UVb an experiment

this revel bulb is emitting at both 660 and 730 so i should not use it right?i am leaning toward using HPS only on one side of my room and clear inc's and HPS on the other.800 watts of inc's only for 30 min than 800 watts HPS only for 11 hours than another 30 min of incs only on clones from four verities SOG style to test for differences in resin/tric production and maturity . what do ya'll think?

sounds good to me.. post pics and all that :thumbsup:

Yes that bulb looks good.. If you keep testing, I think you will see that you can run those inc's up to 6 hours and your HPS 6 hours and get good results.. Starting out with one hour of inc's is how I started...LOL... Now I'm up to 6 hours of inc's mixed with a small amount of low wattage 27k cfl's...It just keeps getting better...

It's what called "Rauber's Substitution Method" ..... Chapter 10 of the PAD manual... Good luck with your grow..:thumbsup:

After researching that bulb you posted.. It turns out that's the same bulb I use.....LOL....Thank's for the spectrum chart.. That's awesome.. No wonder the bulbs works so good.. The link I posted above was from Home depot. I couldn't find a chart for it... :thumbsup:

what about blue cfl's?

Nice thread!

Weez, I scanning as fast as I can right now, but I think you posted a comment about how hard BLB (Blacklight) Inc.'s filaments are run to produce more UV.

My research (not that I'm right, but) indicates that the filaments are identical and the only real difference the bulbs is the BLB glass (Wood's Glass) used in the outter envelope.

In other words the Far Red output of the BLB Inc.'s is basically the same as the Clear Inc.'s, the main difference in visible emission.

I dissagree with UV results as false Far Red positive possitives as the light sources used usually indicate. Far Red doesn't give hit and missed or "mostly" results.

I use what I personally have experience with. Considerring the cost of Clear Incandescents verses the cost and added complexity and DANGERs of ballasted UV lamps, I would suggest serious Qualitative growers get "EXPERIENCED" (Jimi Hendrix).

Gotta Run (crazy work load today).

Take Care, Sal.

Howzit, Sal?
Good to see ya back.

I'm fairly sure about the thinner filament being used to push the color temp before filtering, though I have no actual facts to offer here.

It think it's what causes the relatively short life expectancy.
That, and the heat generated in the Wood's glass from filtering out the visible light,

'strue that 60Watts is 60 Watts, but running the filament hotter shifts the emitted wavelength towards UVa and, unfortunately, will shorten the life of the unit.

Clear incandescent lamps are indeed much cheaper, and longer lasting, but I was not sure of how to factor in all the visible light frequencies that come with.


Now, ya gotta help me out wit dis one.

"I dissagree with UV results as false Far Red positive possitives as the light sources used usually indicate.":wtf:

That went in my eye and is still spinning round in my skull.
Cognitive dissonance of the first water.
Darn near as bad as.

And then there's;

"cost and added complexity and DANGERs of ballasted UV lamps"

I think ya lost me when ya switched subjects.
Party bulbs have no ballast, and I'm using the Sun as my UVb source.
Mebee slow down a tad so's us mere humans can try to follow it too.:rastasmoke:






Take yer time, brah, not critical.
I'm just tryin' to follow this for the science.
Last thing I need now is more, or stronger buds.:stoned:
Tough life, yah?

Easily confused, Weeze

Sal don't run...LOL.. How you been. Was thinking about shooting you an email. Now your here I guess I don't have to.. I 'm looking to start a tread on 420 mag in the LED section.. I was wondering if maybeeee I could get some oversight with my tread over there when I start it...LOL.. I know your busy... But I'm a rookie...:rasta:

[Dogznova]

Weez.... I think he was referring to the Far Red comet you made a few post ago..The one that say's you didn't get much effect from Far Red .. Don't quote me though..:thumbsup:

The other part of his comet seems he is talking more directly about UV-B bulbs and the danger associated with them...I think this is what confused you (ballasted UV lamps).. I had to re-read it myself...

Not till the end of next month, I'm in Civil court till then, but if you post a thread there I'll have to join the site and for some reason never got past that point with ICmag, but maybe 420 mag wont be repeat of that.
