Buds quality LEDs VS HPS

First off, I state fact, not made up hypothetical bullshit.

Secondly, I didn't "yell" at anybody. I typed plain, simple sentences.

Fun fact: it's easier to cool an HPS than an LED. You're spouting pure bullshit. You can slap an HPS in a tube and cool it with a single 4 inch fan. You can't put an entire LED fixture in a fucking tube. You spend FAR MORE on fans and circulation cooling LED fixtures than a single HPS bulb.

And again, learn to fucking read. I STATED IN PURE FACT that either was just as good and would get the job done. You're just once again making shit up to try to troll the populace as usual.
Your reading comprehension has failed you. Smoke a bowl and chill out, don't want you popping a blood vessel.

I've grown with both LED and HPS, I spent less on electricity with my LED grow than I did with my HPS grows, and produced roughly the same yield. HPS had maybe an ounce more.

So no matter your rhetoric or "PURE FACT", what works for me is different than what works for you. sport.

Edit: And by less on electricity, it was roughly $30 less a month... for 4 months.

Edit: I did however spend more on the LEDs than I did on the HPS setup.

Edit: Like I said earlier, to each their own.

Edit: Your tiny penis is tiny.

Edit: Here sweetie, I will hold your hand through this one... in reference to, "ease up, he was speaking hypothetically" ...

I have tested this multiple times, watt for watt quality COB lights run cooler than HPS. I did this again yesterday. One 600 watt HPS in a 5x5 tent with one fan and a 4" exhaust and an outdoor temp of 60*f. After a couple hours it was 83*. Swapped in 2 fixtures running at 475 watts each (950w at wall) and the temps never rose above 78*f.

The best COB on the market right now is roughly 25% more efficient than an HPS is. Unfortunately, that same fixture cost 325% as much to purchase. So, no. You're wrong. Flat out.
I'm not. You forgot that even the best HPS fixture needs a reflector and they cost you a minimum of 17%. So that 2100umol/s 1000W bulb only puts about 1750umol/s on the plants. So that's 1.75 actual umol/s/W. While COBs easily get 2.4. Most reflectors will cost you a lot more light. Especially the cheap ones will quickly lose 20% to 30% of the light.

Then with HPS you need to hang the light much higher too. Easily 3 or 4 times as high , which means wall losses are 3 or 4 times higher too. Easily another 10% to 20% lost.

It all adds up to a minimum of 40% extra light for leds per watt and up to 50% if you really want to. Going for that extra step to 50% can make sense if you are limited on the amount of power you can draw.

You are completely wrong on the costs too. A good HPS will wipe the floor with a cheap one and a DIY led is not that much more expensive anymore.

Before you talk more stupidity, look up my earlier posts and you'll see I've done all the math on it about 12 times.
Lol we have a tough guy over here. I actually made the switch from most efficient HPS to leds. So I actually know what i'm talking about. You just did the math wrong. Not really something to be so proud of.

Maybe I should not have @ so many like that.
I'm sorry, I did not mean for anyone to need to get involved, I should have said that.
I was just creating an example of differences I think I see in this section vs others.

It was a random selection of members from recent posts.
Hope the example was taken as a compliment by the overall group mentioned.
It was meant as a compliment.

Also to the rest I did not mean protect any noob from trolls. I meant if you were engaged in a good conversation with someone new to RIU. You would not let the troll take control of the conversation. That's all I mean. :peace:
Nah. Its cool. Couldn't remember what went on.

If you pay for your electricity then at least efficiency does make a big difference. Biggest part of the costs of growing cannabis is the electricity used. If you can decrease that by 40% to 50% then that's a huge saving.
I'm in a different situation than most indoor growers. I need the heat that my HIDs give off. If I were to spend a lot of money replacing my old magnetics with state of the art COBs I would be having to have a heater running all the time and not just during the dark periods.

As heaters don't grow bud but the lights do I'll be sticking to HIDs for the foreseeable future.

Yea, I'm running into the problem right now. My grow area during the night is around 62F and during the day around 72F. My T5 is not helping much, so I threw a 400w MH in there to get the temps up. Now they are sittin at 81F at night with lights on and around 74F with lights off.

When I need the heat, I use my dehumidifier and add CO2. I have setup to run sealed or vented, with or without CO2. Another option is a CO2 burner.
And I got a humidifier in there to get the temps up, and combat the dry AZ weather.

I am not in this argument it is getting worse even to read.

But if you only saved $120 on electricity and got an ounce less you lost more than you saved for the Grow.

My next crop is still small so I'm only running one HPS rig @ 400w. Gotta run a heater to keep temps @75.
They are growing fast so it won't be long before I'll have the entire space lit up & have to vent the heat.

Not if I reused the LEDs, which I did, to do another grow and saved another $120, and had to purchase $100 in bulbs...

But I get what you are saying.. it's close.

Edit: I grow for personal use, so not too concerned about yield. I like the trichs and density I get with LED more than with HPS.

I only meant on the efficiency of that grow.

But I think the smaller grower efficiency point is made.

That is the reason I have ditched the 315 cmh to put back a 600hps. The 315 costs me money. Even if I did a lot more per watt (which just isn’t as true as being stated for me) it is too small a bulb for a stand alone area in my room.

I would presume to guess that like LEDs (unless you get a lot of them), the 315 is "supplemental" whereas, nobody can argue HPS will yield results on its own, no matter the wattage. -- Not sure if I said that right...

Phillips designed the 315 3100k bulb to be a stand alone light source for horticulture but for our purpose you need more of them to equal the results.

I bet they work fantastic for herb or lettuce production at lower cost.

That’s the real point to every argument like this though. These are all just tools. Plenty of variety to pick the right one for each of us.

Any argument past which is the right tool for the specific situation is just for an agenda.

ive seen people grow great weed with LED
ive seen people grow awful weed with HPS
No offense but why do you even bother commenting on such topics? Like anyone selling a product is going to under sell their product?

It'd be like me asking a salesperson if a toyota was a better car while I'm at the honda dealership, lol.

And I've seen a lot of shitty LED grows, especially on this site. Guarantee that the average pot smoker could not ID hid vs led vs cmh buds in a blind test.
