GROWERS CHOICE LED(BETTER THAN HPS?)

I was thinking of switching over from HPS to the growers choice 680. But was wondering about a few things. Do LED put off alot of heat. Will i still yeild decent. Would the GC 680 be cheaper to run than a 1000 watt hps setup. Thank you to anyone who tried to help on the matter your times greatly appreciated.

It will be cheaper to run the led, the led will also produce less heat but in my opinion your quality and yield will decrease with the led.

P.S. THIS thread is a big argument waiting to happen lol.

I took a quick look at the data sheet available.
It appears to be on the level as far as wattage consumption claim, and output. All the numbers add up. I don't see anything I would consider an outlandish claim.
That light will cost roughly 30% less in power use, because it consumes 30% less.
Therefore, it will produce roughly 30% less heat than a lamp consuming 1000W.

My opinion is, as long as the measureables are factual, which they appear to be at a glance, it has the potential to compete yield wise with traditional HID lighting, of larger wattage consumption.

Never seen this one before now.
Where the F is the driver?

I'm sure in the black side bars

It's just a first point of emphasis for me...heheeee
Oh you got an LED, lemme see the driver...

still, hard to pay over $1

Yeah, that's a good thing to look at, because you can have some fancy new LED that nobody has even heard of yet, but if it is running on the worst driver you can get, it isn't worth much

Yeah, for those who can build, it really is.
These things are catching up though! Having certifications is a must for some markets, that's a factor.

@crewtight though really, the LED rabbit hole is reaaaallly deep, and there will be many varying opinions, it's pretty hard to keep the facts straight in the beginning.

Will you yield the same on the first run? Depends. Theres a learning curve with leds and its really hard to convince hpsers that they actually have to keep space hot instead of cold with leds: 81-84F. If no youll have problems when you give high wattage intensity.

Leds make a lot less heat. To me it seems like they heat less than those 70% of a 1000w: thermodynamics says 700w is allways 700w but i dont think this is the whole story: a light that heats its hotest point to a few hundred degrees will heat the space more than a big ass heatsink running a hundred.

Many people have problems with this, especially in openspace as its easier to lose hear during winter months. In tents the first led grow seems a lot easier.

And yield: it will probably look smaller to you, then you weigh in the pounds. Led buds look almost half as big but dont contain as much water as hps buds, they are compact and dense. Potency tends to go up as well, no infra red cooking away terps and cannabinoids.

I use hps and I think LEDs have come a long way and WILL be the light of the future if they aren’t already....
My basic understanding is that it uses power to convert to light. LEDs are more efficient and put out less heat than hid lighting, as heat is wasted power draw.
I’m looking at changing to cmh for better efficiency over hps and staying away from LEDs at the moment. Just too many knockoffs etc and false claims that it’s really put me off investing into LEDs atm.

Pretty much all light grows weed, some better than other in certain situations.

Theres a couple of things which makes leds attractive:
Directed light: all the light come out one side, you dont need to turn it with a reflector or hood.

Distribution: you can put it over and all.around your cannopy losing less light to walls, or having to hang it higher than wanted

And it makes twice as much light per watt.

I'm not familiar with Growers Choice, but it looks like quality gear to me.
They could give more info, I'd like to know what diodes and drivers. EDIT: The video below says Osram diodes.

A couple links to members running them, I suggest asking for opinions/updates in these threads.

Hey man thank you very much for taking out the time to help me. Appreciate your input.

Led weed is fire

Looks amazing

Short answer yes(also known as the broshure answer paper answer the deets)

Long answer no(also known as to long to explain yield over cost metrics still favour HPS becasue its a yield/volume contest not an efficiency contest)

Grams per watt vs grams per watt HPS gonna win everytime even when you factor cost..

Grams per cost of a Watt LED mops the floor with HPS

So LED obviously...you are probably not an industrialized farm..

No just a 8 plant monthly rotatin pretty much

Go LED if you want to have a long term reliable low maintenance, low power consumption & low heat option.

Go HPS if you want to deal with more heat, less consistent lighting and much more maintenance and power consumption.

A properly maintained HPS DE/SE garden will have the bulbs changed out every 12-16 months.. For me that was $80 x 6 + tax: +$500/yr..

A properly maintained LED fixture should require no maintenance other than basic dusting/cleaning and should last you several years before needing an upgrade which by then the light should've paid itself off many, many times..

Main Pros / Cons I've learned personally:
HPS: More Yield, More Heat, More Wiring, More Power Consumption (More Wattage (Pay More) & Amperage) & More maintenance (Spend More Time & Money).
LED: Less Yield (Not enough to outweigh savings from electricity costs & Heat issues), Less Heat, Less Wiring, Less Power Consumption (Less Wattage (Pay Less) & Amperage) & Less maintenance (Save Time & Money).

If you plan to just do a few grows to see if its for you or w/e then sure get HPS and over time you will definitely spend more, especially as more energy efficient appliances come out over the years. HPS is OLD SKOOL and will cost you just like an old V8 truck that gets 10 MPG and requires 7 quarts of oil vs a newer 4 cylinder that gets 30 MPG and requires 4 quarts of oil.

Up to you!
