Spider Farmer cheaping out on LED's?

[LowRange]

Hey guys, am in the market for a new LED and was tossing up with the SE5000 and SE7000

However i noticed the SE7000 has less varied spectrum than the SE5000, it shares the same kelvin rating for the warm white, cool white and red. But the SE5000 also has IR and UV LED's also not found on the SE7000. The strange thing too is both lights feature an identical spectrum graph, i don't know how that's even possible when one light has just 3 different LED spectrums and the other 5 LED spectrums.

Anyone know why this is, i thought UV and IR were beneficial. So why would they drop them from their dearest light?

3 spectrums


5 spectrums

those IR LEDs aren't the holy grail everybody is looking for anyways...
They're not the most efficient and the effects are minimal.
Can't speak about UV, but so far I'm happy with my terps without.

I've never run a split test but every website i have read says UV and IR have a noticeable positive impact on cannabis growth, quality and yield. So if you are buying their high end light you miss out, buy the next light down in the same model and you score UV and IR. But the ironic thing i just found, Spider Farmer sell a separate stand alone UV light kit so you can put the UV bars back in to the light... of course at more cost. Nothing about the missing IR.

The first word in both images is misspelled. That's always a red flag with me.

Went to the website before popping off. Lo and behold.

I just bought that upgraded se5000, not for the ir and uv though.

Do Grow lights need FAR RED?

Recent research by Dr Bruce Bugbee and his team demonstrate FAR red is used efficiently by plants for photosynthesis up to wavelengths of 750nm.We also know ...

Reality prolly looks like this:

Are IR chips beneficial to the plants overall, YES.
Would you really notice a difference if they were deep reds or others, NOPE.
So, bottom line: If you're treating your plants like shit, those couple IR chips will not make your bud top-notch all of the sudden.
I think there are other factors playing to big of a role here to get really hyped.

 

[Hollatchaboy]

To me, it looks like there isn't very many ir/uv diodes to make a difference anyways. Am i wrong?

Well, with UV you wouldn't really need that much to stress the plant, I assume.
Considering the IR diodes, you're probably right.

I can only tell that the difference between HPS and Cree-Leds without any 660 or 760nm chips added
vs. full spectrum with 660+760nm diodes was very noticeable.
I just don't see how removing a couple of IR diodes would suddenly kill my game.

Maybe the higher end light no longer has them because of the low quality diode used and it didn't do much?

Adding UVA

You seem upset . I just snagged a Scorpion Diablo for flower during HLG’s Croptober 25% off sale a few days ago and it should arrive today. I will also grab their UVA or UVA XL bar very soon to experiment with as soon as flower starts. Glad to see this conversation up on here for...

UV is actually more a stress factor for the plants not really a big keyplayer in pushing photo synthesis or am I wrong?
Still claiming that the overall yield would be better, even tho it's the least efficient diode of them all is quiet a statement.
Not buying it, prolly the customers aren't either that's why they are disappearing again.

 

[Hollatchaboy]

According to bugbee, there's no evidence uva makes a noticeable difference, in tests, anyways. I don't believe uva helps in photosynthesis.

I remember that thread. Lol

High quality stuff.

i dont want uv in my grow area i am under these lights too and uv is damaging to eyes and skin and also it turns plastic and fabric into dust over time. which i guess this dust will be lifted off by your fans speck by speck and will be trapped in your buds and shit.

smoking my microplastics no thanks i prefer to eat my fish haha

ps: but showing the same spectrum for both in the spec sheet is really strange

I don't think they have enough UV to do anything. Those Chinese companies (and others) would put pepperoni on their lights if people bought it.

If they do mozzarella too, I'm in. Pizza spectrum for the win.

I’ve ran a control plant 2x, mild difference in color, same THC content, no noticeable change in taste, yields equivalent. both with Mars hydro LED with an w/o IR.

As others stated, it’s probably a 1% change where as purchasing a PPM and PH meter and balanced nutrients + good water and/or soil will jump you way more for the $.

Attached: Week 2 flowering Hindu Kush. No training. Liquis nutrients + water. Organic pro soil. T5 light until 6 weeks then MarsHydro 600W full spectrum. Highly recommend their light fixtures as well if you’re looking at other brands.
