an accurate spectrum graph according to the prior mfr. The current mfr does not divulge that info. So it's really up in the air. Don't use it if you don't wanna, heh. I feel it is a good bulb. It is working well for me. That's all i care bout honestly.WOW. I had no idea my Coral Waves had that much infrared. I have 2 of 8. I haven't noticed any eye strain.
Since we never got a spectrum graph on the Fiji Purple, I don't understand why it continues to be promoted
These bulbs are praised by even the best aquarium enthusiasts for a myriad of reasons. AND i have yet to find a SIMILAR bulb that gives the same spectra. Yes we dont have a proper spectrum chart.. ill take the one i can find though....WOW. I had no idea my Coral Waves had that much infrared. I have 2 of 8. I haven't noticed any eye strain.

haha yeah it is javascript because it's not there for me, nor can I use the big like button. Oh well. From now on, just assume that I like everyone's posts!Red, the "Like" is just a single word that shows up in the bottom right corner of the post, right above the poster's signature and straight north from the "Multi-Quote This Message" icon... it just says the word "Like" and it only appears while mousing over each post individually. I suspect this is some kind of javascript. But as Reefer said, I believe you can also like it through that drop-down at the top. I haven't messed with that tho.
AND how are you trying to find a SIMILAR bulb that gives the same spectra, when you do not even know what that spectra is? Did you obtain instrumentation to measure the spectrum of the fiji purple? You'll take the one you can find though... The spectrum from another company's bulb (nlite PURple), that isn't even on the marketAND i have yet to find a SIMILAR bulb that gives the same spectra. Yes we dont have a proper spectrum chart.. ill take the one i can find though....
Are you anti javascript for a particular reason?haha yeah it is javascript because it's not there for me, nor can I use the big like button. Oh well. From now on, just assume that I like everyone's posts!
