Is a cob putting out the umols and or CRI or have the penetration of the canopy or the 315? I'm sure it'll be less efficient but ,,,will it match up. I have cobs ( Area 51 units ) and I have a 630 sun systems I just purchased . I visibly see the difference . But I don't know the numbers behind the lights . I also have leds (Area 51 rw-150) and an 1000w DE . 1000w produces the most grams , LEDS produces the most terpenes and slightly higher thc levels so far ( spectrum) . But to each his own ... I just wanna see the numbers on the 630watt sun systems hood ... Would be nice to see the truth rather than Mumbo jumbo

Can you show us the test results? That would be neat. Thanks.

Oh you said that led produces higher thc and more terpenes. Just wanted to see your lab results you had done.

greengenes did a test on leds comparef 1000w hps . Terpenes were def higher and thc was as well . YouTube blue dream lab results greengenes ... You'll see his results . I'm not set up to run clones grown side by side and or have a lab I can send to . Cobs are one spectrum , and I haven't seen a side by side of cmh and LEDs . However the benefit of dual spectrum has to have a play In that I'd believe . But choose what you want mongo

Sure send me a spectrometer that's reliable and I'll post the results of 12-18-24 inches

Going to need more than a spectrometer, going to need a Chromatograph...

Looks, and feels won't cut it...

I believe Berfelo on youtube has already shown that terpene production is more or it brings out terpenes which the HPS doesn't... Yeild per a watt on the LED's is obviously higher due to efficiency, however the lack of UVB is pointing to similar THC levels as HPS...

So, if Terpenes, and Phenols go through a photochemical or electromagnetic process to create THC then it wouldn't be far fetched to think LED+UVB may produce better buds. If you can pull 1.5gpw off of LEC then what is the push to 1.7 or 2 gpw on a LED...

Well I just need someone to send me everything required for the cmh 630 and I'll tape my tent and give you the numbers !!!

Do you have a PAR meter, would be awesome to get the par readings off of it for a 4x4... Because I don't believe anyone has posted that yet... They cost 35 bucks for an el cheapo..

a lot of COBbers say otherwise.... i dont see the 315 matching a cob array run softly pushing 70% efficiency

I have a 200W (225W actual) COB LED fixture I'd LOVE to throw into a head to head with a 315W CMH setup. It's only 60% efficient, but I bet they'd produce similar results.

Comparison runs vs HPS are going to have markedly different outcomes than those run against 315W CMH, to the point of irrelevance in terms of terpene profiles.

That's a lux meter not a par meter. There's a difference... lux is effectively light available in the human visual spectrum while par is light available to plants for photosynthesis. I'm not going to bother explaining subtleties but they are not the same.

are the welthink ballasts significantly better than the philips or cheap chinese ones like in this kit?

Having read quite a few of your posts, I can tell you know your way around electrical equipment pretty well.

The efficiency advance of 315W CMH is not in the bulb. The essential thing for this system is that the ballast delivers a low frequency square wave output. The Philips unit certainly does and Welthink likely does, but doubts have been cast on others including the Hydrofarm unit.

Someone competent (hint, hint! ) should throw all these units on an oscilloscope and verify that the ballasts work as promised.

I am betting on terpenes will be higher and yeild, however CMH will have higher THC gotta have it tested though... LED Smokes HPS... Put me down for a .3 to .5 gram per a watt difference, and 1-2 new terpenes plus 10-20% more... ;) I am betting on a spread... THC 2-3% higher for CMH where is my bookie :eyesmoke: I believe LED is the way to go with some UVB introduced... Am going to end up buying some UVB lights and testing the UV index at different distances, so I can get my new build figured... Going to attempt 42x3590's and then get a uv index measure on 2x54 watt arcadia bulbs vs 2x40 watt phillips to decide where am going to go... I am going to just put 2xUVB bulbs between every row of 7 cob's. I like MAU5 grow mouse au's setup, however those freaken heatsinks are expensive as hell. Going with 5² and 58" long heatsinks w/ 7 cobs per a heatsink. I still believe you can tap in a bunch of mono's(620-630) in pattern along the heat sink to provide more reds...

So in the legal states are there meds available grown strictly with cmh lights as oppossed to reg mag hps or mh? All the technical jargon is wonderful but for me id have to try the final product.
