I'm not interrested in saving you time. But I am interrested in making you get your head in the game, and answer a simple question that you keep deflecting. Like is there a difference between Dual spectrum (commonly Dual Arc) and Full spectrum?

Since you seem to avoid research or taking your whiney ass over to a bulb retail site to see if you can distinguish between the two bulbs, I'll do some of the grunt work for ya... (or were you unable to find the answer...?)

The one I'm currently using is here:
My full spectrum bulbs.com
Inside the glass envelope is one long ceramic (or titanium for all I know) filament and support wires.
I might re-purchase, I might go with the standard rather than full next time. Depends on what's on sale. Each has it's own strength and detractors. Dual arc (dual spectrum) bulbs I avoid.

Here's an example of a Dual spectrum (dual arc) bulb:
Unnecessary and overpriced growbulb.com (sorry Dutch...it was just on the next page and easily accessed )
Inside the glass envelope is one semi-long ceramic (perhaps) filament and one MH pillow, or packet, (or whatever the heck it is) and all the support wires for both. Tiz a MH/HPS combo in one bulb.

As far as my experience takes me (around the block once or twice) the inner workings of the Full spectrum bulbs do not have the MH pillow addition, like you see in the Dual arc.
You are asking me to compare apples and oranges, and I tire of that game easily.

If this is not what you are refering to, then spell it out. I really am trying to understand what you're getting at. I'm losing my patience in the process, but that's not unusual these days.

As far as the spectrum chart goes...were my goals to have my hobby all-encompasing of time, effort and cash, and were I so anal about the minutia that I'd overlook the benefits of keeping it simple, and were I to not trust that tens of thousands (an estimate to infer actual knowledge) of indoor gardeners have had and continue to have success with a system or a piece of equipment, or a product's effectiveness, I'd keep along the same path as yours. Dewlling on something that is truly inconsequential.
We're talking about 110,000-140,000 lumens or so, (which BTW...my plants love) not a concentrated million watt laser.

If you fail to learn the benefits of doing what works for very experienced gardeners all over the world, you're doomed. And if that is the case, why do you need our validation...?

Me...? I use what works and I use it well. :jointsmile:

A couple of pictures to illustrate the two bulbs...

"Our results show that photodamage to PSII by
sunlight is primarily associated with UV and yellow
wavelengths (Fig. 5), "quote from PDF many growers feel that UV light changes/modifies the guilty/quanity of their medicine for the better. i myself flower under HPS until the last few weeks. i then finish with a MH. been doing it like this for a loooong time because it improves the smell , taste ,high. i have always thought that the blue from the MH caused these changes but have recently read that MH puts out a lot of UV rays so maybe its the UV? I also use the cheap bulbs and am quite pleased with the results. but i guess im rambling .will filtering out that yellow peak make my plants grow noticeably faster? will adding more of this yellow have an affect for the positive?when will my lunch be ready???

do the LED growers grow awesome buds with N0 UV OR YELLOW ?

So I hear.

Awesome, in this case, would be a completely relative term. I would like to think so, but my personal experience included, I feel my HPS buds are more worth my time. LED is great technology but it's only true application ATM is in micro grows. My opinion only.

So a dual arc bulb is not the same thing as a "full spectrum" HPS. Who cares? You use an HPS so have become defensive stating that "full spectrum" bulbs are somehow different. I tell you now: They are not different enough from a generic HPS to matter and anything that is actually different is not actually HPS.

Anyhow, I guess it was a mistake to think that any of you cared to improve your undertanding.

Well...if you want to put it like that, I'll put it like this:
For starters, usually it's a good idea to know the subject matter and have practical experience before telling someone with both they are wrong. You can worry all you want about the similarities in light spectrum with different bulbs, or you can accept that it (HPS) works just fine. All three types of bulbs (dual arc, full spectrum and 'regular') each have their plusses and minuses.

Were we not concerned with growing the best meds possible, we wouldn't be here dispelling rhumor, inuendo and bullshit. Were there any possibility of consequential damage, do you think anyone on any cannabis board would recommend it's use? Get a grip, and pull your head out. It is SERIOUSLY nothing to worry about, and your consistent slamming of the equipment has become laughable. What next...a warning that sunlight might be damaging to our cannabis plants...?

You keep repeating the chant about damaging light and spectrums, but you offer no alternative, and obviously are not absorbing the material offered. I've asked you this question before, but I'll try one last time.
What is your alternative?

"Our results show that photodamage to PSII by

wavelengths (Fig. 5), "quote from PDF..................ok so the article does say that but sometimes what is seemingly bad to cannabis is good for the grower.
we cut back / remove nitrogen during flowering = leaf dies,stress a bud to get hermies=femmed seed, provide extra UV =resin changes.........these methods have evolved over the past 40 years because we exchange info and try new things. i will soon be adding far red light to my grow to see if it has an affect not because i feel my smoke "isn't good enough" but only because i'm curious by nature. now i'm curious about this yellow light damage....what is its affect on pot? good/bad? pure LED growers could tell us rather quickly....any volunteers ?

forgot to point out what most of us already know....potency is mostly genetics .you will only get small /subtle changes by manipulating your light spectrum .correct me if you feel different but lets try to stay on subject.
