Help choosing an LED replacement for 1000HPS?

[Rahz]

lol... wat... that's such a rip off!! I've never even seen the cobs they're using too. I doubt they have efficiency that can compete with top bin cxb, and yet look at that price!!

I checked the chip manufacturer's website and looked at the datasheet for the 500w array... 90 LPW.

Edit: Now, just thinking off the top of my head, a 500w emitter nominal current being 15 amps... under driven at 1.4 or 2.1 amps, might be fairly efficient. Depending on the price it might be worth playing with.

There is this overpriced device http://growlightsource.com/hp4s-300-advanced-energy-saving-led-grow-light-made-in-the-usa/led-grow-lights/ ....... or you could build your own

Whoa! That's crazy expensive! Who would ever pay that for an LED? And it's not like it's the biggest panel either!

I was waiting for that one lol ^^^ seriously you do not think environment, nutrients play a crucial role what about VPD ???
what puts out more UVB MH or LED ??? which produces better resin a plant grown 15,000 feet above sea level or a plant at sea level ??? what about strain could different strains create different resin profiles ?? here DE grow resin looks pretty dam View attachment 3435385 good to me does it to you ???

have u grown with any new LEDs?

 

[JimmyIndica]

WTF ???? only reason i came in here is really to get to the bottom of a lot of shit being spewed and false info leading new growers into false pretense of thinking there going to out yield or its better the hps lighting systems
and the problem is ,,, THE BS plain and simple the arrogance the tight religious group of nitwits plain out spewing BS takes alot of buds to make 19 oz ok or so called 76 oz wet
lets put this into perspective here are some pics of that grow please note ,, in that thread he is talking about chopping ,, also note the picture of him holding or hand around the bud ?? ok
now that bud dried is going to be small and lose lots of weight if you think in all honesty that is 76 oz or 19 oz plant ??? think again its shit like that in reality that makes LED or COB a bad name View attachment 3435422View attachment 3435424 View attachment 3435425 View attachment 3435427

Is that u with your small /airy no resin buds? BUD!

Whoaaaaaa aren't we all friends here? I think a few guys need to pass along the pipe! Lol..

But guys let's please can we try to stay on topic and in a good way? Please? K thanks.

I've been looking more into these websites a bit and it seems like they still selling old tech and not really keeping up with the adcancements in LED technology. Area 51 looks decent and so does the Hans panel, but these other commercial guys aren't looking so good.

I've however seen some growing pics and journels from Blackdog and Advanced and Hydrogrow which all showed pretty great real world results! The more I read from you guys and on this forum the more confused I'm getting..

And then there's the DIY option. I've started looking at that and it looks like a other viable option although I would have to do a hell of a lot of more studying and research cos I've got no clue as to how I would do it lol..

HOTBOX fixtures with high failure rates! COB tech is the way too go 3k for straight flower and 4k full cycle! it doesn't get any easier than that!

 

[JimmyIndica]

And the true LED growers claiming there numbers and being truthful your run them down by saying you needed the 4 k 6 k or what ever and that is the sad truth, or your lights were to far away ,, that is why you should of went this way lol

Most of your success comes from the toys so to say because you as a grower are like in the middle pack! meh like 1000 other ones! The reason I say this is? I have had things finish up 7-10days earlier than it should and the buds are better quality! U just havnt gotten around and paid the $ like us real growers to see it! and LED watt to watt outperforms hps in terms of light quality and efficiency! All the way around! U can see this too? spend the 2grand!? u got 2 grand right? I mean look at all that light/airy buds u got? stop sending me private messages! I don't have nothing to talk with u about!

 

[JimmyIndica]

Whats a LED grower?

 

[JimmyIndica]

I put my LEDs 4 to 16 inches awy! 16 during veg and 4 by the end of flower! No burning! No bleaching! Because theres air moving over my canopy!

Drop and start 5 tangie,4 purpog18,2ewe2,cotton candy cane, highpriority some 7 day some14. I just bought 2 more 200watt optic cxb3k80 to help out little. So that will make it 13 plants vegged 40days under 1340watts in 28sqft.shootin for 45oz!

I'm not quite sure why you would say 3k for flower only and 4k for full grow? On the Optic website their lights are 3k but can be used for the whole cycle?

That's quite a few different lights you have there? Is that the Area 51 on the right? Which lights have you experienced better success from with quality and yield?

 

[JimmyIndica]

The best unit available right now at this time unles u diy? 200watt opticlighting cxb3070 3000K ran an at 2.1 amps .10 inches from the canopy. Thats my opinion. Multiple smaller units is the way to go for coverage. They are RWs.

Its all preference! I like the stretchin for the indica doms I run! Watch out for chips being ran at half throttle. These chips are cheap enough to replace if needed. I will never need to send optic back, because I got spare parts handy. Heres the yield from a blueberryheadband grown with 200watt vero3k.

Excellent video

i remember when that first surfaced, funny as fuck

WTF hahahaha hey idiot this thread is about a led to replace 1000 watt ,, get back to your closet anonymous ..Posting shit like that what wrong with you ? but let me guess that is 1/2 pound haul there right ???
but before you fuck off please tell us what was the cost to get that yield hahah 300 - 500 - 700 bucks ???

If you are advocating MH over LED you are in for a pleasant surprise. Greengenes got 27% THC with LED grown bud, no UVA or UVB required. Maybe the reason high altitude has more kick is because it finishes cool and dry.

If you got 2 gpw from your fluoro grow you can expect 10 gpw from a COB LED grow. For the most part we are talking about photon count in the canopy, not much superstition required.

Another thing worth considering, when it is dimmed, LED gains a lot of efficiency but HID loses efficiency. Dimming during the switch from veg to flower and dimming during the last days of flowering may be beneficial to quality and increase gpw.

Your ladies look good, let us know when you switch to LED

If you got 9 pounds from your 1K HPS grow you can expect 18-27 pounds from a 1000W COB LED grow. We are talking about photon count in the canopy here, not much superstition required.

With all due respect, let us know WHEN you switch to LED

I still don't understand why type of lighting is playing such a key roll in thc percentages in some of your guys eyes.

 

[SupraSPL]

HID emits an 825nm infrared spike, raising canopy temps, evaporating terpenes and possibly converting THC to CBD. See greengenes lab results from the LED vs HPS Blue Dream side by side. The LED side had more terps and more THC. Same nutes same air etc.

Also, HPS has a lower percentage of its output in the blue spectral range. Not sure if that matters but worth considering.

CMH has a better spread and plenty of blue, but still has the infrared spike and efficiency is (desperately?) dependent on the cleanliness of its reflector, bulb surface and both sides of the glass if it is a cooled hood.

your a joke! my shit is paid for! 1st run! keep making hps buds! I don't put my shit on scale till I have dry qp bags! u weigh your shit wet! Whos the fucktard? Fucktard! 4oz plants is what I get! How the a/c for the hps? Your plants don't look good at all to me!

Lets not get started on lab results again. That was last night. We are all doing those numbers. If most of the people on this site got their shit tested you'd be blown away. 25-27 percent is the norm now a days. Light doesn't matter.
