LED vs. HPS

[PitViper]

The 190W LED is to replace the 800 hps that is the claim i want to see it.At 1 gram per claimed watt.This is the number posted by the company not mine.light vers light LED will come up short everytime.spend the 750 bucks on the 800 tell me how you do.we did the research on the LED before any purchase was made.was not in our best interest to buy them.They inflate there number with no real data.Its all BS marketing.

I don't think they ever claimed 1 gram per watt, but they do compare it to a 800W HPS. For the typical grower that's like between 0.5 and 1.0 lbs I think. Anyone else have an opinion for a basic rule of thumb? Yes, you are doing better then that, but you are not typical. Hopefully, Budalicious is still around and is still going to post some results. I just don't have the space.

It cool man np thanks

I'd be happy to see a 1 Gram per Actual Watt LED(-only) grow.

I'd be most happy to see side-by-side comparisons done by someone capable enough to pull off consistent grows when the genetics are identical, who would use two separate but identical areas (so as to not cause "heat contamination"), identical clones, growing methods, etc.

And since many people grow with a 600-watt HPS, a 400-(/430-)watt HPS, or some amount of them... I'd like to see the LED side set up with 400 or 600 watts (or within +/- 7.5%).

^^^^ Here Here!!! I second that opinion. Solid, respectable data is what's called for.

Cheers

Hey, sorry for the disappearing act. Sadly, I've been having some issues with my babies which has seriously delayed the timeline for my grow. It's my first attempt at hydro - thinkin I may have tackled too much at once cuz I'm struggling with keeping the environmentals and res in check. I had been meaning to start posting pics of my grow by now, but I wanted to wait till I had more to show for it! Things are improving so I am hoping by next week I'll be able to start my grow journal.

Funny how marketing always travels ahead of the data needed to truly back it up... there should be a law lol.

Yet folks continue to believe... once you can get someone to buy something, they become part of the cheerleaders instead of the skeptics.

Maybe it's a defense-response in that they do not wish to feel that they wasted their money?

Or, in layman's terms, nobody wants to be a sucker.

HPS is NOT an option for me, the power bills are to high and my cabinet would melt. The Haight lights work, you can keep paying hundreds per month in power bills if you want, but LEDs are a good option for many.

I just read in the paper about another fire caused by a HPS grow in the sunset district, and there were a couple in LA. If you like wasting money on your power, keep at it, but when the whole thing burns down how much will that cost?

Well it's been a few months since I got on here. I've been upgrading my LED system, and have almost completed a run under the upgrade. I'm still about 16 days from finishing this run. So here is what I've changed. I still have three pannels of LED's, each pannel has 6 blues, 6 cool whites, 8 deep reds, and 20 reds, all in 5 watt LED's. I may be off on the reds by a couple, but close enough. The power used by all three pannels is 390WATTs, but the system ended up using 420WATTs, go figure. I used to run a 400/600 combo system, so I know what I'm looking for as far as results. Now I have not yet dried my crop, but I can already tell I have at the very least gotten about the same results as under the haloid/HPS combo, but I don't see as good a reson globs as I think I should. I did notice some other good things though. First, the water usage went down, and I didn't have to use as much fertalizer. That's a good thing. I did have to extend the harvest out one extra week, so what.
Now back to the reson issue, I want to add UV to my mix, but what frequency do I need? I'm thinking 405nm. Does anybody know any differant?

If HPS is not an option for you... then you are not a sucker.

I certainly didn't mean to infer all LED growers as suckers... as many, such as you, have legitimate reasons... however, if you buy the line about fire prevention being a reason to use LED over HPS... well... I gotta bridge to sell... cheap.

Poor wiring is what causes fires.

Power could be an argument... but $30 a month on my 600 ain't gonna break me, nor many others I would hope, especially when you consider the end result of at least 8-12oz from $90 of power. It remains to be seen if LED can actually match this level of production, even at the same wattage.

Much respect to those who are trying to show a proper LED setup can match or exceed HPS production... but the "claim to proof" ratio is still on the HPS side.

Cool, that sounds about right. Glad to hear from another believer.

Sorry, I don't know about UV. I don't think HPS generates UV so that may not be the problem but really I don't know about that.

The lower water usage makes me think perhaps your room temp is lower because of the lower power. It might help to add a small space heater.

We all get a bit married to what we have, it's no different for the guys defending HPS.

Poor wiring causes fires if you try to power a 1KW lamp, but it's a lot less likely with a 300W LED

Power here costs up to 44 cents per KWH, your 600W would be about $150 per month running 18 hours per day.

It's just a matter of time before more people tweek things in with LEDs, people have had years of experience with HPS.

I have to disagree with the first statement, as HPS has the benefit of proven, repeated results.

Yes, they should require licenses for a 1kw ... but a 5.1 amp digital ballast 600 isn't going to stress most 15 amp circuts.

Not going to check the calcs... but no argument that LED has the potiential with regard to power consumtion.

Agreeded as well that is it a matter of time before LED overtakes and replaces HPS. I guess our disagreement amounts to: How much time?

I think the LED technology itself needs improvement... could be six months, could be a decade... but just not seeing results to change my mind... which I do strive to keep open.
