LED Thread regarding stalk weight difference between LED & HPS

[Lordhooha]

Id still bet, if i did a side by side using a blackdog or kind, the hps would win. Let alone a better bulb.
Until all manufacturers start making leds as good as you guys are in DIY, and drop the price. The upfront, and long term costs are just too much and outweigh the reward.
Peace

You must have missed the obvious sarcasm in my post.

Lol, sorry that went way over my head.
Very dry

Yeah, there's no sarcasm font. Go read up on the LED subsection of the Indoor Forum here at RIU. Smoke a bowl, take your time, and absorb what's really going on.

 

[Tim1987]

Yeah. no shit. That was my point. Again, you are using outdated tech as your reference when it comes to LED


There are guys making plugn'play LEDs at a reasonable price point.

^ 2 solid examples


BTW - "long term costs" - what???

[/QUOTE]
What i mean is, if a hps bulb lasts 10 000 hrs, vs a led from a manufacture which costs a grand or two and lasts 50-100 thousand hours, you may have to change the bulb 10x but it still only costs 600bucks for good ones. Doesnt save you anything over time on a huge scale. Especially the upfront costs.

I'm new to LED's, but I do know a little about light measurement and PPFD. I bought this Optic 2 lamp, which is a mixed Cree COB/5W blend. For 300 bucks, I absolutely love it. I think it's as good as a 400 watt HPS (or close PPFD wise), but this heat output is SO MUCH less than HID, I no longer have to vent outdoors. Really reduced my stress levels!

Thats a great, contructive point. But i do think you would have done a shitload of research to find your gem.
Best argument for so far, by far.

Cool, but this is what a 600w hps can do without even being fully dialed in yet.

 

[thenotsoesoteric]

I wasted money on led then i got smart an learned how to use them an what to buy. Who cares about power savings? Most spaces I've grown have a limit to the power. You will get higher gram per watt numbers with led if used correctly that is a fact. If you have a warehouse sure hps
is cool but 4x8 or smaller and it's just stupid to buy hps. I'm sorry you can't seem to turn your brain on long enough to figure out how to use led. No I'm not mad got a bunch of led grown nug how can it be mad with a full jar.

I just posted a pic of just 1 of 4 plants grown under a 600w hps in a 4 x 4 tent, all documented here on riu, and pulled over 1 pound of dry bud with little popcorn. The main thing is I didn't have to veg the plants long or waste time and energy training plants to "maximize" my yield. I literally just vegged clones for 3-4 weeks, topped them and flowered them out with minimum effort. How is that stupid? I smoked on that bud for months, jars full.

What was your total weight? Grams per watt?

 

[LEDandCoffee]

I have to agree. I did the same.
They're a dime in a dozen.
Cant beat hps for reliability. I also found my led's just don't have the PAR to penetration, the hps does. My 600, dimmed to 400 stomps my vipar900 in my 4x4.
Led manufacturers, really need to up their game. There is waaaaaay too much DIY going on.
Id bet money, my shitty "GROWLUSH" $30 would beat an old "BLACKDOG", or KIND LED, if i used one to compare. And look how much money they still cost! A new bulb costs me 30 bucks. Even replacing them 2 x a year its still a saving over time.
If you were growinb in a warehouse for profit, youd be absolutely MAD, to use led. Let alone taking all the time to make, or pay someone to DIY.
I hear you dude. I think you raise a valid point.

Wooped a Vipar you say? Wow much impressed, whoda thought a Vipar would do poorly @ 26w sq/ft

I didn't weigh it down to the last gram. I weighed out 16 oz and nothing after that. I just wanted to know if I broke a pound and I did.

I never worry about gram per watt, as long as I get at least a half pound from a 400w and a pound from my 600w I'm cool.

Exactly this^^^^^.
Reliability and consistency always wins. Hands down.
Thats all hps are, extremely reliable.

GPW by itself doesn't mean to much. I can pull 1 g per W from my 600HPS pretty easily if I choose to.
I'm sure LED flower peeps can do the same.

We have however strayed from the topic, A strange topic...But a different topic none the less.

I'm just trying to tell you that I've pulled damn near a pound from a 350 actual watt blurple. So saying you pulled a pound from a 600w hps doesn't impress me, nor is it a good argument for hps over led. But whatever makes you happy

That's to be expected though isn't it as LED are more efficient,?

My point is that GPW means nothing unless you include veg time, strain etc etc etc......And the argument of LED vs HID is not the topic...is it?

 

[Tim1987]

I reckon there is a little to be said about the heat from a hps aswell, concerning enviroment,and can be subjective.
Where i a my enviroment is way too cold for pot 9 months of the year, to get great yield and quality. Especially during the night.
Running the 600hps saves me a shit tonne of heating costs. I just set my ambient temps on my thermostat.
Also you can feel a warm glow from the bulb, and feels just like a bright sun. The plants absolutely love that warm glow from a bulb aswell.
They think they are in the sun.

It indeed was not the original topic. But I'm not the one who turned the conversation in this direction.

If you are in a typically cold environment I would 100% agree that hps is a better option for you. Not having to add a heater and dehuey in a cold climate more than makes up for the discrepancy in efficiency.

I've used hps and now led. Honestly can't tell too much difference when growing the same strain in the same setup. However my led grown buds tend to be more resin-y (IMO). I also like having 1500 small light emitting sources instead of just 1 big ass one. Makes it easier to avoid hot spots.
Unless someone does a legit side by side where the only variable is the light, the "led vs. hps" debate will continue.

Exactly. You need to have your light and enviroment in sync. Their environmental factors play a huge role.
Your enviroment would be a lot different to mine, and vise - vesa. Also everybody elses.
Our enviroments definitely play a huge role. I think we can all agree on that one.
But i do have to say in my xxtra large cool tube during the middle of summer at 35'C. The top of my tent will be the same as the room.

Thanks for your honesty.
