LED manufacturer question

[Loollo]

But they aren't from Ikea, Cree ftw


My next LED cab will run a red/blue heavy LED array though.

Oh yes, the cab was of ikea !

Red and blue like me ?

I want to go NW and WW, strip and multichip, Side lighting and top mount. I don't see a problem with that, barring a few kitschy spectrums [UV, far red, etc.]

You seem to have a deep know-how in led technology. What do you think of my two led 50w 630nm and 10w 460nm ? I must add something or i could harvest well with this setup ?

Hello Loollo, I would be glad to help!

I would say your ok in the 460NM. When you get a specific color, that's not the only spectrum provided, its just the targeted spectrum. I think the 460 would be close enough to provide some of both the needed 430 and 470 targets.

Now The red you have I am not sure if it is going to get the job done properly or not. Sure it may make you some ok smoke and you should be pretty proud of that, but you could defiantly work to reach 640 and 660 range a little better and end up with a better result.

You always here stories of people having issues with flowering well with LED, the reason is the lack of effectiveness of the red spectrum's in the light. The better you meet those red spectrum needs the better yield and quality your going to get.

It is 4 times easier for a plant to absorb blue spectrum's than red, That's why you see even the cheapest of led lights can veg a plant.

What's up beanmeister

Want to address why cree whites kick ass?

I'd throw a hi power efficient white In there and kick a$$, along with a red of the same caliber

Something beanmeister can't offer.

This is not something I feel like arguing about. If you having great results with a full spectrum light it comes at no surprise because that's how we have been doing it for over 100 years. The bottom line is watt for watt a "properly" targeted spectrum led light will out perform a full spectrum light.

 

[positivity]

That sounds a lot better

Your 15% theory doesn't hold water

Real life experience shows they grow similarly in the end. But if number crunching and pink light floats your boat by all means enjoy the disco

What looks good on paper may not always work out that way in real life... FWIW, I'm a member of the pink LED crew but I'm seeing results that look similar from white LEDs. Do an internet search of "captainmorgan flowering with cree bulbs". I think that is an accurate representation of what white LEDs can do if you run a good strain and your feeding/watering regimen is right.

In the end, lighting is only one aspect of the grow. Managing all the factors properly is where great yields come from.

Here is a diagram of the LED wavelength array that I am using currently. There is a typo on it, the bottom circle is supposed to say "660" but it says "66". The manufacturer is evergrow, and I paid less than $1 per watt.



Here is a plant that is directly under a 268w (actual draw) evergrow LED, strain is btk kush. Medium is amended soil (roots organics soilless as the base), fed 5mL/gal general organics bio thrive bloom with tap water. The bio thrive and water are bubbled for 24-48 hours prior to use, and it makes a pretty nice tea.

Very nice Indianajones, great work

Good summation Indiana

I have nothing against the spectrums that supplement with just a little white or green. I grew that way for a long time and may change back if I see something that sways me, I'm completely open to the idea.

I just don't like it when I see people making strong suggestions that their way is the only way. Then go on to say using white heavy is a complete waste.

The evidence is there. Bottom line is it works well. If manufacturer reps, owners, or employees want to go on a public forum and go on about their studies, usually involving lettuce, they better expect to be tested.

Heavy flowers require high luminous intensity which these top bin whites seem to be providing.

But I could be wrong, they could be wrong. The point is debate it and prove it. I've put up my evidence and backed up my claim. And I'm not even selling anything...

Stay positive..lol

XT-E 6500K/450nm, XP-E2 630nm, Oslon SSL 80 660nm but yes, very similiar!

I recommend www.AdvancedLEDlights.com. I've been using them for about three years and they have worked well for me.

you got any proper pics detailing your grows using those leds?

if not, it sounds like spam.

People think the reviews on the Advanced website are all fake because they're all too positive but because I've actually used the lights, I'm a firm believer that they are real. The Diamond Series is rock solid. After I got the DS400 I knew I was done trying to find a vendor that sold lights that can maximize yield in an area.

 

[positivity]

Thanks for sharing the results. No doubt advanced led works well. That's one of the nicest results I've ever seen from an led grow

 

[Phychotron]

Thanks, that was a great harvest. By a strange turn of events that has left me budless, I'm smoking that top nugget right now. The top 6g's have been curing for almost year now. Its a little brown but smokes very smooth.

The rest of the plant did very well also, but it was in between a few other LED's.

dry total of 185g, with the top weighing 31g. I chopped her on day 51 when she was still going strong.

[bombadil.360]

very nice Psychotron!

let me ask you though: did you grow that plant from beginning to end with the DS400? did you order it with a custom spectrum?

did you grow only that one plant or more? if more, what was the total yield with only one DS400?

thanks!

peace

 

[Phychotron]

I started it under some t5's in veg then threw it under this for flower. It was in a 4x8 tent with a lot of other LEDs and many different plants, so its hard to say just what the fixture can do alone, but the plants under it end up stretching much less and grow much denser.

They only have their 11-band spectrum as far as I know.

 

[bombadil.360]

thank you for your honest answer man.
