CMH vs LED vs HPS

[Crooked8]

So now we have snakedope and a dopesnake….hmm. Also Snake, or….snakes, i listened to them discuss lighting in that 2+ year old video. They make some valid points in defense of both types of lights. However, when it comes to leds, yes, you do have to buy a not dogshit brand, sorry, you get what you pay for in this world and the roi on leds is infinitely quicker when you are dialed in. But for you to say “tell me what lights you have and ill tell you if your product is good” is the most absurd and ignorant statement yet. Ive outlined my experiences with all these types of lights, ive shown photos of the product. Im spent on this redundant discussion. I could smack you guys in the face with the loudest dankest shit you ever saw and you would still cry about Leds. You guys can keep arguing why leds are inferior and get stuck in the past. Ill keep cranking 80+ g per sq/ft for 30% less cost while having consistent reviews of the product being “better than ever” from several pros who have tried the same strains under both cmh and hps. Very valid opinions I care about more than our cannabinoid and terp tests(which are all higher under led anyway). Take care, ignorance is bliss!

Ps- i saw Eye/Hortilux went out of business, wonder who is next? Wonder why they are down and out?

Landraces, you either love or loath them. ive got friends that say its weak or looks like dirt weed. But I grow them because i miss the weed from way back when. potency and looks are secondary factors to me when it comes to catching a nice buzz but i dont grow commercially like many others. Looks are everything if youre selling to dispensaries im sure

i luv landraces.... smokin in the late 60's/ear 70's was lots of mexico, then some columbian which was a step up, a few times , i paid up... ie 35bucks for an oz of jamaican , my friends thought i was nuts, then the thai/etc /etc ... yes i luv landraces, but i doubt... really doubt that ace or anyone else at this point has a true ... landrace that was not polluted.... at some point... with an indica.... and once that sativa lady get's 'boned' by an indica.... its in the genes...

Ace honduras sativa is the way to go. very damn close to that nice limey mexi brick weed from the 90's . Huge yields too no matter what lights you use

How long to finish that Ace?

2 of my 3 females went 12 weeks of flowering with 10 day veg. 3rd one went 14 . very reasonable for stuff of that quality

Don't wonder too much... It's obvious.
They don't want you to grow proper dope.
They deem HIDs dangerous and hazardous, so it's just a matter of time before you won't find them nowhere anymore, good times ahead of us

For home growers, you can still get CFL's and grow pretty good weed. Those big ass curly 43 watters work, and you can still buy them online, a little harder to find them in stores. There are plenty of older threads on here about them. I can already hear the knives sharpening to chop up this post, but it's true.
Disclaimer: I'm not saying they work better than any thing anybody else uses.

I still dont love the idea of not having hps as an option. I think they have a purpose especially for supplementing greenhouses. If i were to go HID again id stick to cmh 315s/630s(two bulb fixtures). They really do crank for what they are and I dont think those Phillips bulbs are going anywhere anytime soon.

Well maybe LED will hit that HPS spot in a few Years. But as some of u pointed out, LED's will be supirior in a blink of an eye. The only reason be, they are more cost effective $ pr. Watt. Dunno if Thats the route to go.... but the way have been paved, or should I say the spaceship har landed

 

[snakedope]

When they hit the 2000+ lm/par energy per diode then yes I think they will start to make crazy results, spreading them with low output already delivers awesome results in any parameter except quality, cuz quality is equal to light stress, spectrum 2nd
Light stress can only come from high rates light source/s.

High rates is at least 2000 lm a sec.
Try to grow with a 11w cfl or a 40w cfl, you will see a difference in end quality, this implies that there is a threshold of intensity for certain processes within the plant.
remember we are not talking about structure or density, just smoke.

i was wondering who would be the first to break the stunned silence.

This thread is painful to read with the amount of ignorance in here mostly based off 0 self experience . I spent 4 years running two facilities one with hps one with led. Done same strains in both about 80 runs of side by sides and led always won in quality and very close to yield , so much so I only run leds now

Anyone saying leds grow trash or worse than hps you don’t know how to grow with leds and have done 0 side by sides and just repeating what others say

What people don’t understand is the places you get flower from to form your led is trash opinion are mass production facilities , that wouldn’t put out good flower regardless of what light they use . There flower was trash with hps too. Because mass production makes shit flower not lights

Imo people hating on leds is just how people cope and justify the fact that they are paying twice as much to grow the same flower

And imo Athena grown flower has more to do with the amount of bad flower out there than leds do. Because I’ve used it and can confirm it grows trash flower. Many using leds are blindly using Athena at 3 EC

Learn how to grow flower properly with proper nutrition and the lights won’t make as much of a difference as you think , but hey I’d be lying to myself too if my power bill was double what it is now for no reason other than my ignorance and lack of skill

Leds @ 800ppfd max > any other light on the market . 1000+ ppfd Is your problem not the leds

 

[Hammerhead]

What our goal is will have an impact on what light we use. Commercial, Homegrown, power cost, brand loyalty all play a role. For me, my power use was the driving factor to go with mixed LED/CMH. If your using 1kw LED there's no reduction in power cost. Watts are watts they cost the same using any light. Most people will not tell any difference in the flower quality of LED.

I know people that used Athena and were not impressed. A few said jacks produced better quality lol.

NEVER !!! use the recommended EC levels from any nutrient vendor. They want you to use as much as possible to keep you buying sooner. The more frequently you buy the more profits they make. My EC never goes above 1.3.

 

[DJM]

I agree , jacks all day over Athena . GH 3 part is better than Athena

I think most people run leds way too high and that’s thier issue I know because I did it. Now I run an average of 750 ppfd at canaopy (leds set to 80% around 2 feet away) that puts out 516 watts and I’ve hit as high as 2.4 pounds off that 516 watts. My best gpw and quality to date. If you are hitting tops with 1000+ ppfd you’re gonna have to feed heavier and the light and ec will push more bio mass and quality will drop. I know because I did it. Drop ppfd to 750 , EC to 1.5 and you’ll see the true potential in leds . 2.4 pounds off 516 watts is hard to beat in my experience

With that said I’ve never ran cmh im only comparing them to DE hps

 

[Hammerhead]

I don't put much effort into yield improvements. I just do the standard topping/training with a good long veg time. Quality is all I care about.

hey man, it's delta9nxs here, i changed my handle.

good to hear from you!

i've been doing a lot of experimenting with leds for the last 4 years.

one of my experimental lights is 1680 watts and capable of 1500 umols at 30".

it's all screw-in bulbs, 2700k and 5000k, so i can change the spectrum around somewhat by using different percentages of the two color temps.

or remove them altogether to reduce light.

i did some very high dli grows (50-65 moles).

i am coming to the same conclusions you state above.

i am wondering what kind of light you are using and the spectral distribution?

most manufacturers are using combinations of "white" light. typically 3000k and 5000k.

and then adding some 660nm.

it appears Mars hydro uses a 2/1 ratio of 3000k/5000k and approx 2.7% 660nm supplementals.

very nice yield figures there!

do you have a current thread going on?

Not sure what to make of that, we hit over 1000ppfd with EC 2.0-2.4 max with co2 at 1000 and have no issues at all with quality. Either way its an interesting take. Thanks for sharing.
