The age old question HPS, MH vs LED

[Aussieaceae]

I prefer the experience of growing outdoor and I'd say, appreciate what it is a little more. (a plant not a drug)

There is some fantastic outdoor weed, though it isn't nearly as consistent, it is just as good imo.

On the contrary though, indoor is almost always pristine and more consistent.
Barely as often pests or disease, easier to control, consistent temperature and climate, minimal resin and terpine loss etc.

Weathered is probably how i'd describe outdoor and for some peoples tastes, it's a desirable quality. Throw that in with an exceptional season, that's some exceptional weed.

I think it really comes down to the individual's tastes.
Anyway lol, won't derail this thread, just wanted to add my own 2cents.
Back to HPS / MH vs LED

I think indoor is superior to outdoor because you can control the conditions.. 1 rainy shitty year makes it true.

Full-auto blackout greenhouses with retractable roof is the ultimate way to take advantage of both worlds

Lakeside on Shuswap Lake myself, where abouts are you?

I lived in Alberta (Calgary) for nearly eight years (time was mostly spent in the mountains), and I have to agree. I met some great growers in AB, and was fortunate to have been given some fantastic outdoor bud while I was there.

I'm in Vancouver.....formerly from Edmonton

day 30 with the new light MARS sp150( I know trash), in a 18" x 27" in closet. and is used for seedling's and clones

let me tell you this trash is working great, although I have to lower it to encourage stretch versus raise with MK/HPS so that was a bit of a learning curve

As far as HPS/MH vs LED... I'm going to tell you that modern LED is pretty fucking great. You can see our grows with HLG's for 3, and going on 4 grows with them. I think the biggest advantage is the heat and power savings.. you can see hard numbers in this thread.....https://www.rollitup.org/t/energy-costs-to-run-a-20x30-grow-numbers-posted.991964/

I don't care about incandescent lights so why do you keep ranting about them? Like I said, I'm growing marijuana not conducting a science experiment about different sources of lighting. I use an HID you use and LED. I don't care what light you use but apparently you care what light I use. I'd tell you to look in the mirror if you want to see retarded but knuckle draggers like you can't stand upright.

You are obviously an insecure pathetic retard that thinks that anyone that does things different than you is a retard. You use LED's so anyone else that doesn't is a retard. You don't grow organically so anyone that does is a retard. Remember this post of yours?



So you have basically called those that use HID lighting or grow organically retards. That's a damn good percentage of the people on this site. So what is your purpose for being here? All you do is insult the members of this forum. You have absolutely nothing to offer. Do you even grow marijuana? Or do you spend all your time fiddling with lights and reading all the marketing crap pushed by the LED light manufacturers? Lets see these great grows of yours where watt for watt you get double the yield of an HID. I know you can't show us those because they don't exist.

Oh, here you are calling someone else stupid.



So if everyone on this site is stupid I have to ask again, Why are you here?

Because incandescent lights are less efficient than HPS lights. If you think HPS is better than LED, then maybe it's because of the lower efficiency? Perhaps you should try an even lower one? Obviously you're retarded because this is somehow going right over your head.

I don't care what you use. I do care if you say that it is BETTER than LED, because there is no universe where that is true. You keep trying to make it seem like I'm saying you can't use it. I'm not. I'm saying you can't lie and say it's better.

I called people who are super into organics retards. I didn't say people who use HPS are retards. You keep trying to straw man me as being anti-hps. I used one for 20 years, they're fine. They're absolutely not better than LEDs though.

CRI actually has nothing to do with a light's effectiveness. Nothing. It is based on human perception and incandescent light. The only reason high cri is the rage is what happens within the spectrum of phosphor white LEDs. There is a shift to more and deeper reds. Also the reason for red/white Boards etc.

Metal Halide has a cri 4 times that of HPS if you check. Must vastly outdo HPS.

You seem to be having another one of your ignorant rants. I never said HID was better than LED. I have always stated that they both can be used to grow good weed. It's idiots like you that have to make a point of saying LED is better than HID. You're the retarded one. You are irrelevant. Your existence is meaningless. Your thought process is flawed. If you were an automobile you'd be subject to a recall. I rarely despise anyone but I despise you. If you were in shark infested waters I'd dump a bucket of blood in to attract the sharks.

No go back to doing what you do best and spank your monkey like a good little retarded boy.

I didn't say you said anything. You're just attacking me for it. So... it would make sense that you believe that. But perahps you're just so retarded you just mis-interpreted what I said to be something more simple that your retarded brain could understand and then got upset at that thing I didn't say.

sometimes its just better to agree to disagree and give it some rest. we're all growers here and should rather unite than split up by verbal bashing...

 

[Lordhooha]

I bought a few Gavita Pro 1700e’s this morning to add to my stable of lighting. im wondering how the Phillips driver is compared to the meanwell’s?

Guilty as charged...

So, @Houstonhydro, did that help you decide what to get?

 

[Dreaming1]

I have seen several HID grows. I have seen an all blurple grow. I dug the flowers.
I like to see actual, measurable, and meaningful numbers on growth,flower development,heat production,light production and spectrum, and power consumption. But, in the end, the power of the flower is all that matters. More dense vs looser, stankier vs cleaner, all of that is secondary traits to the effects for me.
So, I guess I'll stay with HPS and MH conversion until I get a quantum board set up. And then I'll give a more informed opinion. Maybe I'll run into one in the wilds and have seen more to make a better choice...

 

[kwigybo88]

LED's done correctly outperform HID lighting. Its not really a matter of opinion any more.

The only question is whether they're sufficiently superior to warrant the higher initial investment.

If you live in hotter climates then absolutely. If you dont then probably not.

I actually added 3-1000w HPS, mainly because of initial cost. I ran a ducted fan sucking fresh air through hoods and out the other end of room. Once I get my $$ up, I will be investing in LED but only high quality LED. Thank you all for the input...

I'm in the same boat. With each harvest I replace an HPS with an HLG led. 1 more and I'll be all L.E.D. Haven't regretted it yet.

 

[hillbill]

No need to switch all the same time, making any fraction of your space more efficient raises overall efficiency.

 

[moorebass70]

I cant wait till I meet someone who is using LEDs, I need to physically see the flowers they produce. On average 2 feet down into my canopy is solid. I'd love to use less energy and produce even nearly the same weight.
