Side by side grow. 630 CMH vs 1000HPS

[Dirt Bag]

Sorry to OP and this will be my only comment on the subject.

Dirt Bag, please be sure to support your points. You keep bashing DE but when I PMed you to offer you a free light so you could see for yourself, you made it clear that you had zero first hand experience and werent interested in actually comparing 2x 315 vs DE. you are spreading false information based on your speculation and opinion (which was formed without actually trying the product) and representing this as fact.

You can't breathe on the moon. I've never actually been there, but by the use of logic, deductive reasoning, and information provided by others, I can make this statement with confidence.
I've never driven a Ferrari, but can tell you with confidence that they are excellent machines.
And so goes my statement regarding DE CMH. The technology is flawed. I don't have to (nor wish to) use it to know it. Logic, reasoning, and information provided by others is sufficient to make the decision.
I made direct statements. Which do you contend are inaccurate? Which "fact" do you find untrue?
1) DE CMH bulbs (with multiple arc tubes) do not last as long as single arc tubes. The science supporting this fact is sound.
2). DE CMH costs significantly more.
3) DE CMH bulbs create a much bigger hotspot.
4) two Philips 930 bulbs produce more (and generally better) light than a 630 DE.
5) multiple bulbs create better canopy penetration.
6) Single ended CMH are more readily available.
These are facts as things currently stand. But I am certainly open to discussion. Nothing is carved in stone.

PS- you never mentioned free.

Ok i have read this thread till the end but have some unanswered questions. Do the cmh lamps need different ballasts than hps and mh and can they be dimmed? I discovered some sets with regular dimmable electronic ballasts (Lumatek) including cmh bulb, reflector and adapter for the e40 socket. Can these be used safely?

 

[Ibechillin]

Square wave ballasts are the optimal for CMH bulbs max lifespan (lower frequency more efficient), there are some digital ballasts that can be used with HPS, MH and CMH bulbs though and yeah they can be dimmed. I checked the Lumatek site out and the kit your looking at, the ballast is a square wave meant for CMH only.

Thanks for clarifying.

PLEASE NOTE: Philips bulbs that are not designated as agro utilize a special kind of glass called Fadeblock® that blocks UV, intended for indoor retail applications to help alleviate fabric color fading.
And NO, the one is NOT just the other without the jacket!

Where do you get the Elite Agro? Not a single online retailer understands the difference between any of these bulbs, I've ended up pulling the shields off em..

If i get glass in my bud oh well I'm not snorting the shit (anyone remember when Pyrex stopped using boro and didn't tell anyone?)

I’m of the opinion that if you’re getting 2lb per 1k de you’re not taking advantage of de lighting.

Great thread, incredible grow, very happy to see the results of air cooled HPS vs non glassed CMH. It's been years, but if memory serves me correct, an aircooled lamp drops from 5-10% of output.

Only thing that I'm noticing looking at the pics that really favours the CMH, it does seem that the cmh's are sitting right next to the HVACs... Cooler roots, cooler canopy.

If the HPS and the CMH were reversed on the sides of the garden, you might see the results change.

Yeah guys.. haters going to hate I guess.? Lol jezz, all my experience on this forum, I've never came across some dick weed like this.. it's not something we are all used to here. This place is about sharing knowledge and helping others and learning.! I owe this site to all the things I have learned.

Anyhow. Back on track here. Thank you for all the kind props my fellow green thumbers..!!






Final weight on the 630cmh side is 9 pounds 8 1/2 ounces. Almost 10.! I would have had way over 10 if I had more lighting on the plants that are on the walkway. My biggest light was 2 pounds 13oz. .3 lbs will now be my new target goal..

Just trimmed the first 3 plants from the hps and I got 19 ounces. So its neck and neck at the moment. But that's just the first 3. I will have a full report on hps yield by Saturday. Finally my other buddy who trims for me is freed up to come wednesday.. I'm over trimming. But hell I saved a couple grand doing it myself. Lol. Its actually not that bad because I get like 20 zips in like 4 hours. Love trimming indoors.!.

To be totally honest when I'm trimming this HPS side now, it really is a close call with Terps and the quality.. they both kind of look the same really. there isn't that much of a difference in Frost that I see. The HPS side is way more red hairs. And the cmh has more greens mixed in like outdoors.

So.. so far I'm absolutely astounded with the 630s. They proved without a doubt to preform..

I'll be back with more reports. And my total opinion on both when I finish this haul here. I've been a one man show lately. I usually have everything trimmed by now..

So an hps and a cmh together!? Chit man I ran hps and mh together for 7 yrs with zero issues........cmh just seems like a suped up mh

 

[Lyfespan]

Okay folks. Are you guys ready for more lies.? Are you ready for me to fudge my weights again.?? Cool well here I go.. hehe

Total weight on the HPS is 8 lbs 15 oz. So the cmh yielded more.! Total weight of the whole grow 18 lbs 7.5 oz.

