Led vs HPS growing

Idk guys, having a hard time deciding.
Its two light brand names that have been in the lighting industry for yrs so they must be good right?
Either the Fiet Lighting Special, fully customizable Hybrid 70
Or the GE Arize?
Tough decision.20200824_051650.jpg20200824_051737.jpgScreenshot_20200824-121226_Hancom Office Editor.jpg20200729_223347.jpg20200729_223427.jpg

just using your own arguments. but let’s specify this. whats the difference in white led deficiency purple stems and natural red led purple stems?
All i can say is the red stems caused by the red light do not slow plant growth like the purple stems i see from white LEDs once it gets to far gone.
There's a big difference.

With this being an LED/HPS thread, are there any HPS users out there who want to argue over which bulb is best? Or how my reflectors aren't correct size for my space. Or how I'm screwing my bulb in incorrectly?

Or are you all to busy "growing your weed" to come throw down?????
Kinda feeling left out of the conversation...:oops:
HPS is a time proven grow light. very little to discuss. the same is true for H.I.Ds T5s and CFLS. other than improvements in bulbs what is there to debate

I'd like to know if I compare output of different lamps if the comparison is actually even & fair, and since we know PAR is not all I wonder how much of HPS strong IR peak is counted in? Should it count or maybe only half? Temps under LED seems sometimes to be too cold and almost optimal when HID & LED are combined in greater rooms...
The whole way LED presents their case is from an efficiency in sacrifice of spectrum, some of which appear rather like a castration or nuissance to strong lightlevels.
Then one needs to go to extreme length to amend this spectrum to get it more complete in reference to the suns spectrum when it hits here the ground. But even at that it takes either horrendeous hardware cost (UVB) or non-efficient electrical conversion rates in certain wavelengths like cyan, green or IR that it renders this approach still somewhat con-competetive.

I mean, just think the other way, the UV led may corrupt themselves, and these wavelengths cannot be generated so cheaply than 660nm so in a high-K MH bulb you got quite some raw output in that regions - but it's not PAR lol. But it's actually more precious than PAR, esp. UVB as it's superpotent as a radiation in response of the UVB-8-receptor and it serves as a multiplicator of the quality, when it raises cannabinoid content. But some say "it's not needed" lol... but never offer laboratory proof!

The strong HPS endglow when shut off gleames minutes-long in FR & IR and instantly initiates the darkbreath and the transformation of NADPH+ into sugar and starch. Here LED must further invest, only very few companies have control-able channels and some of the websites out there looking for potential customers for their outstanding expensive racks seem run by scammers. And even more dishonest. They screw around with their numbers, as amateur you'll never notice the cheat! high umol flow but @ 30° lense! But we don't wanna shoot lasers instead promote spread, uniformity in strength and deep penetration instead of burst!
The UVB diode seems to be in dilemma - expensive, very little needed, but highly-inflammatory radiation calls for an equal spread - not emittance from a single diode which is rather strong nearby but ineffective outside a small proximity. But the high price forbids the addition of multiples of these driven in undercurrent.

Those are some of the most heart breaking grow room pictures I have ever seen. You desperately need a real life friend to bitch slap you for that. Just wow man.

Edit: I just got through the thread to see what happened to those naked ladies. Very nice work and results. You seem to have your room and lighting dialed in nicely. I could never strip my ladies that naked though :) Forgive me if I missed it, but what was your total yield on that run?

Superior hps spectrum? IR at night promoting sugar production?

great arguments LEDS are good for supplimental lighting but need more work before they can replace HPS or CMH
