50 Watts of LED?

If ur going to use 50watt panel get two. Those panels LEDs are .5 watts. U need at least 1 watt per LED. U need high power LEDs . But they should work great for a couple plants. Only exception to high power LEDs are Lgm5 pro full spectrum LEDs. But u need like four bars.. Too over priced as well.. Good luck bro...

In my experience of driving my array with over 300 watts of dees supplemented with cfls I've found that a couple of... 26 watt cfls will create way more heat, and the plants will prefer to grow towards the dees, blue during veg and red during flower.

Id do the dees dude, but yeah I'd get two. I'm happy with putting down 80 watts per plant to get heavy fruiting.

I got a grow going with a 50 watt LED for 4 plants...I also added 4 35watt CFLs though. I just started but you can check it out https://www.rollitup.org/grow-journals/185954-led-cfl-1st-grow-stealth.html

Hello,

I was thinking of buying a 50 watt LED light panel with mixed red and blue bulbs for a full spectrum LED grow light. Will this be able to veg and flower a Lowryder? I am looking to grow like 4 plants max for my own personal purposes.

50 watts of L.E.D. provides enough lumens to grow two plants perfectly. With environmental safety being the deciding factor. It's a tiny bit more effecient than cfl but more expensive.

nobody answered the guys question i want to know the same thing im through with cfls

check the post above yours. Secondly, there is absolutely nothing wrong with CFLs, i've witnessed great yields with CFLs, just have to have correct conditions/parameters.

However, as lowryders generally don't get that large, i'd think one 50w unit would be able to grow 2 plants at most, however, there are a lot of variables here, like grow room dimensions, grow style, etc. If you have three plants in a tiny space, then i think that might work also.

Last point, there is a plethora of information that says red and blue alone(450nm & 660nm) will work, but will work much better with a broader light spectrum.(that CFLs do nicely for supplementing) I have also noticed this personally.

Definitely wouldn't recommend it; as an indoor grower, your mission is to provide your plants with light that simulates the sun as best it can (i.e. a full spectrun of color, in all wavelengths). Using only red and blue led's will omit out the other spectrums, which will hinder plant growth.

Just stick with a CFL if space is an issue.

The plant doesn't even absorb all spectrum of light. Shows how off base you are with LED vs other forms of light. Light is light, its all about getting the right spectrum to the plant when it needs it. When it comes to LED blue for veg and red for flower.

Piece of advice Silent, don't take advice from LED haters... they don't have a clue what they are talking about. 30 LED Watts = 450 Regular Watts

Everything you hear about lower yield is BS

I just figure anti-LED'ers get mad because they can't figure it out, or can't afford it, but I love the lower temps.

Lumen & Lux Are Irrelevant To Plant Growth

Unless the plants under your grow lights have eyes, lumens & lux make zero difference in how well your plants grow. Plants respond most efficiently to light that is beyond what humans can perceive so it does not necessarily matter how bright your light is. As a matter of fact, 80% or more of the light emitted by either the sun or from HID lights, goes unused by plants for photosynthesis. It is that portion of light that we humans see with our eyes and can register as being bright.

What matters most are the wavelengths of light that your grow light emits. When an LED grow light manufacturer rates their lights based on lumens, it is flat out misleading and irrelevant. Some manufacturers realize that people are starting to learn about this and are now skipping the word "lumen" and just showing pictures of how bright their light is. The result is the same - a bright light does not guarantee big yields.

Since you obviously know what you are talking about, can you define what you mean by "regular watts", in the comparison you just made...

That needs clarification. I've grown with led and if your talking about 30w of random led being equal to 450w that is totally absurd. To replace HID you'll need at least half maybe a little more than half of the total HID wattage in LED output (not chipset capacity!). It should also be a 3w chipset or better or it won't penetrate.

Also how did this thread revive itself, anyone else notice it started in 2008

im using a 63w 3w led in my flower room atm on the popcorn buds!! not too sure if its making a big diff should be!

Those comments are if you have the right wavelength LED lights for the stage, red vs blue. sorry i should have clarified a bit. You have to have the right LED colors / wavelengths to get the same quality!

Growbuddy, are you actually claiming that 30 watts of led light will produce the same as 450 watts of HID lighting?

I usually say about 50 led = 500 watts for a safety measure so I know for sure. Like I said, you have to have the right led lights, not just any random led lights, they have to be grow blue or grow red/orange lights.

Sorry, but i'm going to come out and say it. You have no clue what you are talking about, and the information you are giving out is incorrect and misleading. It's obvious from your other posts that you are relatively new to this stuff, so probably best not to try to pass yourself off as a expert.

EDIT: Just out of curiosity, what kind of panels are you currently running, and what kinds of yields are you pulling down?

haha fight?

Because you don't like LED? My other post is referring to veg only. Instead of trying to mix and match threads read and reply. If you dont like LED then GTFO - This thread isn't for you.

No, it's nothing new... you can't have any intelligent talk about LED lights because people act like that. LED TROLLS GO AWAY!

Just to back myself up, this 300 Watt LED light provides more plant friendly light than a 1000 Watt HPS

Not because I don't like LED, but because you are passing on grossly inaccurate and misleading information. I wasn't actually referring to your other recent post, just so we are clear, but either way your inexperience shows in the claims you make.

Care to answer any of my questions:

What is a "regular watt", and how do you know that 30 "led watts" = 450 "regular watts". Where are you geting this information.
What panels are you using (brand and wattage)
What yields are you getting with your setup, and how many grows have you done with it?

All reasonable questions, I think.

1) Because the LED light is producing similar light intensity and growth rate. A 30 watt led light (if on the right spectrum) provides similar light intensity and growth rate as a 450 watt hps light. (DEPENDING ON LIGHTS AND WAVE LENGHTS) All the wattage tells you is the required energy to power. People think the lumens are what makes a light, and it's not true, lumens are the measure of light HUMANS see (lumens are 100% useless when it comes to growing plants). Watts are simply a unit of measurement like INCH or YARD. Just because an HPS has more lumens, just means its brighter for humans, plants absorb only certain wave lengths of light, 90% of the light your HPS gives off is unused. That's where the savings are in LED. You're only giving the plant what it needs, nothing more, nothing less, there fore saving you electricity, money, and reducing heat energy.

The biggest thing to remember with LED is you HAVE TO HAVE THE RIGHT spectrums. (Chlorophyll production is made up of two parts, A and B. Maximum chlorophyll A production occurs at 662nm (for red) and 430nm (for blue), while maximum chlorophyll B production occurs at 642nm (for red) and 453nm (for blue). These are the peak points at which chlorophyll production is maximized) If you're LED's are on a different spectrum you won't get growth.

2) I'm upgrading my panels now, I used to live in Arizona so LED's were the best choice for closet growing. I have more room now so I'm going to branch out a bit and want

2x http://www.htgsupply.com/Product-120-Watt-Tri-Band-LED-Grow-Light.asp


With a couple back up red only led lights. Those two ^^ will give me up over 1000 watts of comparable light alone. (enough for 10 plants rough estimate) Using 10% of the electricity, and much less heat.

^^ Flowering

2x Blue light only for veg room,

and a mix lighting scheme for sprouts.


3) I get similar yields when using similar lightage, the different is I'm saving money on electricity, bulbs, ect. and I don't have to frat about burning down my house from my grow room, heat has never been an issue, I can put my lights where I want them and have no issues with heat or anything related.
