Ok like the topic says many tend to think that 315 CMH or the CDM grow lights are producers for instance they state that the 315 watt CMH yields same as 600 watt HPS
Alright CMH growers with all bull shit set aside what are the numbers coming in at is it blowing 600's out of the water

Its not about what works right for you its about if it yields same or more then a 600 watt hps that so many are claiming i am being unbiased here one can say CMH has been out for some time now so should some numbers
what i am saying does it stack up to there claims that it yields same as a 600

No you are NOT! You're sad, lonely and bored. You wanted to start an argumentative thread to get some fussing going on.

That's ok. We here in the RIU are all about peace and love bro. We appreciate your sharing of the details of your sad, lonely life. Heck. It makes the rest of us feel better about our won lives. We really ain't got it that bad. We love you bro. Feel the love man. You should be having an awesome day just because YOU ARE AWESOME!

@Darth Vapour feel the love man.

On the "Graph" that everybody displays, they seem to radiate 3-4 times the amount of PAR light energy (across the whole "Growing" spectrum) compared to an "equal" HPS light. Ifthat's true, shouldn't they produce 3-4 times the yield (or, at least, a significant imrovement - perhaps at least double!)? The more reshearch I do, the more it seems that CMH'saren't that much better then a good MH/HPS "Dual Spectrum" light, or mixed HPS's and MH's used "side-by-side".

So the question is Growurown dank do you use CMH lighting and if so which one are you using ??? 315 watt ??? are you getting 630 dry grams per run on one of these and that is the question Again if CMH is suppose to be the grow light bomb then why is it not in everyones grow room >>>????
Or is it the numbers are not stacking up

haha what am i trying to sell but nothing just want to here from real growers unlike your self that have used or still do use CMH and what there results are is all,,,, nothing to do with selling anything

You changed the thread title. lol. It's all good bro. I swear I am going to have ease up on the kief for real. Stuff is like potent as well, pretty darn potent.

Since you mentioned 2000 vs 4000 RPM, that was for an automobile right? Seems like the true power range would be more toward the 4K end. Maybe a smidge higher. Would depend on a lot of factors. Like engine design. Of course Diesel engines are different. Their RPM range is tiny compared to an automobile gas engine. Then of course. A bike might have an even broader RPM range. And of course and as always, there are more factors in play here. Such as engine design and build.

So I don't really know the answer to your question. I personally think God is real. But, that's a personal relationship I have with God. And I don't mind if you don't feel the same way.

Yet, I like Trump. He's entertaining. May not be worth a damn as prez I honestly don't know. I admittedly haven't studied the issues. But he might be a hoot to listen to during speeches for 4 years.

I say just go with your gut on this one bro. Peace and love.

i couldn't resist the car analogy.
The power range of any engine is dictated on the design and volumetric displacement. Some can make up for displacement by either forced induction, direct fuel injection or variable valve timing/lift/duration, further more, wankel and some mazda engines like to incorporate even different methods.
Personally i like the advantage of a high-revving four cylinder with a variable valve train. BUT i commute in it, so having 210 hp in a car weighing a ton is good, i get 30mpg as long as i stay off the high cam lobes.
Annd if someone in a 40 thousand dollar BMW is being a dick, he can get stomped on by my 20yr old Nissan...
That is priceless by the way...

I personally am an atheist, but that's because science and me are buddies.
And i don't like trump.
So we are vastly different.
Now... about those CMH...

I am so flattered bro. I wasn't trying to be all sciencey about it or nothing. Apparently tho, maybe I have a knack for it? Peace and love.

Soon as someone starts a thread like this it becomes evident people go on the defensive this is not about anything other then having true growers that use this reply to what they see is better or not , did yields double 315 watt CMH if comparable to 600 better pull a pound for a novice grower just saying
Grease monkey i have come to realize most people like grow your on dank are real new to the lights growing so rather then answer like he did he should of been thinking this might be a good thread being look at what he is interested in

Its not about fighting with people on here anymore its about realizing that there wet behind the ear still

I'm starting to get that sciencey vibe now bro(toke). I think you're finally feeling the love man. Just be awesome!

What did you say again?

Oh yeah. Cars. Yeah, I like my motorvehicles. I like watching Chips reruns because that was during my era as a young adult. Old pintos, AMC lol, ten they got lots of bad ass camaros and stuff like back in the day. 15" 50 slickers with big old fat tires and stuff. I mean, I know it's old tech, but that shit is cool compared to today's 22"ers with that same ole spoke of different size mag wheels. Yeah, kinda stuck somewhere between the 60's and 80's. Though I like the new camaros too. Much better than stangs, tho I certainly appreciate them as well. Camaro is just my preference. But, anyway I really wish they would bring back the firebird trans am too. Good looking out bro.

I thought the cmh was discontinued?
So what do you think about the rear of the new corvettes? I mean, I don't know. They went so far away from tradition it doesn't look like a corvette rear end. Maybe it will grow on me. One of my favs is still the 78 Anniversary Special. Silver and black two tone with the red pin stripe. I mean I like them all, but for some reason I am drawn to that. Or the silver 63 split window. Yeah, that's probably my fav with te 78 running second.

I've been using the 315's for a year. Normally grow about 7-9 strains and don't go for yield, more variety, quality, pheno hunts, seeds and the like. Growing for yield and efficiency is about genetics and filling your maximum sq. footage with bud. I can run all the Blue Pyramid I want and won't get shit for yields in comparison to something like a Blue Dream or a cross I have that will pull ~1 oz. per gallon of medium. I did one run with 4x Blue Dream's in ~3.5 x 3.5'and pulled 13 zips total, one plant got some kind of root issue and pulled only 2 zips. Pretty sure with either of my producers, a clean 3.5 x 3.5 x 3.5' run it would pull an elbow. Not bad for a 315w bulb, SCROG/Hydro would likely pull more. Is it better than a 600? Too many variables unless you did a proper side by side, same environment, clones from same strain etc.. Does it matter? imo yes for flexibility and coverage, if I can run 2x 315w and pull 1.5 - 2 lbs. going for yield, I wouldn't switch to a single 600, or even the double 630 CMH. 2x 315's with the hood (Sun Systems) can cover 3.5 x 7ft (24.5 sq. ft.) well and in that setup I'd bet it could pull more than either 600 or 630 all other factors being equal.
