Cree 1000W DE HPS Replacement Reference Design

But is it the true horticulture reference...
"true horticulture reference" ? It's the same black-and-white argument I received when suggesting the 3500k is not the best choice as well as earlier in this thread. Not knowing the ideal spectrum doesn't have to stop one from making informed decisions based and provide a reasonable reference.

They obviously created something rough, based on the gavita/hps, with the note they added a little more blue (already) and that the recipe can be finetuned as desired. They obviously do not suggest it is already a finetuned spectrum for a specific or all species. Suggesting they should have tested the spectrum and various recipes on many or any crops is unreasonable. I hope that entire post is a result of you being crazy high and that you will find yourself on a more constructive path tomorrow. All those questions in your post are just to cloud yourself from seeing the obvious.

I, just like you, want results. I already know the electrical side of it. I also have flowered with pure white(3000, 3500, 4000, 6100, 5700), white red combos from 1:3 to 3:1 with a few different bases, and plain red:blue. I know where they all stand in both even and uneven playing fields of photons. I could care less about COBs, and have said many times how I dislike them. I do however love high efficiency phosphor conversion white leds. And reds too. And whatever combo can get the most quanta at the lowest cost.
I love that they have embraced W:R...and have already said that. But I want to know why, how, where, and who.
Look into spectrums kings tempo testing. At 840ma cree is dogging that drive current as moderate possibility of electrical overstress before cooling is even factored in. Then they drive the same chips at 1050. Convenience and cost no doubt. But not their best effort at a quanta machine. And if to them there is more to it than raw quanta...where and how did they come to that?

Thank you for looking into this. Maybe if you said the exact cost per board, we could get a group buy together?
Earliest I'd be looking to place an order would be late August/early September. I'd happily be part of a group buy or order extra boards for you (or anyone else) if I go ahead.

I need to have my current grow finished and my next grow up and running before I touch lighting. I've promised myself I can make plans but not place any orders until then :oops:

Wow, I thought this would be a good thread to read, because everyone I talk to that is a legit large scale grower is using the 1000W DE. Can we get back on topic here?

It is a pretty simple equation of spectrum and cost. I do think buying most any off the shelf LED is going to be to expensive to replace the 1000W DE for large scale grows, maybe for small grows where there are different limitations. I also think the idea of people designing LED grow lights with more then 2-3 year life spans is waste of money because the technology is progressing to quickly. Better to design a less expensive light with a shorter intended life span, or ability to replace out the COBs as they improve year over year.

Cost wise, building replacements for 1000W DE could be cost effective if done in house for a large grow. There are also ways that you could build custom LED systems for large warehouse grows that integrate into existing HVAC systems, in theory greatly reducing costs by eliminating system redundancy.

Also, lets not forget liebig's law. I would be willing to bit that in 75% of grows light is not the actual limiting factor, human error and lack of skill are.
If people would just try straying from popular efficiency belief, more actually grew pot rather then argue over growing pot, then they would easily have made a 1000w DE replacement w/ the COBs they have now.
Crank up your COB.
Why not?
1) you'll yield allot more then you save on your punk ass electric bill
2) COBs will actually have penetration, even if you spread them a mile apart. (W/lens)
3) Who gives a shit If the efficacy is dropped to 1-3 years, your replacing it in 6 months anyways due to technology up-grade. Wouldn't you rather get the most out of your cob now, before its rendered (old, out of style)
I agree about why make these lights to last 5-10 years. Instead, why not make these lights actual 600-1000watt HPS replacements that can actually grow mad pot.
Orrrrrr, you can keep being sooooo efficient, in the mean time bitching & moaning about how your new LED light you bought or built can't grow like your friends HPS.
So many here never even used HPS, DE or any of the big hitters but all want to replace them. I don't get it. I know what these lamps can do, that is why I have much higher standards for my LED then so many i see that just want a 600-800 PPFD on the top of their canopy but absolutely nothing 6"-1' below said canopy.
Then they post of bunch of pictures of bud tops only saying: whatchu mean Willis?, look at my bud tops! LMFAO! Get real.

Math is great until it costs you $10,000 less on your harvest cuz you thought efficiency on your bill is all that mattered. Ha! It's all good, after all, you did save $20 on your bill trying to replace 1000DE with 1/2 powered cobs spread 1' apart.
It's all good though. You do you n I'll do me.

I think your 75% estimate is a bit on the low end. I will take your bet and raise you with 24.99%.

Apart from a few exceptions most growers here are not grower enough to discuss grow light. Buying the most efficient cobs on paper and tying them together is the main event here. For actual discussions about grow lights, what this thread could have been, this just isn't the place.

Although, when you put @captainmorgan, @PurpleBuz, @churchhaze, @testiclees (he's lying about the "es"), and @PSUAGRO. on ignore this thread cleans up nicely :twisted:
I agree. All these threads would be allot better & useful if the guys that did NOT even grow pot were not part of them. Still trying to figure out why they are here at all??????? Just to argue about things they've never experienced......

I would love to run some cobs super hard a citizen clu550 running at 500w would be dope only problem is getting a heatsink for that much power

Having read what you've wrote a number of times, I get the impression I know your type. I'm from Nor Cal, home of the idiot commercial grower (sub 100 IQ without an original thought in their heads). I've met many of you. If you think these things, then go do them. Otherwise, let the smart people muddle over what you will eventually buy from a hydro shop when we've figure out the right things to do. Think street lamps were great for growing immediately? No, smart people worked on the bulbs and ballasts to make them more efficient.

Actually, hey guys, he's got it all figured out. Lets go home. Just drive your COBs hard for penetration, done.

You're right. This is not my cup of tea!
I am not a smart guy. Just a grower. This is not the Kindve stuff I ever thought about in the depth you guys do. Just an opinion based on the things I've read here.
Peace to all, I'll stick to my journal.
