Going from HPS to LED. Worth it?

Kingrow1 said:
I am paying attention and can quote where multiple led growers of various skill levels say leds smash and out yeild hps. Now either its one or the other, if i wanted par i dont have a problem mixing plasma and hps! Oh and by the way i mix every spectrum of t5 in veg but it still isnt much better than just blue on its own, par shmar!

Look at the trichs on the babies. @RM3 gets lots of frost on them with UV in the seedling zone. Does it make a difference? Perhaps in terms of the plant being better able to handle high levels of UV later in its life cycle, which would seem to be a good thing to me.

I've run HPS in conjunction with other lighting and IME the plants hated the HPS every time; they didn't do as well, they would show a strong phototropic response towards other lights even if they were further away, and they were more susceptible to higher nutrient strength.

That's why I don't recommend mixing HPS with other lighting, because I never got results that I could call better than just running the other lighting by itself.
 
there is no way a same watt led will pull 50 % more then a hps . I some times throw 2000 watts on top of a few plants instead of my usualy 1000 why not and I average about 30% more hortilux with solis tek digital ballasts . so how the fuck will a led pull 50 % more that's bull shit . so I am comparing 2000 watts in a 4/4 area . to get only 30 % more ,

It was just a simple question that most would like the answer to i.e. do leds yeild mpre than hps? No need for the 5 page science lecture on par or anything else and a lot ofus just grow for yeild not to make pretty buds that have the best quality.

Going with the flow seems easier than trying to get an actual answer so there you have it 'Leds yeild 50% more than hps' no argument just fact that ive regurgitated from these forum boards... :-)

I do wish that I had such a simple answer for you.

However just as it's possible to use HPS in a wide variety of ways with varying results, LED is if anything even more flexible.

Therefore it's possible for a good, we'll dialed in HPS setup to beat a half assed LED setup. When skill and differences in approach are factored out, I'd say LED beats HPS cold. Especially for quality of results.

Different light spectrum and more light sources thus better penetration. There are people who have proved this by comparison. If an LED is 60% efficient and a hps is 30% then for the same wattage your getting more photons that are more useful and closer in spectrum to what the plant has evolved in nature over millions of years.
That's just a couple of thought on the how.

Well now, that's not comparing apples to apples, is it?

If you want 50% more yield, then use 50% more space along with 50% more light. No free lunch.

If you are space or plant count limited and you need higher specific yield numbers, then it's time to compare watts used to gain the needed level of intensity.

Subtle, but different. LED is better because of spectrum, efficiency and/or light distribution to the canopy. Not necessarily all three every time.

I know dude, no arguments here, leds are absolutley killing hps for yeilds, op should be looking at 16oz minimun after he gets rid of that redundant 600w hps and upgrades to a 450w led cob.

Leds totally rock over second rate sodiums...

How new is new? Led has been around for decades.

Higher up front coast doesn't seem to be stopping sales at the Cadillac dealership. Maybe you're getting something worth paying for?

Who said all led was less reliable than light bulbs? Why do you believe them?

Just saying;

about a pound and a half dry ??? here 1000 watt DE 6 pounds 2 week veg 2.75 GPW

As for LED Nope gallery_12772_5190_123099.jpg

Swap that crap out for a 600watt led, promise youll smash those low hps yeilds easy, more par and less electricity :-)

You think ??? still waiting for COB or LED to come even close i will be starting up in end of Dec a thread going to bump up plant count and go for it another grow 1 k 8 - 10 pound harvest :) with 3 weeks veg longer veg sealed room i think i can beat 3.25 GPW