So after digging deep and really getting into the trim on the HPS side. I have learned that the CMH is just a way better Light.. It produced a way better product. there was more Terps, the buds were way heavier, it was a dream to trim compared to the HPS. HPS had more larf. There was way more untrimmable buds. As where the CMH there was not that much air buds and larf at all CMH is just a considerable amount more of density going on.. I was amazed at the penetration as well deep down in the canopy. the buds were still hard and trimmable, as to where the HPS was very airy and Light. Weighing up an ounce of both sides the ounce on the CMH side fills up half the bag as to where the ounce on the HPS packs it full..

I'm 100% sold on the CMH. I'm converting my room to all 630s is now. It beat the 1000s hands down.. in all aspects. I was getting 9.5 and 9 oz and 8.5 oz plants on the regular with the cmh. The biggest plant trimmed in the hps was an even 8 ounces..

So that's my results guys.! I'm glad you guys enjoyed and thank you all for the props and kind words. I'm glad this grow went well so I could show you guys a good side by side.!!

My next grow in this room is Dosido. You guys can come check it out in grow diaries. "8 k coco grow show"

Aloha everyone. Happy growing.!

thank you for this post. i have been running the DE HPS for 4 years now and was wondering what the "trim" factor was on other lights after enjoying the production from 14 nanolux DE 1000s in a 12x24 room.

i have been contemplating multi spectrum or just cmh

 

[overbudjet]

First grow of the new room(lighting change du to this post ) 8 315 cmh (Philips 3100k Greenpower elite agro)over 46sqft V/S 6 600w Hortilux bulb over 54sqft same strain/flowering time. the new room give me almost a pound more of the nicest and resinous bud I ever grown(growing since i was a teanager almost 55 by now LOL...)For me CMH worth the change,by way another advantage of cmh is the nice spectrum almost like sun 92 on the CRI index.So thank you issack for this post

 

[Biologist]

Are people still finding that a 630W CMH equals the yield you get from a 1k HPS? I'm expanding my operation and looking at buying new lights. I'd love to switch to the 630W CMH to save $$ on electricity and heat generation but I don't want to lose yield. Issack's grow tells me it should be fine, but I did see a side by side on youtube where it seemed to take 3 315W CMH to get 124% of the yield of a 1k HPS on a light mover. That would put the yield from a 630 at something like 83% of a 1k HPS on a light mover.

Anyone else getting the same (or better) yields from a 630 that they used to get from a 1k hps?

i'm on my 3rd grown with 2x315's (actually 2, as fuk'd up the 1st) - i'm 58days into 12/12, and by eyeing the buds, 2x315 can't compare with the output of a 1000w.. the buds under the 315's are 1/2 the size- as i grow for quality, we'll see in a month ... but if u r a commercial grower and can deal the the heat, a 1000 is the way to go...

 

[Sunshineinabag]

Lmao if your a commercial grower the sun is the best way to go! Period!

agree 100%.... HOWEVER.... u n me would get opinions from others that indoor, underlights makes for a better product... i don't agree

 

[samiam]

1000 watt cmh ballast and bulbs are available now, been running them for a year now. Runs cooler, and some plants come off as much as a week earlier.

 

[Americangrower]

Pics don't lie. Anyone who's followed this thread can see clear as day 630w of cmh can compete with if not out perform 1000k of hps. Claims to the contrary looking pretty foolish to those of us that watched it happen with our own eyes.

couldn't agree more. I've been on IC for a long time. I have to say Issack's thread is 1 of the best if not the best side by side comparisons I have ever seen.

And that room

630 DE CMH are $270 from ceramic solutions, ads in the banners here.
Get your money back faster and more light than 2-315's....

Hey chunky do you run these yourself?? Ive been checking out the website but they always seem to be sold out. Thought I would ask you before I go ebay and alibaba aliexpress hunting. What can you speak on regarding these lights? Thanks for sharing .

 

[MartianMarvin]

This is why I asked, wanted to see what everyone said. I guess it really depends on environment and such. My buddy went from an air cooled 600 hps to non cooled 315 LEC and is killing it. Maybe the glass from air cooled is another variable. We noticed that the heat was about the same, but plants looked way healthier. Seemed to fade "prettier". Slight improvement in yield, but less watts.
Anybody have two 4x4s to run a side by side?

Bro have you ever ran those air cooled hoods WITHOUT the glass???!! The glass is permanently glary and dirty. I take out the glass and still run ducting on the hoods but inside the room recirculating sucking out of a carbon filter missile in front . Screw the glare from glass.
